Abstract  Abstract

The invention discloses a voice frequency data processing method, a voice frequency data processing device and a voice frequency data processing system and belongs to the technical field of communication. The voice frequency data processing method comprises the following steps: obtaining noise frames of voice frequency signals, and decomposing the current noise frames into low band noise signals and high band noise signals; using first discontinuous transmission mechanism codes to transmit the low band noise signals; and using second discontinuous transmission mechanism codes to transmit the high band noise signals. Through different processing modes to the high band noise signals and the low band noise signals, the voice frequency data processing method, the device and the system can reduce computational complexity and save coding bits on the premise of not reducing subjective quality of a coder-decoder. The saved coding bits can achieve the purpose of reducing transmission bandwidth or improving overall code quality.
