主权项

1. A method of synchronizing speech recognition, the method comprising:
receiving, in a client terminal having access to a voice channel and a data channel distinct from the voice channel, an audio signal including speech of a user; processing the audio signal to generate a processed speech signal, the processing comprising filtering the audio signal to remove one or more non-speech portions of the audio signal; receiving notification from a voice server of readiness to conduct speech recognition; responsive to the notification of readiness to conduct speech recognition, transmitting the processed speech signal over the data channel from the client terminal to the voice server for recognition; receiving implicit notification from the voice server to cease transmitting speech, by completion of an X+V event or a VoiceXML event associated with a prompt and a transmission of user speech; and responsive to the implicit notification from the voice server to cease transmitting speech, stopping speech transmission.
