Abstract:
A method for encoding speech information comprising:generating at a local user location, as an intermediate step in speech recognition, a context dependent phoneme network from speech in a phoneme network generator using an acoustic model that adapts to a user's voice, wherein the context dependent phoneme network is a representation of speech input in the form of nodes and arcs, each arc representing a score of a phoneme with start and end times represented by nodes, the phoneme network enabling the speech input to be represented by the nodes and arcs thereby resulting in the speech input being packaged into an intermediate format that is independent of vocabulary, language model, user and physical environment; andtransmitting the context dependent phoneme network to one or more application programs located remotely from the local user, to enable the remote application programs to effect recognition of speech in each application program using a vocabulary and language model selected by the application program, thereby obviating the need for the local user location to perform recognition of speech tasks.
