APPARATUS AND METHOD FOR HYBRID EXCITED LINEAR PREDICTION SPEECH ENCODING

APPARATUS AND METHOD FOR HYBRID EXCITED LINEAR PREDICTION SPEECH ENCODING

A method is given of encoding a speech signal using analysis-by-synthesis to perform a flexible selection of the excitation waveforms in combination with an efficient bit allocation. This approach yields improved speech quality compared to other methods at similar bit rates.
