Speech recognition apparatus with means for preventing errors due to delay in speech recognition
First Claim
1. A speech recognition apparatus comprising:
- time measuring means for counting reference signals to obtain measurement time information;
display means for displaying the measurement time information obtained by the time measuring means;
speech detecting means for detecting speech externally input;
measurement start control means for supplying a measurement start signal to the time measuring means in response to the detection of speech by the speech detecting means, during an interval when the time measuring means is not performing a measurement operation for obtaining the measurement time information;
measurement time information-storing means for storing the measurement time information obtained by the time measuring means in response to the detection of speech by the speech detecting means, during an interval when the time measuring means is performing the measurement operation under the control of the measurement start control means;
speech recognizing means for recognizing that the speech externally input to the speech detecting means indicates a stop command for stopping the measurement operation performed by the time measuring means; and
display control means for stopping the measurement operation performed by the time measuring means in response to the recognition of an indication of a stop command by the speech recognizing means, and for causing the display means to display the measurement time information stored in the measurement time information-storing means.

Abstract
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.

7. A speech recognition apparatus comprising:
-
item data memory means for storing a large amount of item data including a plurality of characters; read control means for sequentially reading the item data out of the item data memory means at predetermined time intervals; data display means for sequentially switching and displaying the item data read out by the read control means; speech detecting means for detecting speech externally input; stop control means for stopping a reading operation performed by the read control means in response to the detection by the speech detecting means when the read control means is in an operating state; speech recognizing means for recognizing whether or not the speech externally input to the speech detecting means indicates a stop command for stopping a reading operation performed by the read control means; and restart means for causing the read control means to restart a reading operation of the read control means if the speech recognizing means recognizes that the externally-input speech does not indicate the stop command. - View Dependent Claims (8, 9)

10. A speech recognition apparatus comprising:
-
speech detecting means for detecting speech externally input; speech recognizing means for recognizing whether the externally-input speech indicates a start command for starting a time measurement operation or a stop command for stopping the time measurement operation; first time-measuring means (C) for starting the time measurement operation if the speech recognizing means recognizes that the externally-input speech indicates the start command, and for stopping the time measurement operation if the speech recognizing means recognizes that the externally-input speech indicates the stop command; second time-measuring means (C) for measuring time from the detection of the externally-input speech by the speech detection means to the start of the time measurement operation, so as to obtain time data; and display means for displaying time which is obtained by adding time corresponding to the time data obtained by the second time-measuring means to measurement time obtained by the first time-measuring means. - View Dependent Claims (11, 12, 13, 14, 15)

16. A speech recognition apparatus comprising:
-
item data memory means for storing a large amount of item data including a plurality of characters; read control means for sequentially reading the time data out of the item data memory means at predetermined time intervals; data display means for sequentially switching and displaying the item data read out by the read control means; speech detecting means for detecting speech externally input; speech recognizing means for recognizing whether or not the speech externally input to the speech detecting means indicates a stop command for stopping a reading operation performed by the read control means; and stop control means for stopping a reading operation performed by the read control means when the speech recognizing means detects speech indicating the stop command when the read control means is in an operating state, said stop control means including display control means for switching the data display means to show the item data previously shown on the data display means, when the speech detecting means detects the externally-input speech. - View Dependent Claims (17)
