When a speech sound of at least a predetermined sound pressure is externally input while a time measurement is not being performed, a time measuring circuit starts a time measurement responsive to a signal from a speech detector. When another speech sound of at least a predetermined sound pressure is externally input while a time measurement is being performed by the time measuring circuit, a measurement time measured by the time measuring circuit at this moment is stored in a time information memory. After a predetermined time has elapsed, if a speech recognition circuit recognizes that the externally input speech sound is a "stop" command, the time measurement operation performed by the time measuring circuit is stopped, and the time information stored in the time information memory is read out and displayed as measurement time information on a display unit.

DETAILED DESCRIPTION The present invention has been made in consideration of the above conventional problem and has as its object to provide a speech recognition apparatus capable of eliminating a time difference upon speech recognition to perform a correct operation.
In order to achieve the above object of the present invention, there is provided a speech recognition apparatus comprising: speech input means for externally inputting a speech; first control means, connected to the speech input means, for performing a predetermined operation when the speech is input; speech recognizing means, connected to the speech input means, for recognizing the input speech; and second control means, connected to the speech recognizing means, for performing an operation different from the predetermined operation performed by said first control means on the basis of a recognition result obtained by the speech recognizing means.
With the above arrangement, the present invention has an effect of correctly performing time measurement or data search in accordance with speech recognition.
