Abstract

A speech recognition control device has a plurality of microphones placed at different positions, a speech transmission control unit, and a speech recognition execution control unit. The speech transmission control unit stores data based on the speeches which are input from the microphones and time data related to ranks among the microphones, assigns ranks to the plurality of microphones using the time data based on a preset condition, and transmits a speech data signal corresponding to the microphone to the speech recognition execution control unit in the order of the ranks. The speech recognition execution control unit executes the speech recognition process according to the order of the speech data signals transmitted from the speech transmission control unit.

Claims

1. A speech recognition control device having a speech recognition execution control unit that executes a speech recognition process to recognize that an input speech data signal is an execution command and executes the execution command, the speech recognition control device comprising:

a plurality of microphones placed at positions different from each other; and

a speech transmission control unit that stores data based on a speech which is input from each of the microphones and time data related to ranks among the microphones, that assigns ranks to the plurality of microphones using the time data based on a preset condition, and that transmits speech data signals corresponding to the microphones to the speech recognition execution control unit in an order of the ranks, wherein

the speech recognition execution control unit executes the speech recognition process according to an order of the speech data signals transmitted from the speech transmission control unit.

2. The speech recognition control device according to claim 1, wherein

the condition is that, when speeches are simultaneously input from the plurality of microphones, the speech transmission control unit assigns the ranks to the plurality of microphones based on time data that indicate an order of completion of the speeches.

3. The speech recognition control device according to claim 1, further comprising:

a plurality of operation units that are placed at periphery of the microphones, that obtain inputs of commands of start of speech recognition by an operation of a user, and that transmit a command signal indicating the input of the command to the speech transmission control unit, wherein

the condition is that the speech transmission control unit assigns the ranks to the plurality of microphones based on time data that indicate an order of reception of the command signals from the plurality of operation units.
