Wu Chou, Biing Hwang Juang: Recognition unit model training based on competing word and word string models. Lucent Technologies, Thomas A Restaino, Kenneth M Brown, November 26, 1996: US05579436 (194 worldwide citation)

A system pattern-based speech recognition, e.g., a hidden Markov model (HMM) based speech recognizer using Viterbi scoring. The principle of minimum recognition error rate is applied by the present invention using discriminative training. Various issues related to the special structure of HMMs are p ...

Markov model speech pattern templates are formed for speech analysis systems by analyzing identified speech patterns to generate frame sequences of acoustic feature signals representative thereof. The speech pattern template is produced by iteratively generating succeeding Markov model signal sets s ...

A key-phrase detection and verification method that can be advantageously used to realize understanding of flexible (i.e., unconstrained) speech. A "multiple pass" procedure is applied to a spoken utterance comprising a sequence of words (i.e., a "sentence"). First, a plurality of key-phrases are de ...

A facility is provided for allowing a caller to place a telephone call by merely uttering a label identifying a desired called destination and to charge the telephone call to a particular billing account by merely uttering a label identifying that account. Alternatively, the caller may place the cal ...

Wu Chou, Biing Hwang Juang, Chin Hui Lee, Mazin G Rahim: Discriminative utterance verification for connected digits recognition. Lucent Technologies, April 7, 1998: US05737489 (98 worldwide citation)

In a speech recognition system, a recognition processor receives an unknown utterance signal as input. The recognition processor in response to the unknown utterance signal input accesses a recognition database and scores the utterance signal against recognition models in the recognition database to ...
