Abstract:     System and methods for analyzing a vocal performance by automatically critiquing pitch, rhythm and pronunciation or diction of a singer in accordance with pre-programmed criteria. In one aspect, a method for analyzing a vocal performance comprises the steps of capturing the acoustic utterances of a user's vocal performance (singing a song); extracting pitch information from each frame of the acoustic utterances; extracting phonetic information from each frame of the acoustic utterances; combining the extracted pitch information and phonetic information of corresponding frames to generate an encoded representation of the current vocal performance; comparing the encoded representation of the current vocal performance with an encoded reference vocal performance (or the same user or a different person) having pitch and phonetic information associated therewith to determine if a variation between either pitch information, the phonetic information, or both, of the encoded current vocal performance and of the encoded reference vocal performance is within a predetermined, user-specified tolerance; and critiquing the user's current vocal performance if the variation is determined to exceed the predetermined tolerance.

First Claim:
Show all 26 claims
What is claimed is:     1. A system for analyzing a vocal performance, comprising:
  • means for receiving input utterances corresponding to a current vocal performance of a user;
  • means for extracting pitch information from each frame of said input utterances of said current vocal performance;
  • means for extracting phonetic information from each frame of said input utterances of said current vocal performance;
  • means for combining said pitch information and said phonetic information of corresponding frames to generate an encoded representation of said current vocal performance; and
  • means for outputting said encoded representation of said current vocal performance.
