Introduction: Aging reduces the ability to understand speech in noise. Hearing rehabilitation is one of the ways to help older people communicate effectively. This study aimed to investigate the effect of vowel auditory training on the improvement of speech-in-noise (SIN) perception among elderly listeners.   Materials and Methods: This study was conducted on 36 elderly ...

A COMPUTER-BASED ARTICULATION TRAINING AID FOR SHORT WORDS (CATA) Mukund Devarajan Old Dominion University, 2003 Director: Dr. Stephen A. Zahorian Several improvements in the vowel articulation training aid (VATA) are described, as well as the efforts to extend the visual feedback system to operate with short words in the form of consonant, vowel and consonant (CVC). The extended version of the...

Human beings can simultaneously recognize vowels in speech as well as gender of a speaker inspite of high variability. However, machines have not been able to simultaneously overcome both gender variability and vowel variability existing in speech due to gender. This paper uses a Multiple-Input Multiple-Output CoActive Neuro-Fuzzy Inference System to recognize both these patterns in speech simu...

In the field of speaker recognition, short utterance speaker recognition (SUSR) has been attracting more and more attention in recent years. Despite the advancement in this technology and use of phonetic cues for speaker recognition, the role of individual phonemes in carrying speaker information is yet quite an open issue. This paper presents a novel idea of using phoneme classes as a basis fo...

BACKGROUND AND OBJECTIVES The present study was carried out to investigate the effect of vowel context on the recognition of Kannada consonants in quiet for young adults. SUBJECTS AND METHODS A total of 17 young adults with normal hearing in both ears participated in the study. The stimuli included consonant-vowel syllables, spoken by 12 native speakers of Kannada. Consonant recognition task ...

Difficulties with second-language vowel perception may be related to the significant challenges in using acoustic-phonetic cues. This study investigated the effects of perception training with duration-equalized vowels on native Chinese listeners' English vowel perception and their use of acoustic-phonetic cues. Seventeen native Chinese listeners were perceptually trained with duration-equalize...

An experiment is presented here concerning perception of release bursts in a corpus of natural tokens of French /p,t,k/ in CV context. The focus of the study was the perceptual role of spectral characteristics of the release burst; therefore tokens have the same duration of nearly 25 ms so that neither VOT nor formant transitions may innuence listeners. Two training sessions appeared to be nece...

In this study we investigate whether non-native speakers using a speech recognition system would benefit from phone models of their own native language. For Dutch as the target recognition language, we found that American speakers do not in general benefit from American English models when speaking Dutch. However, using a CVC test methodology, we can conclude that for a certain level of profici...
