REVERBERANT ENVIRONMENT DETERMINATION DEVICE, REVERBERANT ENVIRONMENT DETERMINATION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a reverberant environment determination device for enabling even an operator who is not familiar with voice recording to determine a reverberant environment.;SOLUTION: The reverberant environment determination device comprises: an acoustic model recording part 140 for recording acoustic models created from recorded voices in different reverberant environments and model names; a reverberant knowledge recording part 160 for recording the model names and the reverberant environments; a read-out text recording part 150 for recording a read-out text; a voice recognition part 110 for voice-recognizing an input voice by using each acoustic model of the acoustic model recording part, and for generating an acoustic model-categorized recognition result including the model name and a text of a voice recognition resu a recognition rate calculation part 120 for generating an acoustic model-categorized recognition rate including the model name and a recognition rate from the acoustic model-categorized recognition result by using the read-out text of the read-out text recording part; and a reverberation determination part 130 for generating, as a determination result, the reverberant environment of the reverberant knowledge including the model name of the acoustic model which has output the highest recognition rate among the acoustic model-categorized recognition rates by using the reverberant knowledge recording part.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
