Abstract

A system and method of adapting a speech system includes the steps of: receiving confirmation of a phonetic transcription of one or more names, receiving confirmation of a selected stored text result, and storing the phonetic transcription with the selected stored text result using an automatic speech recognition (ASR) system, a text-to-speech (TTS) system, or both.

Claims

1. A method of adapting speech systems, comprising the steps of:

a) receiving confirmation of a phonetic transcription of one or more names;

b) receiving confirmation of a selected stored text result; and

c) storing the phonetic transcription with the selected stored text result using an automatic speech recognition (ASR) system, a text-to-speech (TTS) system, or both.

2. The method of claim 1, wherein the phonetic transcription is confirmed by the user, the ASR system, or the TTS system.

3. The method of claim 1, wherein the one or more names further comprises a name of a person, a song, a website, a file, a phone number, or a street address.

4. The method of claim 1, further comprising the step of initiating steps (a)-(c) when the output from the ASR system, the TTS system, or both falls below a predetermined confidence threshold.

5. The method of claim 1, wherein the ASR system is used with a remote speech recognition system accessed via a handheld wireless device.

6. A method of adapting speech systems, comprising the steps of:

a) receiving a spoken name at an automatic speech recognition (ASR) system from a user via a vehicle microphone;

b) converting the spoken name into a phonetic transcription using the ASR system;

c) presenting the phonetic transcription to the user;

d) receiving confirmation at the vehicle that the phonetic transcription is accurate;

e) selecting text representing the spoken name; and

f) storing the phonetic transcription using the ASR system, a text-to-speech (TTS) system, or both.

7. The method of claim 6, wherein a text interpretation is generated from the confirmed phonetic transcription in step (d).

8. The method of claim 6, wherein the phonetic transcription is confirmed by the user, the ASR system, or the TTS system.

9. The method of claim 6, wherein the spoken name further comprises a name of a person, a song, a website, a file, a phone number, or a street address.

10. The method of claim 6, further comprising the step of initiating steps (a)-(f) when the output from the ASR system, the TTS system, or both falls below a predetermined confidence threshold.

11. The method of claim 6, wherein the text in step (e) is selected through comparison of the confirmed phonetic transcription in step (d) with phonetic transcriptions of stored text.

12. The method of claim 7, wherein the text in step (e) is selected through comparison of the text interpretation with stored text.

13. The method of claim 6, wherein the user confirms the selected text result in step (e).

14. The method of claim 6, wherein the stored phonetic transcription in step (f) is stored in place of a previously stored phonetic transcription.

15. The method of claim 6, wherein a phonetic interpretation is generated from the selected text in step (e), and wherein the phonetic interpretation is compared with the confirmed phonetic transcription in step (d).

16. A method of adapting speech systems, comprising the steps of:

a) receiving a spoken phonebook entry at an automatic speech recognition (ASR) system from a user via a vehicle microphone;

b) converting the spoken phonebook entry into a phonetic transcription using the ASR system;

c) presenting the phonetic transcription to the user;

d) receiving confirmation at the vehicle that the phonetic transcription is accurate;

e) selecting text representing the spoken phonebook entry; and

f) storing the phonetic transcription using the ASR system, a text-to-speech (TTS) system, or both.

17. The method of claim 16, wherein a text interpretation is generated from the confirmed phonetic transcription in step (d).

18. The method of claim 16, wherein the text in step (e) is selected through comparison of the confirmed phonetic transcription in step (d) with phonetic transcriptions of stored text.

19. The method of claim 17, wherein the text in step (e) is accessed through comparison of the text interpretation with the stored text.

20. The method of claim 16, wherein the user confirms the selected stored text result in step (e).
