Claims
- 1. A method of diagnosing voices comprising:
processing a test voice signal using an auditory model; determining at least one voice quality attribute from the test voice signal; comparing the at least one voice quality attribute from the test voice signal with at least one baseline voice quality attribute; and based upon said comparing step, determining at least one measure of voice quality of the test voice signal.
- 2. The method of claim 1, further comprising determining a degree of the measure of voice quality.
- 3. The method of claim 1, wherein the measure of voice quality is at least one of roughness and hoarseness.
- 4. The method of claim 3, wherein the voice quality attributes of the test voice signal include changes in pitch over time and changes in loudness over time.
- 5. The method of claim 4, wherein the voice quality attribute of the test voice signal includes a measure of partial loudness.
- 6. The method of claim 1, wherein the measure of voice quality is breathiness.
- 7. The method of claim 6, wherein the voice quality attribute of the test voice signal includes a measure of low frequency periodic energy.
- 8. The method of claim 6, wherein the voice quality attribute of the test voice signal includes a measure of high frequency aperiodic energy.
- 9. The method of claim 6, wherein the voice quality attribute of the test voice signal includes a measure of partial loudness of a periodic signal portion of the test voice signal.
- 10. The method of claim 6, wherein the voice quality attributes of the test voice signal include a measure of noise in the test voice signal and a measure of partial loudness of the test voice signal.
- 11. A system for diagnosing voices comprising:
means for processing a test voice signal using an auditory model; means for determining at least one voice quality attribute from the test voice signal; means for comparing the at least one voice quality attribute from the test voice signal with at least one baseline voice quality attribute; and means for determining at least one measure of voice quality of the test voice signal based upon said means for comparing.
- 12. The system of claim 11, further comprising means for determining the degree of the measure of voice quality.
- 13. The system of claim 11, wherein the measure of voice quality is at least one of roughness and hoarseness.
- 14. The system of claim 13, wherein the voice quality attributes of the test voice signal include changes in pitch over time and changes in loudness over time.
- 15. The system of claim 14, wherein the voice quality attribute of the test voice signal includes a measure of partial loudness.
- 16. The system of claim 11, wherein the measure of voice quality is breathiness.
- 17. The system of claim 16, wherein the voice quality attribute of the test voice signal includes a measure of low frequency periodic energy.
- 18. The system of claim 16, wherein the voice quality attribute of the test voice signal includes a measure of high frequency aperiodic energy.
- 19. The system of claim 16, wherein the voice quality attribute of the test voice signal includes a measure of partial loudness of a periodic signal portion of the test voice signal.
- 20. The system of claim 16, wherein the voice quality attributes of the test voice signal include a measure of noise in the test voice signal and a measure of partial loudness of the test voice signal.
- 21. A machine readable storage, having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the steps of:
processing a test voice signal using an auditory model; determining at least one voice quality attribute from the test voice signal; comparing the at least one voice quality attribute from the test voice signal with at least one baseline voice quality attribute; and based upon said comparing step, determining at least one measure of voice quality of the test voice signal.
- 22. The machine readable storage of claim 21, further comprising determining the degree of the measure of voice quality.
- 23. The machine readable storage of claim 21, wherein the measure of voice quality is at least one of roughness and hoarseness.
- 24. The machine readable storage of claim 23, wherein the voice quality attributes of the test voice signal include changes in pitch over time and changes in loudness over time.
- 25. The machine readable storage of claim 24, wherein the voice quality attribute of the test voice signal includes a measure of partial loudness.
- 26. The machine readable storage of claim 21, wherein the measure of voice quality is breathiness.
- 27. The machine readable storage of claim 26, wherein the voice quality attribute of the test signal includes a measure of low frequency periodic energy.
- 28. The machine readable storage of claim 26, wherein the voice quality attribute of the test voice signal includes a measure of high frequency aperiodic energy.
- 29. The machine readable storage of claim 26, wherein the voice quality attribute of the test voice signal includes a measure of partial loudness of a periodic signal portion of the test voice signal.
- 30. The machine readable storage of claim 26, wherein the voice quality attributes of the test voice signal include a measure of noise in the test voice signal and a measure of partial loudness of the test voice signal.
