  • Discriminative language modeling for automatic speech recognition with a weak acoustic model and distributed training
    Patent number: 8965763
    Abstract: Training data from a plurality of utterance-to-text-string mappings of an automatic speech recognition (ASR) system may be selected. Parameters of the ASR system that characterize the utterances and their respective mappings may be determined through application of a first acoustic model and a language model. A second acoustic model and the language model may be applied to the selected training data utterances to determine a second set of utterance-to-text-string mappings. The first set of utterance-to-text-string mappings may be compared to the second set of utterance-to-text-string mappings, and the parameters of the ASR system may be updated based on the comparison.
