Conventional linear-prediction-based speech coding algorithm suffer form the requirement of encoding the prediction error signal, which makes it difficult to achieve the goal of having the overall bit rate to be less than 1kbps.
In this thesis, we propose a new method to compress the linear prediction error signal. The main idea of the proposed method is to combine the prosody modification technique commonly used in speech synthesis systems. By re-producing the prediction error signal using the TD-PSOLA algorithm for speech prosody modification, the storage requirement of the prediction error signal.
