ABSTRACT:
A method and apparatus (100) for updating a voice tag comprising N stored voice tag phoneme sequences includes a function (110) for determining (205) an accepted stored voice tag phoneme sequence for an utterance, a function (140) for extracting(210) a current set of M phoneme sequences having highest likelihoods of representing the utterance, a function (160) for updating (215) a reference histogram associated with the accepted voice tag, and a function (160) for updating (225) the voice tag with N selected phoneme sequences that are selected from the current set of M phoneme sequences and the set of N voice tag phoneme sequences, wherein the N selected phoneme sequences have phoneme histograms most closely matching the reference histogram. The method and apparatus (100) also generates a voice tag using some functions (110, 140, 160) that are common with the method and apparatus to update the voice tag, such as the extracting (410) of the current set of M phoneme sequences.
