PROBLEM TO BE SOLVED: To provide a convenient acoustic echo canceller (AEC) evaluation method not requiring a special device, and to provide a medium for use therein. SOLUTION: The acoustic echo canceller is evaluated by a step of preparing near end data, remote end data, and synthetic voice data compounding near end data and echo voice data obtained from the remote end data through a predetermined acoustic system as temporally synchronized data. Consequently, a convenient AEC evaluation method not requiring a special device for evaluation and a medium for use therein are obtained. COPYRIGHT: (C)2007,JPO&INPIT |
