Title:
VOCAL FRY DETECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/026436
Kind Code:
A1
Abstract:
A VF detecting device (122) for detecting vocal fry (VF) accurately, comprising a
ultra-short period peak detection processing unit (162) for turning a speech signal
(102) into a frame with a first frame having a first frame length and a first frame
shift quantity, and for detecting a power peak at each signal, a short period periodicity
detecting unit (164) for turning the speech signal (102) into a frame with a second
frame having a second frame length longer than the first frame length and a second
frame shift quantity larger than the first frame length, and for judging the presence
of a periodicity at each signal, a periodicity inspecting unit (166) for selecting
a power peak within a frame judged to have no periodicity out of detected power
peaks, and a similarity inspecting unit (168) for retrieving adjacent power
peaks high in interrelationship from the selected power peaks and detecting a
section between them as a VF section.
