SOUND PROCESSING APPARATUS, METHOD, PROGRAM AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a sound processing apparatus of which the processing time of a sound signal is shortened. SOLUTION: The sound processing apparatus is provided with: a sound signal input means 11 of inputting a 1st sound signal; a loudspeaker 12 which transduces the 1st sound signal into a 1st sound and outputs it; a microphone 13 which inputs and outputs a 2nd sound; an echo canceler means 14 of outputting a 3rd sound signal obtained by reducing a sound echo component from the 2nd sound signal; a sound signal storage means 15 of storing the 3rd sound signal in time series; a speaking detecting means 16 of detecting a speech signal from the 3rd sound signal; a processed signal output means 18 of outputting a prescribed signal of the 3rd sound signal as a 4th sound signal; and a signal output control means 17 of performing control so that the processed signal output means 18 outputs a 4th sound signal when the speaking detecting means 16 detects a speech component. Thereby, the processing time of a sound signal is shortened. COPYRIGHT: (C)2005,JPO&NCIPI
