Transferring voice command platform (VCP) functions and/or grammar together with a call from one VCP to another

摘要

A method of processing a call in a voice-command platform includes a step of transferring the call from the voice-command platform to a second voice-command platform. The method continues with the step of transmitting, either directly or indirectly, grammar information from the voice command platform to the second voice-command platform for use by a voice command application executing in the second voice-command platform in processing the call. The grammar information could be logic defining application-level grammar or system-level grammar. Alternatively, the grammar information could be a network address (e.g., URI or URL) where the grammar is stored in a file, e.g., a VXML document. The features of this invention enhance the user experience by preserving and using grammars used initially in the first voice command platform in other, downstream, voice command platforms.
