Abstract:
1. A voice recognition apparatus comprising: an input unit configured to input a voice; a voice detecting unit configured to detect the voice after starting a voice input waiting state in which a voice recognition is enabled and the apparatus waits for input of the voice; a voice recognizing unit configured to recognize the voice; a timer unit configured to count an elapsed time Ts from a start of the voice input waiting state; an output unit configured to output an informative sound which prompts for input of the voice in response to the elapsed time Ts reaching a preset output set time; and a control unit configured to control the output unit (1) to output the informative sound according to at least one of a reference volume, a reference frequency, or a reference output duration in response to the elapsed time Ts reaching the output set time if the voice detecting unit does not detect the voice during the voice input waiting state, and (2) to output the informative sound according to at least one of a lower volume than the reference volume, a shifted frequency relative to the reference frequency, or a shorter output duration relative to the reference output duration if the voice detecting unit detects the voice before the elapsed time reaches the output set time, wherein the lower volume, the shifted frequency, and the shorter output duration are continuous functions of a value of Ts at a time that the voice detecting unit detects the voice.
