摘要

PROBLEM TO BE SOLVED: To provide a telephone conversation recording apparatus, a telephone conversation recording program, a voice recognition server, a voice recognition program, a telephone conversation recording system, and a telephone conversation recording method capable of playing back telephone conversation uplink audio and downlink audio separately and producing recording data of small volume.;SOLUTION: A telephone conversation recording apparatus 1 generates monaural main audio data 61 and sets an isolation bit to which true is set in the monaural main audio data 61 when the level of the downlink audio data is equal to or more than a prescribed value. When a double-talk is detected, the telephone conversation recording apparatus 1 sets a double-talk bit to which true is set in the monaural main audio data 61 so as to produce monaural sub audio data 62. When the double-talk bit is true, a voice recognition server 2 generates uplink audio data and downlink audio data from the monaural main audio data 61 and the monaural sub audio data 62, and outputs the generated data. The voice recognition server 2 outputs monaural main audio data 61 as downlink audio data when the double-talk bit is false and the isolation bit is true, while the server 2 outputs the audio data 61 as uplink audio data when the isolation bit is false.;COPYRIGHT: (C)2013,JPO&INPIT
