Separation of stop consonants
To extract speech from acoustic interference is a challenging problem. Previous systems based on auditory scene analysis principles deal with voiced speech, but cannot separate unvoiced speech. We propose a novel method to separate stop consonants, which contain significant unvoiced signals, based on their acoustic properties. The method employs onset as the major grouping cue; it first detects...
متن کاملDurational 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...
متن کاملTime-varying features of initial stop consonants in auditory running spectra: a first report.
Kewley-Port {1983) recently demonstrated that place of articulation of initial voiced stops could be identified from time-varying features observed in visual displays of linear prediction smoothed spectra. The present study extends this method of analysis in several directions. First, both voiced and voiceless syllable-initial stops produced at three speaking rates--normal, fast, and slow--were...
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...
متن کاملPerceptual invariance and onset spectra for stop consonants in different vowel environments.
A series of listening tests with brief synthetic consonant-vowel syllables was carried out to determine whether the initial part of a syllable can provide cues to place of articulation for voiced stop consonants independent of the remainder of the syllable. The data show that stimuli as short as 10-20 ms sampled from the onset of a consonant-vowel syllable, can be reliably identified for conson...
