OBJECTIVE This clinical trial investigated the ability of concurrent speech segregation in hearing impaired children. The auditory behavioral responses and auditory late responses (ALRs) were compared between test and control groups prior to vowel auditory training and after 3 and 6 months of vowel auditory training to find the effects of bottom-up training on concurrent speech segregation in h...

A series of experiments compare performance of trained classification trees t o multi-layer feedforward netRecent advances in classification with neural networks works on speaker-independent vowel recognition using inforhave been paralleled by advances in other techniques, and mation in a single spectral slice. The vowel stimuli are it is important to examine the most promising of these. In exe...

Programs for testing and training of difficult vowel distinctions in American English were created for subjects to access via the Internet using a web browser. The testing and training data include many likely vowel confusions for speakers of different L1s. The training program focuses on one distinction at a time, and adjusts to concentrate on particular contexts or exemplars that are difficul...

A visual speech training aid for persons with hearing impairments has been developed using a Windows-based multimedia computer. The training aid provides real time visual feedback as to the quality of pronunciation for 10 steady-state American English monopthong vowel phonemes (/aa/, /iy/, /uw/, /ae/, /er/, /ih/, /eh/, /ao/, /ah/, and /uh/). This training aid is thus referred to as a Vowel Arti...

Purpose The purpose of this study was to determine the effects of biofeedback on control of nasalization in individuals with typical speech. Method Forty-eight individuals with typical speech attempted to increase and decrease vowel nasalization. During training, stimuli consisted of consonant-vowel-consonant (CVC) tokens with the center vowels /a/ or /i/ in either a nasal or nonnasal phonemi...

The purpose of this research is to determine how models of human auditory physiology can improve the performance of automatic speech recognition systems. In this study, a series of experiments was undertaken to discover how humans categorize and confuse vowels in natural speech. The recognition task comprised a large number of vowel nuclei isolated from naturally spoken sentences of a large num...
