PURPOSE:To obtain stable recognition performance even in environment wherein the distance and direction between the voicing windpipe and a microphone change and background noise environment changes. CONSTITUTION:Voices which are collected through plural microphones at the same time are inputted from input terminals 101, 102, and 103 and passed through voice analysis parts 104, 105, and 106 and voice section detection part 107, 108, and 109, and comparison pattern memory parts 110, 111, and 112 are referred to, so that voice identification parts 113, 114, and 115 recognize them independently of one another. A total decision part 116 totally decides the results of the independent recognition and identification auxiliary information (identification accuracy, start and end times of voice, and signal-to-noise ratio) and outputs the final recognition result to an output terminal 117. |
