发明名称 METHOD FOR QUANTIZING AMPLIFICATION COEFFICIENTS FOR LINEAR PROGNOSIS SPEECH ENCODER WITH CODE EXCITATION
摘要 FIELD: encoding technologies. ^ SUBSTANCE: method includes providing speech signal in frame-based form, during processing frames and prior to processing sub-frames amplification coefficient for adaptive code book for each sub-frame of current frame is determined on basis of speech signal, vector quantization of amplification coefficients of adaptive codebook is performed, during processing of sub-frames amplification coefficient of fixed codebook is determined for each sub-frame of current frame and after processing sub-frames vector quantization is performed for amplification coefficients of codebook with delayed solution. ^ EFFECT: higher speed of operation, broader functional capabilities, higher efficiency. ^ 4 cl, 14 dwg
