摘要： In a speech judging section, a speech portion and a speechless portion of an acoustic signal are judged. Data of the acoustic signal are stored in a buffer memory. A memory control section controls writing of the data judged to be the speech portion in the speech judging section into the buffer memory, and reading of the data from the buffer memory. A time-scale modification section determines a time scale modification speed depending on an amount of residual storage data which have not been read out from the buffer memory, and modifies time scale of the acoustic signal depending on the time scale modification speed.
