Abstract

A speech registration/recognition processing section is responsive to a speech input signal to be registered or recognized from a microphone to selectively subject the speech input signal to a registration or a recognition processing, in which upon the registration processing the speech input signal is allowed to be stored as recognition data and upon the recognition processing the speech input signal is compared to the recognition data stored. A speech record/reproduction processing section is responsive to the speech input signal from the microphone to subject the speech input signal to a record/reproduction processing, in which upon the record processing the speech input signal is recorded as a record signal and upon the reproduction processing the record signal is delivered as a reproduction signal. A speaker is supplied with the reproduction signal. A control section is provided, in accordance with a registration or a recognition mode designation signal, for setting the speech registration/recognition processing section to the registration or the recognition processing and for setting the speech record/reproduction processing section to the record or the reproduction processing corresponding to the registration or the recognition processing at which the speech registration/recognition processing section is placed.

Claims

1. A telephone apparatus with a speech recognition function comprising:

microphone means for producing speech input signals of various users, to be registered or recognized;

speech registration/recognition processing means, responsive to a speech input signal from the microphone means, wherein said speech registration/recognition processing means is manually selectable so as to subject the speech input signal to either a registration or a recognition processing, in which upon the registration processing, the speech input signal is stored as recognition data and upon recognition processing, the speech input signal is compared to the recognition data which as been stored;

speech record/reproduction processing means, responsive to a speech input signal from the microphone means to subject this speech input signal to a record/reproduction processing, in which, upon the record processing, this speech input signal is recorded as a record signal and, upon the reproduction processing, the record signal is delivered as a reproduction signal in a given user voice, which has been pre-registered, in advance;

speaker means to which the reproduction signal is supplied;

mode designation means for delivering registration or a recognition mode designation signal;

control means, in accordance with the registration or the recognition mode designation signal, for setting the speech registration/recognition processing means to the registration or the recognition processing mode and for setting the speech record/reproduction processing means to the record or the reproduction processing mode corresponding to the registration or the recognition processing mode in which the speech registration/recognition processing means is placed;

telephone dial number input means for inputting a telephone dial number corresponding to the produced speech input signals in the registration processing; and

call origination means responsive to a speech input signal inputted in the recognition processing for originating a call on the basis of a telephone dial number corresponding to a speech input signal registered in the registration processing, in the event that the speech input signal inputted in the recognition processing is identical with the registered speech input signal.

2. The apparatus according to claim 1, wherein the speech record/reproduction processing means delivers the reproduction signal before the call origination means originates the call.

3. The apparatus according to claim 2, further comprising:

display means responsive to the speech registration/recognition processing means for displaying a telephone dial number corresponding to the registered speech input signal.

4. The apparatus according to claim 3, wherein the display means displays the telephone dial number before the call origination means originates the call.

5. A radio telephone apparatus with a speech recognition function, comprising:

microphone means for producing speech input signals of various users, to be registered or recognized;

speech registration/recognition processing means, responsive to a speech input signal from the microphone means, wherein said speech registration/recognition processing means is manually selectable so as to subject this speech input signal to either a registration or a recognition processing, in which upon the registration processing, the speech input signal is stored as recognition data and upon the recognition processing, the speech input signal is compared to the recognition data stored;

speech record/reproduction processing means, responsive to a speech input signal from the microphone means to subject this speech input signal to a record/reproduction processing, in which, upon the record processing, this speech input signal is recorded as a record signal, and upon the reproduction processing, the record signal is delivered as a reproduction signal in a given user voice, which has been pre-registered, in advance;

speaker means to which the reproduction signal is supplied;

mode designation means for delivering a registration or a recognition mode designation signal;

control means, in accordance with the registration or the recognition mode designation signal, for setting the speech registration/recognition processing means to the registration or the recognition processing mode and for setting the speech record/reproduction processing means to the record or the reproduction processing mode corresponding to the registration or the recognition processing mode in which the speech registration/recognition processing means is placed;

telephone dial number input means for inputting a telephone dial number corresponding to the produced speech input signals in the registration processing; and

establishing means responsive to a speech input signal inputted in the recognition processing, for establishing a radio link with another apparatus on the basis of a telephone dial number corresponding to a speech input signal registered in the registration processing in the event that the speech input in the recognition processing is identical with the registered speech input signal.

6. The apparatus according to claim 5, wherein the speech record/reproduction processing means delivers the reproduction signal before the radio link is established.

7. The apparatus according to claim 6, further comprising display means responsive to the speech registration/recognition processing means for displaying a telephone dial number corresponding to the registered speech input signal.

8. The apparatus according to claim 7, wherein the display means displays the telephone dial number before the radio link is established.
