AUDIO SPEECH/PAUSE SECTION DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a audio speech/pause section detector which can detect a pause section and a speech section easily and with high accuracy. SOLUTION: The audio speech/pause section detector is provided with a specific frequency component extraction means 3 which extracts a specific frequency component indicating fluctuation characteristics of speech at normal speed from a level signal indicating an amplitude level or power level of an inputted voice signal and a pause section detection means 5 which calculates envelope waveform of the extracted specific frequency component and detects a pause section by setting a prescribed slice level to a calculated envelope waveform signal.
