Konferensbidrag (refereegranskat)abstract
- Our recent work within the research project SIMULEKT (Simulating Intonational Varieties of Swedish) includes two approaches. The first involves a pilot perception test, used for detecting tendencies in human clustering of Swedish dialects. 30 Swedish listeners were asked to identify the geographical origin of Swedish native speakers by clicking on a map of Sweden. Results indicate for example that listeners from the south of Sweden are better at recognizing some major Swedish dialects than listeners from the central part of Sweden, which includes the capital area. The second approach concerns a method for modelling intonation using the newly developed SWING (Swedish INtonation Generator) tool, where annotated speech samples are resynthesized with rule based intonation and audiovisually analysed with regards to the major intonational varieties of Swedish. We consider both approaches important in our aim to test and further develop the Swedish prosody model.

- PURPOSE: The aim of this report was to quantitatively and qualitatively evaluate the tissue response to bone-anchored implants retrieved from irradiated sites in patients. MATERIALS AND METHODS: The material consists of 23 consecutively received Branemark implants (Nobel Biocare AB, Goteborg, Sweden) placed in pre- or postoperatively irradiated sites. Twenty-two of the 23 implants were suitable for histologic evaluation of undecalcified sections in the light microscope. RESULTS: The oral implants with shorter time in situ demonstrated sparse bone to implant contact with mainly dense connective tissue in the interface. However, for implants with longer time in situ, high amounts of bone-implant contact and bone fill of threads were noted. The mean values of bone-implant contact and bone area within the thread were calculated to 40% (16-94) and 70% (13-96), respectively. The craniofacial implants, with the exception of two implants lined with a capsular formation, demonstrated mature and newly formed bone at the bone-implant interface. The mean value for bone-metal contact was calculated to 45 and 53% for two specimens. The mean value for bone area within the thread ranged from 65 to 88% for three specimens. CONCLUSION; The possibility to achieve bone anchorage of implants in irradiated tissue was supported by the findings in this study. However, due to limited material, conclusions with regard to radiation dose and bone tissue response to implants cannot be stated.

- The main goal of our current research is the development of the Swedish prosody model. In our analysis of discourse and dialogue intonation, we are exploiting model-based resynthesis. By comparing synthesized default and fine-tuned pitch contours for the dialogues under study, we are able to isolate relevant intonation patterns. This analysis of intonation is related to an independent modelling of topic structure consisting of lexical-semantic analysis and text segmentation. Some results from our model-based acoustic analysis are presented, and its implementation in text-to-speech-synthesis is discussed.

- The research project Simulating intonational varieties of Swedish (SIMULEKT) aims to gain more precise and thorough knowledge about some major regional varieties of Swedish: South, Göta, Svea, Gotland, Dala, North, and Finland Swedish. In this research effort, the Swedish prosody model and different forms of speech synthesis play a prominent role. The two speech databases SweDia 2000 and SpeechDat constitute our main material for analysis. As a first test case for our prosody model, we compared Svea and North Swedish intonation in a pilot production-oriented perception test. Näi{dotless}ve Swedish listeners were asked to identify the most Svea and North sounding stimuli. Results showed that listeners can differentiate between the two varieties from intonation only. They also provided information on how intonational parameters affect listeners' impression of Swedish varieties. All this indicates that our experimental method can be used to test perception of different regional varieties of Swedish.

- This paper introduces a new research project Simulating Intonational Varieties of Swedish (SIMULEKT). The basic goal of the project is to produce more precise and thorough knowledge about some major intonational varieties of Swedish. In this research effort the Swedish prosody model plays a prominent role. A fundamental idea is to take advantage of speech synthesis in different forms. In our analysis and synthesis work we will focus on some major intonational types: South, Göta, Svea, Gotland, Dala, North, and Finland Swedish. The significance of our project work will be within basic research as well as in speech technology applications.

Text-to-intonation in spontaneous Swedish
- 1997
-
Ingår i: Proceedings EUROSPEECH-1997. ; , s. 215-218
-
Konferensbidrag (refereegranskat)abstract
- This paper deals with a number of aspects of intonation in spontaneous dialogues in a language technology perspective. The key topics to be addressed are: I) the analysis of global intonation and its interaction with textual structure, II) the implementation of global and textual aspects of discourse intonation in an analysis-by-synthesis environment. We present models for the analyses of intonation and textual content in spontaneous conversations in Swedish. The models are implemented in a computational environment, making it possible to generate F0 contours, which can be imposed on a speech waveform using the PSOLA technique. The result is a text-to-intonation system, where textual and lexical analyses automatically generate hypothetical intonation contours, which can through resynthesis, and eventually be used in a text-to-speech system.

- One limitation with the Bone Anchored Hearing Aid (Baha) is too poor amplification for patients with moderate to severe sensorineural hearing losses. Therefore, we investigated if bone conducted (BC) sound transmission improves when the stimulation approaches the cochlea. Also the influence from the squamosal suture on BC sound transmission was investigated. Both sides of the heads on seven human cadavers were used and vibrational stimulation was applied at eight positions on each side with a frequency range of 0.1-10 kHz. A laser Doppler vibrometer was used to measure the resulting velocity of the cochlear promontory. It was found that the velocity of the promontory increases as the stimulation position approaches the cochlea; this was especially apparent at distances within 2.5 cm from the ear canal opening and when the stimulation position was in the opened mastoid. At frequencies above 500 Hz there was on average 10 to 20 dB greater vibrational response at the cochlea when the stimulation was close to the cochlea compared with the normal Baha position. Moreover, even if there were general indications of attenuation of BC sound when passing the squamosal suture, an effect from the suture could not be conclusively determined.

- Conclusion. This study on eye motility demonstrates a new application of electro-oculography which proved to have a high potential for establishing and diagnosing the cause of diplopia in orbital floor fractures. Electro-oculography is objective and easy to perform even when the restricted eye is covered. The ‘uninjured’ eye can be used as the reference. Any motility difference between the left and the right eye was easily detected. Objective. It is essential in orbital floor fractures to distinguish entrapment from other causes of diplopia. We investigated whether vertical eye motility and restricted elevation can be detected and characterized by means of electro-oculography. Materials and methods. Electronystagmography equipment used for vestibular testing in daily ENT practice was used in a different context. Unilateral mechanical restriction was generated in the test subjects through fixation of one eye bulb. The velocity and range of eye motility of both eyes were measured and compared in 12 healthy test subjects and 7 patients with long-term vertical diplopia after orbital floor fractures. Results. Simulated entrapment was easily detected as a distinct difference between right and left eye motility recordings (p<0.001). Recordings of patients with diplopia differed significantly from those of healthy test subjects with respect to velocity (p<0.05) and range of motility (p<0.05).

- Follow-ups of osseointegrated implants in the temporal bone have been limited to clinical stability and resonance frequency measurements. Standard computed tomographic scanning is restricted because of the high radiation doses to the brain and the presence of disturbing metal artifacts. The present study was undertaken to evaluate the use of cone beam computed tomography preoperatively and postoperatively.

- Background: There is limited knowledge of the long-term fate of “sleeping” or nonloaded implants in the temporal bone. Purpose: This article describes the fate of a fixture installed in the temporal bone that remained unloaded for 20 years. Patient and Methods: A 25-year-old male with hemifacial microsomia had three osseointegrated implants installed for an auricular episthesis and bone-anchored hearing aid (BAHA) in the left temporal bone in 1988. Two of the implants for the ear episthesis were activated the same year, but the fixture for the hearing aid was not uncovered until 2008. When the patient experienced hearing problems at his office, he wanted to reactivate the sleeping implant. An audiogram showed a maximum conductive hearing loss with good preserved cochlear function. Before reactivation, an Accuitomo three-dimensional, cone beam computed tomography was performed. Resonance frequency analysis (RFA) using the Ostell technique was done when the implant was uncovered. Results: Preoperative x-ray investigation showed the sleeping implant to be well integrated in the temporal bone, covered with 1 mm bone, and with no signs of resorption. Geometric measurements correlating to the two loaded implants showed the sleeping implant to be positioned too close to these to be able to anchor a BAHA without interference with the episthesis. Surgical exploration was done to analyze the implant. The clinical status correlated well to that diagnosed from the x-ray investigation. RFA revealed the implant to be well integrated. A new fixture and abutment for BAHA was installed in the temporal line and activated 2 months after surgery. The patient is today supplied with a BAHA. Conclusion: It seems possible to use sleeping implants in the temporal bone even 20 years after installation.

- CONTEXT AND OBJECTIVE: Osseointegrated implants have acquired an important role in the prosthetic rehabilitation of patients with craniofacial defects. The main indications are lack of local tissue for autogenous reconstruction, previous reconstruction failure and selection of this technique by the patient. This paper presents a clinical case and discusses indications and advantages of the osseointegrated implant technique for retention of auricular prostheses. TYPE OF STUDY: Case report, Universidade Federal de São Paulo (UNIFESP). METHODS: A female patient received three auricular implants after surgical resection of a hemangioma in her left ear. The time taken for osseointegration of the temporal bone was three months. After fabrication of the implant-retained auricular prosthesis, the patient was monitored for 12 months. RESULTS: The clinical parameters evaluated showed good postoperative healing, healthy peri-implant tissue, good hygiene and no loss of implants. Good hygiene combined with thin and immobile peri-implant soft tissues resulted in minimal complications. Craniofacial implant integration appears to be site-dependent; increasing age affects osseointegration in the temporal bone. The frequency of adverse skin reactions in peri-implant tissues is generally low. CONCLUSION: The surgical technique for rehabilitation using implant-retained auricular prostheses seems to be simple. It is associated with low rates of adverse skin reactions and long-term complications. Prostheses anchored by osseointegrated implants seem to provide better retention than do prostheses supported on spectacle frames, less risk of discoloration through the use of adhesives and better esthetic results than do prostheses anchored in the surgical cavity.

- PURPOSE: To evaluate the influence of PRP addition on bone repair of circular defects created in irradiated tibiae of rats by histometric analysis. METHODS: Sixty male Wistar rats had the right tibiae irradiated with 30 Gy. After 30 days monocortical defects were created and platelet-rich plasma was applied in 30 rats. In the control group defects were created but not filled. The animals were desanguinated after 4, 7, 14, 21, 56 and 84 days and the tibiae removed for histological processing. RESULTS: There was a tendency in the PRP group to increased bone neoformation from 14-days to 84-days; in the control group increased bone neoformation was not seen after 21 days or later. CONCLUSION: The addition of platelet-rich plasma had a beneficial effect in the initial cellular regeneration period and enhanced bone formation in later periods when compared to control.

- Nineteen patients previously treated with 52 implants for anchorage of craniofacial prostheses were subjected to implant stability measurements by means of resonance frequency analysis (RFA), six months to 15 years after implant placement. The resonance frequency (RF) of a transducer attached to the implant abutment was measured by using a frequency response analyser, a personal computer (PC) and dedicated software. Statistically significant higher RF values were seen for implants in the temporal bone as compared to implants in the nose and periorbital regions. There was a positive correlation with time since implant placement for the period from six months up to seven years. It was concluded that the preliminary results suggest that implant stability increases with time and that implants in temporal bone are more stable than implants in the bone in the nose and periorbital regions, probably reflecting differences in bone density.

Tidskriftsartikel (refereegranskat)abstract
- Percutaneous bone anchored hearing aids (BAHA) are today an important rehabilitation alternative for patients suffering from conductive or mixed hearing loss. Despite their success they are associated with drawbacks such as skin infections, accidental or spontaneous loss of the bone implant, and patient refusal for treatment due to stigma. A novel bone conduction implant (BCI) system has been proposed as an alternative to the BAHA system because it leaves the skin intact. Such a BCI system has now been developed and the encapsulated transducer uses a non-screw attachment to a hollow recess of the lateral portion of the temporal bone. The aim of this study is to describe the basic engineering principals and some preclinical results obtained with the new BCI system. Laser Doppler vibrometer measurements on three cadaver heads show that the new BCI system produces 0-10 dB higher maximum output acceleration level at the ipsilateral promontory relative to conventional ear-level BAHA at speech frequencies. At the contralateral promontory the maximum output acceleration level was considerably lower for the BCI than for the BAHA.
