Embodiment
[0044] Embodiment: Utilize the voice training set to sample at 8KHz frequency, 16-bit quantization, refer to the method in the MELP vocoder to extract the residual spectrum amplitude parameter, the dimension is 10, and form the residual spectrum amplitude set.
[0045] (12) Use vector clustering technology to train and generate a residual spectrum amplitude codebook with a size of 1024 for the above residual spectrum amplitude set;
[0046] Embodiment: Using the residual spectrum amplitude set generated in step (11), the LBG algorithm is used to generate a residual spectrum amplitude codebook C with a size of 1024.
[0047] (13) Use the training speech set to extract parameters such as line spectrum frequency, bandpass voicing degree, pitch period, energy, and residual spectrum amplitude by frame;
[0048] Embodiment: Refer to the parameter extraction method in the MELP vocoder to extract parameters such as line spectrum frequency, bandpass voicing degree, pitch period, energy...
