PURPOSE:To execute speech recognition processing by voice data without generating the omission of a leading part by storing input voice data just before a start command is supplied sequentially in a ring buffer, and performing the detection of a voice section and the extraction processing of the voice data by using the input voice data. CONSTITUTION:The input voice data just before a command to instruct the start of the speech recognition processing is inputted is stored in the ring buffer 3 sequentially extending over the several constant number of frames. Therefore, even when the leading part is omitted in the input voice data stored in a data buffer 4, the detection of the start of the voice section can be performed by supplementing an omitted part by the voice data stored in the ring buffer 3, and the data in the voice section can be extracted without defeating the data unexpectedly. In such a way, even when vocalization is started prior to the input of the command to start the speech recognition processing, the vocalization can surely be recognized and processed. |
