Speech quality of VoIP (voice over Internet protocol) may potentially be degraded by transmission errors such as packet loss and delay, which is basically inevitable in best-effort communications. This study investigates an error concealment technique for such degradation by using a receiver-based technique called pitch waveform replication. For enhancing the conventional technique, this study proposes a waveform reconstruction technique that also takes account of the pitch variation between… CONTINUE READING
