Closure duration analysis of incomplete stop consonants due to stop-stop interaction.
نویسندگان
چکیده
An incomplete stop consonant is characterized either by an indistinguishable closure or a missing burst. If an incomplete stop happens due to a stop following another stop [stop-stop interaction (SSI)], its acoustics typically resemble that of a complete stop-one closure followed by a single burst. As a consequence, stop detectors would fail to distinguish an SSI from a complete stop. Analysis of the TIMIT corpus shows 35.04% incomplete stops (14.97% SSI). It is shown that by using automatically estimated (and hand-labeled) closure duration, complete stops can be distinguished from incomplete stops due to SSI with 69.66% (79.14%) accuracy.

Durational characteristics of hindi stop consonants
A study of the durational characteristics of Hindi stop consonants in spoken sentences was carried out. An annotated and time-aligned Hindi speech database was used in the experiment. The influences of aspiration, voicing and gemination on the durations of closure and post-release segments of plosives as well as the duration of the preceding vowel were studied. It was observed that the post-rel...

This paper investigates acoustic features correlated with voicing (VOT, stop duration, closure duration, release duration, voicing into closure duration, duration of preceding vowel and duration of following vowel) and with the place of articulation (spectral peaks) of stop consonants /p, b, t, d, k, g/. A corpus with these stops in initial, medial and final word position was recorded for six n...
متن کاملArticulatory reduction and coarticulation in Catalan three-consonant sequences.
Electropalatographic and acoustic data on Catalan /Ck#C/ sequences where # is a word boundary and /k/ is preceded by /l, s, r/ and followed by /b, m, d, l, n, z, r, ʎ/ were collected in order to test the hypothesis that the velar stop is most prone to be reduced and deleted next to consonants involving high articulatory and aerodynamic demands. Analysis results reveal the absence of a velar sto...
متن کاملDurational characterstics of hindi consonant clusters
In the present study various durations of closure, preceding vowel etc. have been studied in meaningful Hindi two consonant cluster words with stop consonants ( such as /s ptah/ (week) and / bd (word)). The data included 80 most frequently occurring clusters of Hindi language. All these words were recorded by five male speakers and analysed using the Sensimetrics speech station software package...
متن کاملEstimation of place of articulation in stop consonants for visual feedback
Speech-training systems providing visual feedback of vocal tract shape are found to be useful for improving vowel articulation. Estimation of vocal tract shape, based on LPC and other analysis techniques, generally fails during stop closures, due to very low signal energy and unavailability of spectral information. Based on estimated area values and line spectrum pair (LSP) coefficients before ...
