The invention provides a novel improved voice communication system, which comprises a high-sound-quality denoising method and a high-sound-quality denoising device, and can overcome the limitation and difficulty of the traditional technology. The invention discloses a noise elimination device which comprises a vibration sensor and a microphone and is used for acquiring and transmitting a voice signal as input voice. The vibration sensor is used for acquiring a vibration signal corresponding to a voice signal, the vibration signal is used as a reference signal to eliminate noise from a noisy environment, the vibration signal and speaker information are combined and converted into an intermediate language representation PDL, and the PDL is mapped to full-band high-tone-quality clean acoustic representation. And finally, synthesizing a clear full-band voice of the speaker, wherein the voice has no difference with a noiseless voice obtained from the microphone. 本发明提供了一个新型改进的语音通信系统，它包括高音质去噪方法和装置，能够克服传统技术的限制和困难。本发明
