摘要：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.
