Abstract
Abstract Computer-aided speech-recognition circuitry is incorporated in a telephone receiver and programmed to recognize utterances given in response to a request for directory assistance. The information number given is displayed on the face of the receiver and stored for dialing out. An automatic dial out feature is included. The system is dormant until activated by a digit recognition circuit which samples all outgoing numbers dialed and is responsive to the 555-1212 digit sequence or any other digit sequence desired.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
185 words
An information recognition display and dialer for a phone receiver having input and output lines, comprising: a. a speech recognition and storage means connected to the input lines of said phone receiver; b. an activator circuit connected to said speech recognition and storage means responsive to a digit sequence connected to the output line of said phone receiver for activating said speech recognition and storage means; c. a numeric display means connected to said speech recognition and storage means for displaying the digits recognized and stored in said recognition and storage means; d. dialer means connected to said speech recognition and storage means and to the output lines of said phone receiver for delivering dialing pulses to the output lines of said phone receiver corresponding to the digits recognized and stored in said speech recognition and storage means; e. a dialer activator located on said phone receiver connected to said dialer means for initiating a dialout function; f. a dialtone recognition circuit connected to said phone receiver and said dialer activator which prevents the dialer activator from activating said dialer until a dialtone is recognized.
Claim 2
Dependent Claim
185 words
An information recognition display and dialer for a phone receiver having input and output lines, comprising: a. a speech recognition and storage means connected to the input lines of said phone receiver; b. an activator circuit connected to said speech recognition and storage means responsive to a digit sequence connected to the output line of said phone receiver for activating said speech recognition and storage means; c. a numeric display means connected to said speech recognition and storage means for displaying the digits recognized and stored in said recognition and storage means; d. dialer means connected to said speech recognition and storage means and to the output lines of said phone receiver for delivering dialing pulses to the output lines of said phone receiver corresponding to the digits recognized and stored in said speech recognition and storage means; e. a dialer activator located on said phone receiver connected to said dialer means for initiating a dialout function; f. a dialtone recognition circuit connected to said phone receiver and said dialer activator which prevents the dialer activator from activating said dialer until a dialtone is recognized.
