- Previous findings suggest that working memory capacity (WMC) is influenced by a dysphonic voice quality. The present study examines the influence of voice quality on sentence processing and word recall in a working memory task. Fifty-seven children (8:1–9:1 years old) with normal hearing participated. Working memory capacity (WMC) was assessed using a competing language processing task (CLPT) which consists of a sentence processing segment (judgements of semantic acceptability in sentences) and a final word recall segment. All children completed two versions of the CLPT; once listening to a typical voice and once listening to a vocally loading induced dysphonic voice. The two voices were recorded from the same female speaker. In addition, the children’s executive functioning was assessed using Elithorn’s mazes. The dysphonic voice quality significantly decreases scores on the sentence processing segment but not on the recall segment. Children with better executive functioning (i.e., response inhibition, organizing, processing, and planning) were less disturbed by the dysphonic voice in the recall segment. Children’s judgements of semantic acceptability in sentences in a working memory task are affected by a dysphonic voice quality, but not the recall segment (the measure of WMC). However, children with lower executive functioning may be more disturbed by the dysphonic voice. These findings suggest that listening to a dysphonic voice seems to require more cognitive resources than listening to a typical voice, but only when the task is sufficiently easy to allow for allocation of cognitive resources to process the degraded signal content.

- 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.

- Classroom acoustics not always take the speaker's comfort into consideration. The purpose of the presented papers was to investigate voice use, vocal behavior and prevalence of voice problems in Swedish teaching staff. Ratings of features in the work-environment on voice use were explored in n = 487 teachers. Based on their answers the respondents were split into two groups: teachers with self-assessed voice problems and voice-healthy teachers. Teachers with voice problems and were matched to a voice-healthy colleague from the same school and were investigated and compared for clinical findings and for vocal behavior. Acoustic properties of their teaching environments were measured. Teachers with voice-problems were more affected by any loading factor in the work-environment and were more aware of the room acoustics. Differences between the groups were found during field-measurements, while there were no differences in the findings from the clinical examinations of the larynx and voice. Voice problems seem to emerge in the interplay with and use of the classroom acoustics.

- Objective: The study aimed to examine the vocal behavior and self-assessed vocal health in women with varying everyday vocal load and functional voice problems, including patients with functional dysphonia, in three conditions: work, leisure, and a vocal loading task (VLT). Study Design: This is a longitudinal controlled, clinical trial. Methods: Fifty (n = 50) female subjects were tracked during 7 days' voice accumulation accompanied by a voice health questionnaire, containing general assessments with visual analogue scale and specific voice health questions. Subjects were divided into four vocal subgroups according to everyday vocal load and functional vocal complaints. Accumulation time was divided into three conditions: a VLT, work, and leisure. The following behavioral parameters were measured: (1) relative phonation time (%), (2) phonatory sound pressure/voice level (dB sound pressure level), (3) ambient noise level (dB sound pressure level), and (4) phonatory fundamental frequency (Hz). Results: Patients with functional dysphonia reported significantly higher specific voice problems across conditions and worse general voice problems during work and leisure than other groups. Women with high everyday vocal load and voice complaints showed higher phonation times and fundamental frequency during work than voice healthy controls. They also reported the highest incidence of general voice problems in the VLT. Conclusions: Vocal loading relates to prolonged phonation time at high fundamental frequencies. Patients with functional dysphonia experience general and specific voice problems permanently, whereas women with everyday vocal load and voice complaints recover during leisure. This may explain why the latter group does not seek voice therapy.
