Patent ID: 7848314

Claim:
A method of providing voice over the Internet Protocol (‘VOIP’) barge-in support for a half-duplex distributed speech recognition (‘DSR’) client on a full-duplex network, the method comprising: buffering, in the half-duplex DSR client, input audio from the full-duplex network, the input audio comprising VOIP audio data for output through the half-duplex DSR client, the buffered input audio bearing time stamps; playing, through the half-duplex DSR client, the buffered input audio; pausing, during voice activity on the half-duplex DSR client, the playing of the buffered input audio; sending, during voice activity on the half-duplex DSR client, speech for recognition through the full-duplex network to a voice server; receiving in the half-duplex DSR client through the full-duplex network from the voice server notification of speech recognition, the notification bearing a time stamp; and responsive to receiving the notification, resuming the playing of the buffered input audio, including playing only buffered input audio bearing time stamps later than the time stamp of the recognition notification.
