A near-end audio signal is received by at least one microphone of the communication apparatus. Voice and noise energy data are generated by performing voice activity detection on the near-end audio signal. A noise amount is obtained by performing noise energy calculation with the noise energy data. Whether the noise amount exceeds a first noise amount threshold is determined. If the noise amount exceeds the first noise amount threshold, a sidetone mode of the communication apparatus is enabled to produce a sidetone signal according to the voice energy data and play the sidetone signal through a speaker thereof. A noise suppression mode is enabled to produce a far-end audio signal according to the voice energy data and transmitting the far-end audio signal by a communication module of the communication apparatus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication apparatus and voice processing method therefor","description":"A voice processing method for use in a communication apparatus, in an embodiment, includes the following steps.
