| description | The invention discloses a voice communication system and method, and relates to the technical field of voice communication. The system comprises a first electronic device and a second electronic device. The first electronic equipment is used for acquiring the waveform of the voice signal; extracting a first logarithmic magnitude spectrum and a first phase spectrum from the waveform of the voice signal through short-time Fourier transform; generating a continuous code according to the first logarithmic magnitude spectrum and the first phase spectrum; discretizing the continuous code to obtain an index vector; sending the index vector to a second electronic device; the second electronic equipment is used for generating a quantization code according to the index vector; generating a second logarithmic magnitude spectrum and a second phase spectrum according to the quantization code; and recovering the second logarithmic amplitude spectrum and the second phase spectrum into the waveform of the voice signal throug |
