  • Patent number: 6975983
    Abstract: A system is disclosed for generating a modified data structure defining modified grammar rules for the recognition of a natural language input with pauses in which grammar rules for recognition of a natural language are analysed to identify positions in the grammar rules at which pauses can occur in the natural language. A modified data structure is generated defining the modified grammar rules in dependence upon the analysis. The modified data structure is used to improve the accuracy of recognition of a natural language input with pauses. Where the natural language input is used in conjunction with a second modality input, the analysis is performed to identify the positions of pauses in dependence upon the second modality inputs.

  • Patent number: 6823308
    Abstract: A speech recognition method for use in a multimodal input system comprises receiving a multimodal input comprising digitized speech as a first modality input and data in at least one further modality input. Features in the speech and in the data in at least one further modality are identified. The identified features in the speech and in the data are used in the recognition of words by comparing the identified features with states in models for the words. The models have states for the recognition of speech and for words having features in at least one further modality associated with the words, the models also have states for the recognition of events in the further modality or each further modality.
