Abstract:
1. A computer readable medium storing a computer program to perform method steps for execution by a processor, the method steps comprising: generating a synthetic waveform for each of N textual transcriptions of an original waveform, wherein N is greater than 1 and the N textual transcriptions are generated by a speech recognition system and represent N-best textual transcription hypotheses of the original waveform; for each synthetic waveform, comparing scores based on the overall distance measure between the synthetic waveform and the original waveform, an acoustic model score of a corresponding textual transcription of the synthetic waveform, and a language model score of the corresponding textual transcription to determine a corresponding one of the N-best textual transcriptions; and selecting for output the determined N-best textual transcription.
