Consonant Voicing Investigation

Abstract

Obstruct consonant could be detected by energy difference profiles. In thisproject, we investigate algorithm to detect three types of landmarks, [stopclosure], [stop release], [fricative closure]. As a result, Overall detection ratesfor stop closure and release are 71.3% and 82.3% for obstruent landmarks inTIMIT, and fricatives yield 83.2% and 81.9% respectively.
