Title: Double-talk detection method and apparatus, and echo canceller
Inventor: ARIYAMA YOSHIHIRO
IPC: H04B3/23
Filed: 2001-09-27
Abstract: PROBLEM TO BE SOLVED: To achieve accurate echo cancellation characteristics by speedily and accurately judging a double-talk state. SOLUTION: The double-talk detection apparatus comprises an adaptive filter section 104 for analyzing the characteristics of an echo path and synthesizing a pseudo echo, and a double-talk decision section 109 for deciding the double-talk state based on the rate decision information of a variable rate voice codec section 101. Then, only when the rate decision result of a decoder at the variable rate voice codec section 101 is a high rate equivalent to a section having sound, and the rate decision result of an encoder is a low rate equivalent to a section without any sound, it is decided as a single talk state and the adaptive filter section 104 is updated. Otherwise, it is decided as a double-talk state, and the updating operation of the adaptive filter section 104 is stopped, thus achieving accurate echo cancellation characteristics.  Along with the rate decision information, the double-talk state may be decided based on the rate decision information and the average power of each signal of a remote end, a near end, and a residual.
