An acoustic-phonetic forensic-voice-comparison system extracted information from the formant trajectories of tokens of Standard Chinese /iau/. When this information was added to a generic automatic forensic-voice-comparison system, which did not itself exploit acoustic-phonetic information, there was a substantial improvement in system validity but a decline in system reliability.

Event-related potentials, recorded through a 128-electrode net, were used to study phonemic processing in the human auditory system. Within a stream of identical syllables, acoustic deviants were introduced that either crossed a phonetic boundary or remained within the same category. Two phonetic boundaries were explored, one present and the other absent in the subjects' native language. A larg...

A probabilistic framework for a landmark-based approach to speech recognition is presented for obtaining multiple landmark sequences in continuous speech. The landmark detection module uses as input acoustic parameters (APs) that capture the acoustic correlates of some of the manner-based phonetic features. The landmarks include stop bursts, vowel onsets, syllabic peaks and dips, fricative onse...

PURPOSE To develop a system for numerically quantifying a speaker's phonetic accuracy through transcription-based measures. With a focus on normal and disordered speech in children, the authors describe a system for differentially weighting speech sound errors on the basis of various levels of phonetic accuracy using a Weighted Speech Sound Accuracy (WSSA) score. The authors then evaluate the r...

Automatic phonetic transcription tools usually perform phonetic transcriptions directly from orthographic representations. Although these approaches often achieve good results, theoretical studies suggest that including morphophonological knowledge allows those systems to improve their performance. Following this idea, we developed a tool which first obtains an underlying representation of each...

This study seeks to improve our understanding of the e ects of microphone variations on speech recognition systems. The timit corpus provides data recorded on close talking and far eld microphones and over telephone lines. The summit system is con gured for phonetic classi cation and recognition. At the last icslp, we presented an analysis of the data and experiments in phonetic classi cation u...

The ACTOR® Text-To-Speech (TTS) synthesis system, developed at Loquendo S.p.A., is here described. The system employs a unit -selection concatenative synthesis technique, relying on labeled acoustic databases providing phonetic and prosodic coverage of the intended language/domain and on an original algorithm for run-time selection of the acoustic units to be concatenated. This technique yields...

We develop a system that lets people overcome language barriers by letting them speak a language they do not know. Our system accepts text entered by a user, translates the text, then converts the translation into a phonetic spelling in the user’s own orthography. We trained the system on phonetic spellings in travel phrasebooks.

This study explored the neural systems underlying the perception of phonetic category structure by investigating the perception of a voice onset time (VOT) continuum in a phonetic categorization task. Stimuli consisted of five synthetic speech stimuli which ranged in VOT from 0 msec ([da]) to 40 msec ([ta]). Results from 12 subjects showed that the neural system is sensitive to VOT differences ...

This paper reports on the correlation between word confusion matrices from Word-Error-Rate (WER) experiments and different phonetic distance measures. The investigated phonetic distance measures are based on the minimum-edit-distances between phonetic transcriptions and the distances between Hidden-Markov-Models (HMM). We show that phonetic distance measures are correlated with word confusion. ...
