Using a selective adaptation procedure, evidence was obtained for the existence of linguistic feature detectors, analogous to visual feature detectors. These detectors are each sensitive to a restricted range of voice onset times, the physical continuum underlying the perceived phonetic distinctions between voiced and voiceless stop consonants. The sensitivity of a particular detector can be re...

The present study explored the intensity level of authorial voice in relation to the quality of argumentative writing. 42 undergraduate learners of English as a foreign language (36 girls and 6 boys) spent 45 minutes to individually complete in-class position-taking writing tasks for three weeks. Their overall academic writing quality scores assigned based on portfolio assessment were studied i...

We evaluated the response of the voice-selective areas of the auditory cortex to sound 'voiceness', that is, the degree to which an auditory stimulus resembles human voice. Normal participants were scanned using event-related functional magnetic resonance imaging while passively listening to stimuli drawn from a 'voiceness' continuum generated via auditory morphing between sounds of voice and s...

Menopause effects a permanent change in certain body functions, including voice. If the voice is used continually as part of one's occupation, this may further impact on postmenopausal voice changes. The present study investigated individual and combined effects of menopause and professional voice use on voice. Ninety-two women were classified into reproductive (52) and postmenopausal (40) grou...

background: health?related quality of life (hrql) and voice handicap index (vhi) of laryngectomies seem to be relevant regarding voice rehabilitation. the aim of this study is to assess the impact on hrql and vhi of laryngectomies, following voice rehabilitation. materials and methods: a retrospective study done at the ear, nose, and throat department of the emergency county hospital. sixty?fiv...

The presented mobile payment system uses the GSM speech channel for data transmission. The speech channel is optimized for human speech transmission and, therefore, the transmission of modulated data is affected by various factors. The Echo Canceller and VAD systems are the factors having the greatest impact on performance of data transmission over the voice channel. For mobile phone payment, i...

A multimicrophone speech enhancement algorithm for binaural hearing aids that preserves interaural time delays was proposed recently. The algorithm is based on multichannel Wiener filtering and relies on a voice activity detector (VAD) for estimation of second-order statistics. Here, the effect of a VAD on the speech enhancement of this algorithm was evaluated using an envelopebased VAD, and th...

Voice activity detection (VAD) is one of the most critical issues on performance degradation of speech recognition in noisy environment applications. A real-time VAD was developed by using face parameters (eye and lip contours) as a front-end for the traditional speech and noise (audio) GMMbased method. Speech recognition performance of the audiovisual VAD is shown to be comparable with audio-o...
