Abstract:
A method for cross-speaker speech recognition for telecommunication systems, the method comprising:(a) receiving incoming speech; (b) generating a phonetic representation of the incoming speech with a first speaker-independent model having an unconstrained grammar with a plurality of phonemes, in which any second phoneme of the plurality of phonemes may occur following any first phoneme of the plurality of phonemes; (c) determining a transcription parameter as a first correspondence of the incoming speech to the first speaker-independent model; (d) selecting a first phoneme pattern, from a plurality of phoneme patterns, utilizing a second speaker-independent model having a grammar constrained by the plurality of phoneme patterns; (e) determining a recognition parameter as a second correspondence of the incoming speech to the first phoneme pattern; and (f) determining whether the input speech matches the first phoneme pattern based upon a third correspondence of the transcription parameter with the recognition parameter in accordance with a predetermined criterion.
