    • Providing VOIP barge-in support for a half-duplex DSR client on a full-duplex network by buffering, in a half-duplex DSR client, input audio from the full-duplex network; 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 VOIP audio data bearing time stamps later than the time stamp of the recognition notification.
    • 通过在半双工DSR客户端中通过缓冲从全双工网络输入音频,在全双工网络上提供VOIP支持半双工DSR客户端的支持; 通过半双工DSR客户端播放缓冲输入音频; 在半双工DSR客户端的语音活动期间暂停播放缓冲输入音频; 在半双工DSR客户端的语音活动期间,通过全双工网络将话音发送到语音服务器; 通过语音服务器通过全双工网络在半双工DSR客户端中接收语音识别通知,具有时间戳; 并且响应于接收到通知,恢复播放缓冲的输入音频,包括播放比识别通知的时间戳更晚的缓存的支持时间戳的VOIP音频数据。
