    摘要: A method of communicating speech comprising time-warping a residual low band speech signal to an expanded or compressed version of the residual low band speech signal, time-warping a high band speech signal to an expanded or compressed version of the high band speech signal, and merging the time-warped low band and high band speech signals to give an entire time-warped speech signal. In the low band, the residual low band speech signal is synthesized after time-warping of the residual low band signal while in the high band, an unwarped high band signal is synthesized before time-warping of the high band speech signal. The method may further comprise classifying speech segments and encoding the speech segments. The encoding of the speech segments may be one of code-excited linear prediction, noise-excited linear prediction or ⅛ frame (silence) coding.

    摘要: Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switched communications. The de-jitter buffer methods and apparatus presented modify the playback of packets dependent upon whether silence periods are detected inter-sentence or intra-sentence to optimize voice quality in a communication system. In one example, a de-jitter buffer determines the length of at least one silence period associated with a plurality of received packets and determines a time to transmit a portion of the packets based on the determined length of the silence period. In another example, a silence characterizer unit performs this function.
