Fricative production modelling: aerodynamic and acoustic data
The aerodynamic and acoustic phenomena involved in the production of fricative consonants are far from being completely understood. The overall Ievel and spectral characteristics of the radiated sound pressure are known to primarily depend on the aerodynamic state of the vocal tract, i.e. the pseudo-static pressure drop across the main oral constriction and the cross-sectional area of the const...
متن کاملAcoustic structure of fricative consonants in Greek
The present study examines the temporal and spectral characteristics of Greek fricatives (duration and spectral moments, i.e. mean, variance, skewness, kurtosis) as distinctive cues for their place of articulation. The effects of voicing, speaker’s gender and post-fricative vowel on both duration and spectral moments are also investigated. The results indicate that noise duration does not disti...
متن کاملFricative-stop coarticulation: acoustic and perceptual evidence.
Eight native speakers of American English each produced ten tokens of all possible CV, FCV, and VFCV utterances with V = [a] or [u], F = [s] or [integral of], and C = [t] or [k]. Acoustic analysis showed that the formant transition onsets following the stop consonant release were systematically influenced by the preceding fricative, although there were large individual differences. In particula...
متن کاملArticulatory, acoustic and perceptual aspects of fricative-stop coarticulation
Stops are not identi ed in the same way depending on preceding fricatives. According to Mann and Repp [1], such context-dependent variations in the perception of stops originate from the in uence of fricatives on how stops are produced. This study aimed further to explore this hypothesis. A rst experiment showed that the e ect of fricatives on the identi cation of stops tends to be conned to th...
متن کاملSegregation of stop consonants from acoustic interference
Speech segregation from acoustic interference is a very challenging task. Previous systems have dealt with voiced speech with success, but they cannot handle unvoiced speech. We study the segregation of stop consonants, which contain significant unvoiced signals. We propose a novel method that employs onset as a major cue to segregate stop consonants. Our system first detects stops through onse...
