Abstract

A voice activity detection method includes a voice pickup module, a processing module coupled to the voice pickup module and a prompt module coupled to the processing module. The processing module is used to perform a voice activity detection method, including: receiving voice information by the voice pickup module; acquiring a volume value of the voice information by the processing module; determining by the processing module whether the volume value is less than or equal to a first volume threshold; when it is determined that the volume value is less than or equal to the first volume threshold, generating by the prompt module a first prompt message for increasing the volume value; and when it is determined that the volume value is more than the first volume threshold, generating by the prompt module a second prompt message that indicates a volume value standard has been satisfied.
