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 کاملRobust classification of stop consonants using auditory-based speech processing
In this work, a feature-based system for the automatic classification of stop consonants, in speaker independent continuous speech, is reported. The system uses a new auditorybased speech processing front-end that is based on the biologically rooted property of average localized synchrony detection (ALSD). It incorporates new algorithms for the extraction and manipulation of the acoustic-phonet...
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 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 کاملContextual Effects on Vo Stop Consonants In
A perception experiment on stop consonant voicing in (C)V1CV2 was conducted to test the effects of the preceding vowel. Five types of /ki/ as CV1 differing in closure voicing, vowel duration and vowel devoicing were spliced with a da-ta VOT continuum as CV2. Subjects’ judgment between the spliced kita and kida along a VOT range was compared with that of ta and da in isolation. Strong effects of...
