Abstract
An interactive robot capable of speech recognition includes a sound-source-direction estimating unit that estimates a direction of a sound source for target voices which are required to undergo speech recognition; a moving unit that moves the interactive robot in the sound-source direction; a target-voice acquiring unit that acquires the target voices at a position after moving; and a speech recognizing unit that performs speech recognition of the target voices.
Claims18
An interactive robot capable of speech recognition, comprising:
- a sound-source-direction estimating unit that estimates a direction of a sound source for target voices which are required to undergo speech recognition;
- a moving unit that moves the interactive robot in the sound-source direction;
- a target-voice acquiring unit that acquires the target voices at a position after moving;
- and
- a speech recognizing unit that performs speech recognition of the target voices.
A speech recognition method for an interactive robot capable of speech recognition, the method comprising:
- estimating a direction of the sound source of target voices which are required to undergo speech recognition;
- moving the interactive robot in the direction of the sound source;
- acquiring the target voices when the interactive robot is located at a position after moving;
- and
- performing the speech recognition of the target voices.
A computer program product having a computer readable medium including programmed instructions for performing speech recognition processing on an interactive robot capable of speech recognition, wherein the instructions, when executed by a computer, cause the computer to perform:
- estimating a direction of the sound source of target voices which are required to undergo speech recognition;
- moving the interactive robot in the direction of the sound source;
- acquiring the target voices when the interactive robot is located-at a position after moving;
- and
- performing the speech recognition of the target voices.
