Abstract

A power calculator calculates a frame power of a frame having a predetermined width of an input signal data at every predetermined time interval. Instantaneous power maximum value latch and instantaneous power minimum value latch hold and update respective maximum and minimum values of the frame power of the frame at every predetermined time period. A power threshold value decision portion sets and updates a threshold value for power so as to be varied according to the maximum value and difference between the maximum value and the minimum value at every predetermined time period. A discriminator compares the last threshold value obtained'by the power threshold value decision portion with power of a current frame to decide whether the current frame belongs to a speech interval or a non-speech interval.
