ABSTRACT:
A VF detecting apparatus capable of highly accurate vocal fry (VF) detection includes: a very-short-term peak detection processing unit framing a speech signal with a first frame of a first frame length and first frame shift amount and detecting each power peak; a short-term periodicity detecting unit framing the speech signal with a second frame of a second frame length longer than the first frame length and a second frame shift amount larger than the first frame length and determining presence/absence of periodicity in each of the resulting frame; a periodicity checking unit for detecting power peaks in those frames determined to have no periodicity, from among the detected power peaks; and a similarity checking unit for detecting, for each of the selected power peaks, neighboring power peaks having high cross-correlation and detecting the section therebetween as the VF section.
