In this paper the authors propose a completely automatic speake r independent system to recognize a ll six stop consonants in continuous speech. Thi s system makes use of three differe nt distinctive features including formant transitions, silent interval and voice onset time. One hundred and twenty sentences from six English speakers were selected and tested by the system. The results confirm ...

We report four experiments designed to determine whether visual information affects judgments of acoustically-specified nonspeech events as well as speech events (the "McGurk effect"). Previous findings have shown only weak McGurk effects for nonspeech stimuli, whereas strong effects are found for consonants. We used click sounds that serve as consonants in some African languages, but that are ...

Dichotic listening experiments show a right-ear advantage (REA), reflecting a left-hemisphere (LH) dominance. However, we found a decrease in REA when the initial stop consonants of two simultaneous French CVC words differed in voicing rather than place of articulation (Experiment 1). This result suggests that the right hemisphere (RH) is more involved in voicing than in place processing. The v...

The perceptual dependence of stop consonants on preceding fricatives (Mann and Repp, in press) was further investigated in two experiments employing both natural and synthetic speech. These experiments consistently replicated our original finding that listeners report more velar stops following [s]. In addition, our data confirmed earlier reports that natural fricative noises (excerpted from ut...

Cross-language studies have shown that Voice Onset Time (VOT) is a sufficient cue to separate initial stop consonants into phonemic categories. The present study used VOT as a linguistic cue in examining the perception and production of stop consonants in three groups of subjects: unilingual Canadian French, unilingual Canadian English, and bilingual French-English speakers. Perception was stud...

These experiments explored the claim by A. Lotto and K. Kluender (1998) that frequency contrast explains listeners' compensations for coarticulation in the case of liquid consonants coarticulating with following stops. Evidence of frequency contrast in experiments that tested for it directly was not found, but Lotto and Kluender's finding that high- and low-frequency precursor tones can produce...

This study examined whether visually presented bilabials consonants are better identified than velars in a CV (C = consonant; V = vowel) or VCV context. We also investigated whether voiced and voiceless consonants sharing a same place and manner of articulation could be differentiated from each other with visual cues only. Although it is generally assumed that voicing is mainly mediated by the ...

Consonant-Vowel (CV) construction is the most frequent syllable in Bangla. The present study examine the acoustic properties of Bangla four labial stop consonants [p, ph, b and bh] in the initial position in a consonant-vowel context with seven following vowels /ɔ, a, e, æ, i, u, o/. Bangla is a type of language that uses aspiration as an addition feature to distinguish phoneme. Bangla labial s...

Child productions of two-syllable strong-weak words like baby and cookie are observed to exhibit a wide range of implementations of the medial stop consonant compared to adult productions. Detailed acoustic analysis of these consonants reported here lays the groundwork for prosodic analysis of the role of foot structure in the development of production of bisyllabic words. Acoustic details of t...
