Abstract

In one embodiment, the methods and apparatuses detect an original audio signal;detect a sound model wherein the sound model includes a sound parameter; transform the original audio signal based on the parameter whereby forming a transformed audio signal; and compare the transformed audio signal with the original audio signal.

Claims

1. A method comprising:

detecting an original audio signal;

detecting a sound model wherein the sound model includes a sound parameter;

transforming the original audio signal based on the parameter whereby forming a transformed audio signal; and

comparing the transformed audio signal with the original audio signal.

2. The method according to claim 1 further comprising storing the sound model within a profile.

3. The method according to claim 1 further comprising playing back the transformed audio signal.

4. The method according to claim 1 wherein the sound model represents characteristics of a voice.

5. The method according to claim 4 wherein the voice belongs to a public figure.

6. The method according to claim 1 wherein the sound parameter is one of a pitch, speed, formant, and inflection.

7. The method according to claim 1 wherein the comparing further comprises detecting an error with the transformed audio signal.

8. The method according to claim 1 wherein the audio signal has a duration of a period of time.

9. The method according to claim 1 wherein the audio signal comprises a plurality of frames.

10. A method comprising:

selecting a sound model;

displaying text associated with the sound model;

detecting an original audio signal in response to the text; and

transforming the original audio signal based on the sound model and forming a transformed audio signal.

11. The method according to claim 10 further comprising comparing the transformed audio signal with a sound clip wherein the sound clip reflects the text.

12. The method according to claim 11 further comprising scoring the transformed audio signal based on comparing the transformed audio signal with the sound clip.

13. The method according to claim 11 wherein the sound clip originates from a voice of a public figure and wherein the sound model is based on the public figure.

14. The method according to claim 10 wherein the sound model includes a sound parameter.

15. The method according to claim 14 wherein the sound parameter is one of a pitch, speed, formant, and inflection.

16. A method comprising:

detecting an audio signal from a source;

analyzing the audio signal for a short term parameter;

analyzing the audio signal for a long term parameter;

forming a sound model based on the short term parameter and the long term parameter; and

storing the sound model.

17. The method according to claim 16 wherein the source represents a voice of a person.

18. The method according to claim 16 wherein the source is pre-recorded media.

19. The method according to claim 16 wherein the short term parameter includes one of pitch, formant, inflection, and speed.

20. The method according to claim 16 wherein the long term parameter includes one of rhythm and spectral envelope.

21. A system, comprising:

a sound processing module configured for processing incoming audio signals;

an audio profile module configured for storing a parameter associated with a sound model; and

a voice transformation module configures for transforming the incoming audio signals according to the sound model and forming transformed audio signals.

22. The system according to claim 21 further comprising a storage module configured for storing the sound model.

23. The system according to claim 21 further comprising a voice comparison module configured to compare the transformed audio signals with the incoming audio signals based on the sound model.

24. The system according to claim 21 further comprising a voice comparison module configured to compare the transformed audio signals with a source audio signal corresponding with a source of the sound model.

25. A computer-readable medium having computer executable instructions for performing a method comprising:

detecting an original audio signal;

detecting a sound model wherein the sound model includes a sound parameter;

transforming the original audio signal based on the parameter whereby forming a transformed audio signal; and

comparing the transformed audio signal with the original audio signal.
