ACOUSTIC MODEL ADAPTATION PROCESSING METHOD, ACOUSTIC MODEL ADAPTATION PROCESSING DEVICE, ACOUSTIC MODEL ADAPTATION PROCESSING PROGRAM, AND RECORDNG MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an acoustic model adaptation processing method and device for executing acoustic model adaptation processing in a short period of time, without using an expensive device. SOLUTION: Reproduced voice data in which a synchronous signal is imparted to the front end and the rear end of learning voice data are created, and the reproduced voice data are recorded through a path for adaptation processing. By using the synchronous signal from the recorded voice data which are recorded, a part corresponding to the learning voice data is cut out. By the recorded voice data which are cut out, adaptation processing is performed on an acoustic model before adaptation processing, and the acoustic model is created after the adaptation processing.
