Tidskriftsartikel (refereegranskat)abstract
- Purpose: This study examines the influence of voice quality and multi-talker babble noise on processing and storage performance in a working memory task performed by children using cochlear implants (CI) and/or hearing aids (HA). Methods: Twenty-three children with a hearing impairment using CI and/or HA participated. Age range was between 6 and 13 years. The Competing Language Processing Task (CLPT) was assessed in three listening conditions; a typical voice presented in quiet, a dysphonic voice in quiet, and a typical voice in multi-talker babble noise (signal-to-noise ratio +10 dB). Being a dual task, the CLPT consists of a sentence processing component and a recall component. The recall component constitutes the measure of working memory capacity (WMC). Higher-level executive function was assessed using Elithorn?s mazes. Results: The results showed that the dysphonic voice did not affect performance in the processing component or performance in the recall component. Multi-talker babble noise decreased performance in the recall component but not in the processing component. Higher-level executive function was not significantly related to performance in any component. Conclusions: The findings indicate that multi-talker babble noise, but not a dysphonic voice quality, seems to put strain on WMC in children using CI and/or HA.

Tidskriftsartikel (refereegranskat)abstract
- Prosody can be described as the rhythmic, dynamic, and melodic aspects of language. Swedish has a relatively complex prosodic system compared to, for example, English. A large percentage of Swedish children with language impairment show prosodic problems to some extent. In the present study, non-word repetition was used to assess the phonological and prosodic abilities in children with phonological language impairment and children with phonological-grammatical language impairment. In the study, 10 children with phonological language impairment and 14 children with phonological-grammatical language impairment from 4;3 to 6;2 years of age participated. All children heard the same recorded non-words and words. The group with phonological language impairment received higher scores in all variables, compared to the group with phonological-grammatical language impairment. The results showed significant differences between the groups regarding production of vowels correct in words and production of phonemes correct in non-words as well as production of unstressed syllables in non-words and production of correct stress in non-words. Percent correctly produced vowels in words, but not in non-words, correlated significantly with grammatical ability.

- Phonation into glass tubes (resonance tubes), keeping the free end of the tube in water, has been a frequently used voice therapy method in Finland and more recently also in other countries. The purpose of this exploratory study was to investigate what effects tube phonation with and without water has on the larynx. Two participants were included in the study. The methods used were high-speed imaging, electroglottographic observations of vocal fold vibrations, and measurements of oral pressure during tube phonation. Results showed that the fluctuation in the back pressure during tube phonation in water altered the vocal fold vibrations. In the high-speed imaging, effects were found in the open quotient and amplitude variation of the glottal opening. The open quotient increased with increasing water depth (from 2 cm to 6 cm). A modulation effect by the water bubbles on the vocal fold vibrations was seen both in the high-speed glottal area tracings and in the electroglottography signal. A second experiment revealed that the increased average oral pressure was largely determined by the water depth. The increased open quotient can possibly be explained by an increased abduction of the vocal folds and/or a reduced transglottal pressure. The back pressure of the bubbles also modulates glottal vibrations with a possible massage effect on the vocal folds. This effect and the well-defined average pressure increase due to the known water depth are different from those of other methods using a semi-occluded vocal tract.

Tidskriftsartikel (refereegranskat)abstract
- The significance of nasal resonance and anti-resonance to voice production is a classical issue in vocal pedagogy and voice research. The complex structure of the nasal tract produces a complex frequency response. This complexity must be heavily influenced by the morphology of the paranasal cavities, but their contributions are far from being entirely understood. Detailed analyses of these cavities are difficult because of their limited accessibility. Here we test different methods aiming at documenting the acoustical properties of the paranasal tract. The first set of experiments was performed under in vivo conditions, where the middle meatus was occluded by means of targeted application of a maltodextrin mass under endoscopic control. The efficiency of this occlusion method was verified by measuring the nasal nitric oxide (NO) output during humming. In another experiment the frequency responses to sine sweep excitation of an epoxy mould of a nasal cavity were measured, with and without elimination of paranasal sinuses. The third experiment was conducted in a cadaveric situs, with and without maltodextrin occlusion of the middle meatus and the sphenoidal ostia. The results show that some nasal tract resonances were unaffected by the manipulation of the paranasal cavities. Providing access to a maxillary sinus resulted in marked dips in the response curve while access to the sphenoidal ostium caused only minor effects.

- Objective: To analyze patients with a confirmed voice disorder in order to identify patterns regarding age, gender, and occupation compared to the general public. To explore effects of voice therapy according to the Voice Handicap Index (VHI) score pre- and post-therapy in relation to the number of sessions, age, and gender. Design: Prospective cohort study. Materials and methods: This study was conducted as a collaborative project between Linkoping University and hospitals in the south-east health care region in Sweden. Six voice clinics participated by asking their patients voluntarily to complete the Swedish version of the VHI at the beginning and end of therapy. Results and conclusions: The two most prevalent diagnoses were dysphonia (43%) and phonasthenia (25%). Among the working population, the three most common occupational fields were education, health care, and child-care. The majority of the patients were women (74.3%), and the mean age of all patients was 55 years. A significant improvement in VHI scores was found after therapy, with an average decrease of 19 median points in total score and a substantial effect size (0.55). The number of sessions did not significantly correlate with the mean VHI score difference but had a weak correlation to the start and end scores. Increasing age correlated with a higher median VHI score both at the start and end of therapy but did not affect the average decrease between the two measurements.

Tidskriftsartikel (refereegranskat)abstract
- The study aimed to investigate the effects of voice rehabilitation on health-related quality of life (HRQL) and voice function in patients treated for laryngeal cancer six months post-rehabilitation completion. A secondary aim was to identify factors that predict significant communication improvement.Longitudinal follow-up of randomised controlled trial.In total, 33 patients received voice rehabilitation post-radiotherapy and 32 patients constituted the control group. Outcome measures included patient-reported HRQL, communication and voice function (acoustic measures and perceptual analysis). Outcome measures were analysed one (baseline), six and 12 months post-radiotherapy, where voice rehabilitation was conducted between the first two time-points.Patients improved after voice rehabilitation with regard to communication function and HRQL and remained unchanged after 12 months post-radiotherapy. A significant roughness deterioration in the control group occurred between six and 12 months post-radiotherapy, yet remained unchanged in the intervention group. A factors increasing odds of significant communication improvement 12 months post-radiotherapy was voice rehabilitation. Smoking affected communication negatively.Voice rehabilitation appears to have positive effect on voice function and HRQL, which persist up to 12 months of follow-up and appears to prevent deterioration of perceived roughness. Patients who experience voice and communication problems at baseline are most likely to benefit from voice rehabilitation.

Tidskriftsartikel (refereegranskat)abstract
- This study examines the effects of an intensive voice treatment focusing on increasing voice intensity, LSVT LOUD¯ Lee Silverman Voice Treatment, on voice use in daily life in a participant with Parkinson’s disease, using a portable voice accumulator, the VoxLog. A secondary aim was to compare voice use between the participant and a matched healthy control. Participants were an individual with Parkinson’s disease and his healthy monozygotic twin. Voice use was registered with the VoxLog during 9 weeks for the individual with Parkinson’s disease and 2 weeks for the control. This included baseline registrations for both participants, 4 weeks during LSVT LOUD for the individual with Parkinson’s disease and 1 week after treatment for both participants. For the participant with Parkinson’s disease, follow-up registrations at 3, 6, and 12 months post-treatment were made. The individual with Parkinson’s disease increased voice intensity during registrations in daily life with 4.1 dB post-treatment and 1.4 dB at 1-year follow-up compared to before treatment. When monitored during laboratory recordings an increase of 5.6 dB was seen post-treatment and 3.8 dB at 1-year follow-up. Changes in voice intensity were interpreted as a treatment effect as no significant correlations between changes in voice intensity and background noise were found for the individual with Parkinson’s disease. The increase in voice intensity in a laboratory setting was comparable to findings previously reported following LSVT LOUD. The increase registered using ambulatory monitoring in daily life was lower but still reflecting a clinically relevant change.

Tidskriftsartikel (refereegranskat)abstract
- Mastering spatial and temporal co-ordination in speech production is a challenge for children. Voice onset time (VOT) reflects timing in speech. The objective was to study VOT in Swedish children with a diagnosed phonological impairment and compare results with normative data. Thus 38 children, aged 4-11 years, in three age-groups were audio-recorded when producing minimal pairs with the plosives /p b t d k g/. Waveforms and spectrograms were analysed. Results show that children with phonological impairment produced plosives with deviant VOT values and greater variability compared to normative data. No developmental trend was seen with increasing age. Also, no relationship was found between VOT values and degree of impairment measured by percentage phonemes correct. Furthermore no relation was found between number of errors on auditory discrimination of nine minimal pairs with the different plosives and number of deviant VOT. Findings were interpreted as displaying motor co-ordination difficulties.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: This study shows how the spatial organization of objects and their use may impact locally produced order of activities and how that can affect the accomplishment of everyday activities by people with dementia. Methods: The study is based on ethnomethodological conversation analysis of eight and a half hours of video recordings in three different settings. Eighteen sequences of activities identified were multimodally transcribed and analyzed. Results: The availability or non-availability of objects, their arrangements and manipulations play a crucial role in the management of the order of activities and may present both challenges and facilitations for people with dementia. The organizations of objects directly influence the order of the activity, and the objects' potential use may afford actions that deviate from the trajectory and the order of the main activity. Conclusions: One of the significant uses of objects is how they contribute to the perceptual field where attention is organized for building actions. Participants in activities modify the perceptual field by manipulating objects in the material surrounds in response to the relevancies resulting from the unfolding activities. Therefore, spatial contingency is significant in the accomplishment of activities by people with dementia. As it is not self-evident that verbal instructions may result in the instructed actions accordingly, the rearrangement of objects and making them timely available to people with dementia may increase the possibilities of keeping the order of the activities intact.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The purpose of this study was to investigate current knowledge of the diagnosis childhood apraxia of speech (CAS) in Sweden and compare speech characteristics and symptoms to those of earlier survey findings in mainly English-speakers. Method: In a web-based questionnaire 178 Swedish speech-language pathologists (SLPs) anonymously answered questions about their perception of typical speech characteristics for CAS. They graded own assessment skills and estimated clinical occurrence. Results: The seven top speech characteristics reported as typical for children with CAS were: inconsistent speech production (85%), sequencing difficulties (71%), oro-motor deficits (63%), vowel errors (62%), voicing errors (61%), consonant cluster deletions (54%), and prosodic disturbance (53%). Motor-programming deficits described as lack of automatization of speech movements were perceived by 82%. All listed characteristics were consistent with the American Speech-Language-Hearing Association (ASHA) consensus-based features, Strands 10-point checklist, and the diagnostic model proposed by Ozanne. The mode for clinical occurrence was 5%. Number of suspected cases of CAS in the clinical caseload was approximately one new patient/year and SLP. Conclusions: The results support and add to findings from studies of CAS in English-speaking children with similar speech characteristics regarded as typical. Possibly, these findings could contribute to cross-linguistic consensus on CAS characteristics.

Tidskriftsartikel (refereegranskat)abstract
- To meet the need for a linguistic speech perception test in Swedish, the ‘Listen-Say test’ was developed. Minimal word pairs were used as speech material to assess seven phonetic contrasts in two auditory backgrounds. In the present study, children’s speech discrimination skills in quiet and in four-talker (4T) speech background were examined. Associations with lexical-access skills and academic achievement were explored. The study included 27 school children 7–9 years of age. Overall, the children discriminated phonetic contrasts well in both conditions (quiet: Mdn 95%; 4T speech; Mdn 91% correct). A significant effect of 4T speech background was evident in three of the contrasts, connected to place of articulation, voicing and syllable complexity. Reaction times for correctly identified target words were significantly longer in the quiet condition, possibly reflecting a need for further balancing of the test order. Overall speech discrimination accuracy was moderately to highly correlated with lexical-access ability. Children identified as having high concentration ability by their teacher had the highest speech discrimination scores in both conditions followed by children identified as having high reading ability. The first wave of data collection with the Listen-Say test indicates that the test appears to be sensitive to predicted perceptual difficulties of phonetic contrasts particularly in noise. The clinical benefit of using a procedure where speech discrimination, lexical-access ability and academic achievement are taken into account is discussed as well as issues for further test refinement.

Tidskriftsartikel (refereegranskat)abstract
- Aim: Seeing a speaker’s face facilitates speech recognition, particularly under noisy conditions. Evidence for how it might affect comprehension of the content of the speech is more sparse. We investigated how children’s listening comprehension is affected by multi-talker babble noise, with or without presentation of a digitally animated virtual speaker, and whether successful comprehension is related to performance on a test of executive functioning. Materials and Methods: We performed a mixed-design experiment with 55 (34 female) participants (8- to 9-year-olds), recruited from Swedish elementary schools. The children were presented with four different narratives, each in one of four conditions: audio-only presentation in a quiet setting, audio-only presentation in noisy setting, audio-visual presentation in a quiet setting, and audio-visual presentation in a noisy setting. After each narrative, the children answered questions on the content and rated their perceived listening effort. Finally, they performed a test of executive functioning. Results: We found significantly fewer correct answers to explicit content questions after listening in noise. This negative effect was only mitigated to a marginally significant degree by audio-visual presentation. Strong executive function only predicted more correct answers in quiet settings. Conclusions: Altogether, our results are inconclusive regarding how seeing a virtual speaker affects listening comprehension. We discuss how methodological adjustments, including modifications to our virtual speaker, can be used to discriminate between possible explanations to our results and contribute to understanding the listening conditions children face in a typical classroom.

- The aim of this study was to investigate voice function in patients with birch pollen allergy. Voice recordings for acoustic analysis were performed during pollen season and non-pollen season, with 30 patients and 30 controls, and all participants answered a questionnaire about voice symptoms. The results show that the patients reported more voice symptoms than controls during both seasons. In the non-pollen season the symptoms were decreased in the patient group but not in the controls. Speaking fundamental frequency was lower in patients compared to controls during both seasons. The results suggest chronic edema of the vocal folds in the patients. Laryngeal examination with stroboscope was not performed but is recommended for future patients diagnosed with an air-borne allergy.

Tidskriftsartikel (refereegranskat)abstract
- The stumbling-block in voice therapy is the patient's generalization of the new voice behavior in everyday life. Traditionally voice therapy is based on demonstration, i.e. during the therapy session the speech therapist uses her own voice and body to demonstrate for the patient how to produce voice in different training tasks. During the last decade a new voice therapy strategy, the Verbal Instruction Model (VIM), has been developed by the author. In VIM the speech therapist uses verbal instructions instead of demonstration when conveying the training tasks to the patient. Our clinical experience has shown that VIM seems to help getting over the stumbling-block of generalization. However, evidence for VIM voice therapy outcome remains to be scientifically studied and confirmed. The purpose of this paper is to describe VIM voice therapy and to discuss therapy strategies in the light of motor learning principles.

Tidskriftsartikel (refereegranskat)abstract
- The present study aims at exploring the influence of voice quality on listening effort in children performing a language comprehension test with sentences of increasing difficulty. Listening effort is explored in relation to gender ( = cisgender). The study has a between-groups design. Ninety-three mainstreamed children aged 8;2 to 9;3 with typical language development participated. The children were randomly assigned to two groups (n = 46/47) with equal allocation of boys and girls and for the analysis to four groups depending of gender and voice condition. Working memory capacity and executive functions were tested in quiet. A digital version of a language comprehension test (the TROG-2) was used to measure the effect of voice quality on listening effort, measured as response time in a forced-choice paradigm. The groups listened to sentences through recordings of the same female voice, one group with a typical voice and one with a dysphonic voice, both in competing multi-talker babble noise. Response times were logged after a time buffer between the sentence-ending and indication of response. There was a significant increase in response times with increased task difficulty and response times between the two voice conditions differed significantly. The girls in the dysphonic condition were slower with increasing task difficulty. A dysphonic voice clearly adds to the noise burden and listening effort is greater in girls than in boys when the teacher speaks with dysphonic voice in a noisy background. These findings might mirror gender differences as for coping strategies in challenging contexts and have important implications for education.

Tidskriftsartikel (refereegranskat)abstract
- Background: People with dementia frequently suffer from communication disabilities, which usually influence their quality of life. The communication disabilities may affect a persons possibility to participate in interaction as a result of reduced ability to initiate new topics and difficulties in contributing new information to maintain the conversational topic. Technical aids have been proved useful to facilitate communicative activities by supporting memory and stimulating communicative initiatives. Purpose: The aim of the present study is to further understandings of how digital communication support may be used in interaction involving people with dementia. A further aim is to investigate how participants experience communication with and without the use of communication aids. Methods: The study is carried out in a Swedish context, and three dyads of older women with dementia and professional carers participated in the study. The dyads interact in the home environments of the persons with dementia using tablet computers and two web-based applications with generic pictures, videos, and music files (Computer Interactive Reminiscence and Communication Aid, CIRCA) and personalised pictures and films (Computer Interactive Reminiscence and Communication University of Sheffield, CIRCUS). The data include twenty-one video recorded activities. Results and Conclusion: The applications appear to provide support for the dyads in finding things to talk about. The participants talk both about the material and memories associated with the material. The participants experience the use of communication aids as positive.

Tidskriftsartikel (refereegranskat)abstract
- Observational learning has shown to be a successful intervention for writing. Up until now, however, studies have only been performed with normal-hearing participants, usually highschool or university students. Additionally, there have been conflicting results in whether subjective text quality correlates with one or more objectively measured text characteristics. In this study, we measured the effect of observational learning in a group of four university students with hearing impairment, and compared the results with those of a group of ten students with normal hearing who did the same intervention, and those of a control group consisting of ten students with normal hearing who did not do the intervention. Subjective text quality ratings and nine objectively measured text characteristics were collected for three argumentative texts written by each of the participants. In between writing these three texts, the participants in the experimental groups watched a video of a model writer who read out loud and corrected a similar kind of text. The statistical analysis showed significant correlations between the subjective ratings and four out of the nine objective measures, but no significant intervention effect. These findings suggest that observation-learning intervention is most effective when the model writer is a peer learner, and when the intervention is stretched out over time. Additionally, the method may be better suited for learners younger than the ones who were included in the present study.

Tidskriftsartikel (refereegranskat)abstract
- The study investigates the effect of voice quality and competing speakers on perceived effort in a passage comprehension task in relation to cognitive functioning. In addition, it explores if perceived effort was related to performance. A total of 49 children (aged 7:03 to 12:02 years) with normal hearing participated. The children performed an auditory passage comprehension task presented with six different listening conditions consisting of a typical voice or a dysphonic voice presented in quiet, with one competing speaker, and with four competing speakers. After completing the task, they rated their perceived effort on a five-grade scale. The children also performed tasks measuring working memory capacity (WMC) and executive functioning. The results show that voice quality had no direct effect on perceived effort but the children’s ratings of perceived effort were related to their executive functioning. A significant effect was seen for background listening condition indicating higher perceived effort for background listening conditions with competing speakers. The effects of background listening condition were mainly related to the children’s WMC but also their executive functioning. It can be concluded that the individual susceptibility to the effect of the dysphonic voice is related to the child’s executive functioning. The individual susceptibility to the presence of competing speakers is related to the child’s WMC and executive functioning.

- Objective: This study explores the effect of voice quality and competing speaker/-s on children’s performance in a passage comprehension task. Furthermore, it explores the interaction between passage comprehension and cognitive functioning. Methods: Forty-nine children (27 girls and 22 boys) with normal hearing (aged 7–12 years) participated. Passage comprehension was tested in six different listening conditions; a typical voice (non-dysphonic voice) in quiet, a typical voice with one competing speaker, a typical voice with four competing speakers, a dysphonic voice in quiet, a dysphonic voice with one competing speaker, and a dysphonic voice with four competing speakers. The children’s working memory capacity and executive functioning were also assessed. Results: The findings indicate no direct effect of voice quality on the children’s performance, but a significant effect of background listening condition. Interaction effects were seen between voice quality, background listening condition, and executive functioning. Conclusions: The children’s susceptibility to the effect of the dysphonic voice and the background listening conditions are related to the individual’s executive functions. The findings have several implications for design of interventions in language learning environments such as classrooms.

- Objective. The present, preliminary study was designed to investigate whether the results of the use of a detailed assessment protocol ad modum the Mayo Clinic rating of dysarthria and that of a more general assessment protocol, corresponding to ratings of deviances of the different speech production processes, differed primarily in terms of reliability.Patients and methods. Recordings of text readings of 20 patients with various degrees and types of dysarthria were assessed using both protocols by five clinicians with extensive experience in assessment of neurogenic communication disorders, and results from both assessments were compared.Results. The general assessment protocol was carried out with higher intra- and inter-rater reliability compared with the detailed assessment protocol. Perceptual deviations were identified in the same domains using both protocols, although only the more detailed protocol could be used to specify particular audible symptoms. Monotony, imprecise consonants, and harsh voice were the most prominent deviations identified with the detailed protocol.Conclusion. It is concluded that a general assessment protocol is sufficient to identify problem areas reliably and indicate severity of dysarthria but needs to be complemented with a short description of the most prominent audible symptoms and an assessment of intelligibility.

- Objectives: The first aim, was to compare participant compliance with postoperative voice rest advice in two groups. The second aim was to compare vocal function and recovery in the short-term, seven days post-surgery and in the long-term, 3–6 months post-surgery. Design: Preliminary randomized prospective blind clinical trial. Methods: Twenty patients scheduled for surgery for benign vocal fold lesions were randomized into seven days of absolute or relative voice rest. Compliance with voice rest advice was monitored with a voice accumulator for seven days following surgery. Vocal recovery was tracked through (a) self-perceived vocal function, (b) perceptual assessments of voice recordings and (c) visual assessment of high resolution and high speed digital imaging (d) vocal stamina and reaction to vocal loading, explored with a vocal loading task. Results: The absolute voice rest group phonated significantly less than the relative voice rest group during seven days post-surgery, but they were not silent. The absolute voice rest group self-reported more difficulty with compliance than the relative voice rest group. The relative voice rest group coped with significantly more vocal loading at long-term check-up. In the short-term the absolute voice rest group improved morphological recovery to a significant degree, however relative voice rest renders superior long-term recovery. Conclusions: Absolute voice rest is difficult to comply with. Neither short-term, nor long-term vocal recovery differed significantly between groups. Within-group comparisons showed significant improvements in vocal stamina, immediate recovery from vocal loading and self-assessments of voice problems only for the group with recommended relative voice rest.

- Resonance tube phonation in water (RTPW) is commonly used in voice therapy, particularly in Finland and Sweden. The method is believed to induce a lowering of the vertical laryngeal position (VLP) in phonation as well as variations of the oral pressure, possibly inducing a massage effect. This pilot study presents an attempt to measure VLP and oral pressure in two subjects during RTPW and during phonation with the free tube end in air. VLP is recorded by means of a dual-channel electroglottograph. RTPW was found to lower VLP in the subjects, while it increased during phonation with the tube end in air. RTPW caused an oral pressure modulation with a bubble frequency of 14-22 Hz, depending mainly on the depth of the tube end under the water surface. The results indicate that RTPW lowers the VLP instantly and creates oral pressure variations.

- Few comprehensive spelling tests are available in Swedish, and none have been validated in adults with reading and writing disorders. The recently developed STAVUX test includes word and pseudoword spelling subtests with high internal consistency and adult norms stratified by education. This study evaluated the convergent and diagnostic validity of STAVUX in adults with dyslexia. Forty-six adults, 23 with dyslexia and 23 controls, took STAVUX together with a standard word-decoding test and a self-rated measure of spelling skills. STAVUX subtest scores showed moderate to strong correlations with word-decoding scores and predicted self-rated spelling skills. Word and pseudoword subtest scores both predicted dyslexia status. Receiver-operating characteristic (ROC) analysis showed excellent diagnostic discriminability. Sensitivity was 91% and specificity 96%. In conclusion, the results of this study support the convergent and diagnostic validity of STAVUX.
