Vocal timing indicator device for use in voice recognition
First Claim
1. In a voice recognition system which recognizes the vocal utterances spoken by an individual into a microphone by converting the voice utterances into electrical signals, said electrical signals being further converted into a plurality of characteristics which are compared by a data processing device to stored characteristics, the improvement comprising:
- means responsive to a signal from said data processing device to provide a timing signal,means responsive to said timing signal for signalling to said individual a time start when vocal utterances are to be made into said microphone, andmeans responsive to said signalling means for generating a control signal for activating said data processing device at a time during which or slightly after a predetermined time period, the time start following which said vocal utterances are to be made and the time when said data processing device is activated being selected to reduce the stand-by time of said data processing device.

Abstract
A vocal timing indicator for use in voice recognition systems. The timing indicator provides a visual or audible signal to a user to mark the beginning of the time period in which the user is to speak into the microphone associated with the system, thereby ensuring that the proper input signals are used by the system to determine speaker identity or to assist in the recognition of the words uttered.

5. In a voice recognition system which recognizes the vocal utterances spoken by an individual into a microphone by converting the voice utterances into electrical signals, said electrical signals being transmitted over a line further converted into a plurality of characteristics which are compared by a data processing device to stored characteristics, the improvement comprising:
-
distributing means for receiving said electrical signals prior to transmission over said line, means responsive to a signal from said data processing device to provide a timing signal, means responsive to said timing signal for signaling to said individual over said communications line via said distributing means a time start when vocal utterances are to be made into said microphone, and means responsive to said signaling means for generating a control signal for activating said data processing device at a time during or slightly after a predetermined time period, the time start following which said vocal utterances are to be made and the time when said data processing device is activated being selected to reduce the standby-time of said data processing device.
