Abstract

Telephone apparatus in which a call may be made in response to utterances of a user by speech recognition without manually dialing a telephone number. The telephone apparatus includes a storage device for storing a set of parameters corresponding to an expected speech signal, which are used for recognizing the user'"'"'s subsequent utterance and/or for indicating differences between the utterance and the stored signal. The telephone apparatus further includes a storage device for storing the speech signal so that the stored speech signal can be reproduced. The reproduced speech signal is used to confirm the stored speech signal. The stored speech signal may be reproduced in response to a user'"'"'s key operation when the telephone apparatus is in a confirmation mode and in response to a user'"'"'s utterance when the telephone apparatus is in a registration or voice calling mode.

Claims

1. Telephone apparatus, comprising:

first means for registering one or more predetermined numbers of data each corresponding to a telephone dial number prior to a user'"'"'s utterance;

second means for registering one or more digital speech signals each corresponding to a telephone dial number prior to said user'"'"'s utterance;

means for providing one or more telephone dial numbers;

means, coupled to said providing means, for generating a digital speech signal corresponding to a provided telephone dial number in response to said user'"'"'s utterance;

means, coupled to said generating means, for extracting a predetermined number of data corresponding to a generated digital speech signal;

means, coupled to said extracting means, for storing an extracted predetermined number of data;

means, coupled to said first registering means and said storing means, for comparing said extracted predetermined number of data to each of one or more registered predetermined numbers of data;

means, coupled to said generating means and said second registering means, for producing a speech signal associated with a registered digital speech signal for confirming whether said generated digital speech signal is substantially identical to said registered digital speech signal; and

means, coupled to the comparing means, for automatically originating a telephone call to a telephone dial number, whenever said extracted predetermined number of data is substantially identical to said registered predetermined number of data corresponding to said retrieved telephone dial number.

2. The apparatus of claim 1, further comprising means for indicating to the user whether the user'"'"'s utterance corresponding to said registered digital speech signal has been received.

3. The apparatus of claim 1, further comprising means, coupled to said second registering means, for generating audible sounds corresponding to said registered digital speech signal.

4. The apparatus of claim 1, further comprising means, coupled to said second registering means, for visually displaying an image corresponding to said registered digital speech signal.

5. The apparatus of claim 2, further comprising means for activating said indicating means.

6. Telephone apparatus, comprising:

first means for registering one or more predetermined number of data each corresponding to a telephone dial number prior to a user'"'"'s utterance;

second means for registering one or more speech signals each corresponding to a telephone dial number prior to said user'"'"'s utterance;

means for providing one or more telephone dial numbers;

means, coupled to said providing means, for generating a speech signal corresponding to a provided telephone dial number in response to said user'"'"'s utterance;

means, coupled to the generating means, for extracting a predetermined number of data corresponding to a generated speech signal;

means, coupled to the extracting means, for storing an extracted predetermined number of data;

means, coupled to said first registering means and said storing means, for comparing said extracted predetermined number of data to each of one or more registered predetermined numbers of data;

means, coupled to said second registering means, for reproducing a registered speech signal; and

means, coupled to the comparing means, for automatically originating a telephone call to a telephone dial number whenever said extracted predetermined number of data is substantially identical to said registered predetermined number of data corresponding to said retrieved telephone dial number.

7. The apparatus of claim 6, wherein said means for providing telephone dial numbers includes means for providing numerical data.

8. The apparatus of claim 6, further comprising means, coupled to said speech signal generating means, for storing the speech signal, wherein said speech signal generating means includes:

means for converting said user'"'"'s utterance to an analog signal;

means for converting the analog signal to a digital signal; and

means for storing said digital signal in said speech signal storing means.

9. The apparatus of claim 6, further comprising means, coupled to the second registering means, for converting said registered speech signal to an analog value.

10. The apparatus of claim 6, further comprising means, coupled to the generating means, for providing a signal having a set of predetermined frequencies corresponding to said generated speech signal.

11. The apparatus of claim 6, further comprising means, coupled to the generating means, for providing a set of normalized time values corresponding to said generated speech signal.

12. The apparatus of claim 6, further comprising means, coupled to the generating means, for providing a predetermined number of discrete values corresponding to said generated speech signal.

13. The apparatus of claim 6, further comprising means, coupled to said reproducing means, for activating the reproducing means.

14. The apparatus of claim 6, wherein the reproducing means includes means, coupled to the generating means, for reproducing said registered speech signal whenever said corresponding speech signal is generated.

15. The apparatus of claim 6, further comprising:

third means for registering one or more telephone dial numbers prior to said user'"'"'s utterance; and

means, coupled to said third registering means and said means for providing one or more telephone dial numbers, for comparing said provided telephone dial number to each of the one or more registered telephone dial numbers.

16. The apparatus of claim 12, further comprising means, coupled to the generating means, for sampling said generated speech signal to provide said predetermined number of discrete values.

17. The apparatus of claim 13, further comprising means, coupled to the providing means, for displaying said telephone dial number.

18. The apparatus of claim 14, further comprising means, coupled to the providing means, for displaying said telephone dial number.

19. The apparatus of claim 17, wherein said displaying means includes means, coupled to the means for activating the reproducing means, for displaying said telephone dial number corresponding to a reproduced speech signal whenever the reproducing means is activated.

20. The apparatus of claim 18, wherein said displaying means includes means, coupled to the reproducing means, for displaying said telephone dial number corresponding to a reproduced registered speech signal whenever said corresponding speech signal is generated.

21. Telephone apparatus, comprising:

first means for registering on or more predetermined numbers of data each corresponding to a telephone dial number prior to a user'"'"'s utterance;

second means for registering one or more speech signals each corresponding to a telephone dial number prior to said user'"'"'s utterance;
