  • Patent number: 7983911
    Abstract: The invention relates to a speech recognition process implemented in at least one terminal (114), the speech recognition process using a language model (311), comprising the following steps: detection (502) of at least one unrecognized expression in one of the terminals; recording (503) in the terminal of data representative of the unrecognized expression (309); transmission (603) by the terminal of the recorded data to a remote server (116); analysis, (803) at the level of the remote server, of the data and generation (805) of information for correcting the said language model taking account of at least one part of the unrecognized expression; and transmission (806) from the server to at least one terminal (114, 117, 118) of the correcting information, so as to allow future recognition of at least certain of the unrecognized expressions. The invention also relates to corresponding modules, devices (102) and a remote server (116).

  • Publication number: 20070038451
    Abstract: A voice recognition method includes: representing a vocabulary translated into a Markov network; decoding by means of a Viterbi algorithm; and pruning explored solutions. The vocabulary is described in a tree made up of arcs and of nodes, between which transcriptions are defined that describe phonetic units used by a language model. The Markov network is constructed dynamically at least in part by means of Markov sub-units.

  • Publication number: 20050102142
    Abstract: The invention concerns a voice recognition method implemented in at least a terminal, the voice recognition method using a language model, comprising the following steps: detecting at least a non-recognised expression in one of the terminals; recording in the terminal data representing the non-recognised expression; transmission by the terminal of the recorded data to a remote server; analysis, at the remote server, of said data and generation of data for correcting said language model taking into account at least part of the non-recognised expressions; and transmitting from the server to at least a terminal correction data, so as to enable subsequent recognition of at least some of the non-recognised expressions. The invention also concerns corresponding modules, devices and remote server.

  • Publication number: 20040034519
    Abstract: The invention relates to a voice recognition process, comprising a step of voice recognition taking into account at least one grammatical language model (310) and implementing a decoding algorithm intended for identifying a set of words on the basis of a set of voice samples (201), said language model being associated with at least one dynamically developed finite or infinite state automaton (313).

  • Publication number: 20030105632
    Abstract: The invention relates to a voice recognition process comprising a step (601) of acoustic processing of voice samples (201) and a step (602) of determination of a command intended to be applied to at least one device, and in that said steps of acoustic processing and of determination of a command use a single representation (309) in memory (305) of a language model.

  • Patent number: 6205922
    Abstract: A reversible printing blanket to be used with offset printing machines. The reversible printing blanket has two opposing lithographic printing faces. The blanket comprises a first external lithographic layer providing a first printing face, a second external lithographic layer providing a second printing face, and at least one compressible layer between the lithographic layers. Such reversible printing blanket allows impressions to be made by both sides of the blanket in such a way as to permit two separate printing jobs.
