a palatal defect may result from surgical resection, and its consequences could include difficulty in speech and nasal regurgitation of food and liquids. an obturator combined to speech aid prosthesis can improve nasal emission during speech,  and  assist  in  preventing  nasal  regurgitation  of  food.  this  article presents a clinical report of the reconstruction of palatopharyngeal function...

In this article we describe the basis of the Fluency project for foreign language pronunciation training using automatic speech recognition. We describe the theoretical base, the interactive duration correction module, and our work toward adaptation to the way in which the user learns best. We show results in preliminary tests of the latter, and discuss future directions of the project.

When laryngectomy is performed for laryngeal or pharyngeal cancer, air from the lungs expelled through tracheostomy. The primary tone, which generated by vibration of vocal cords within body, can no longer be produced, resulting in permanent loss organs. An electric larynx (EL) has been used as a means communication patients after since 1959. EL cylindrical device that produces vibrations at ti...

In the design of hearing aids (HA), real-time speech-enhancement is done. The digital should provide high signal-to-noise ratio, gain improvement and eliminate feedback. generic performance towards different frequencies varies non uniform. Existing noise cancellation speech separation methods drops voice magnitude under environment. HA for frequency response suppression reduce required signal s...

Even though pediatric hearing aid (HA) users listen most often to female talkers, clinicallyused speech tests primarily consist of adult male talkers' speech. Potential effects of age and/or gender of the talker on speech perception of pediatric HA users were examined using two speech tests, hVdvowel identification and CNC word recognition, and using speech materials spoken by four talker types...
