Abstract:
An audio signal is obtained by a user terminal. The audio signal is divided into a plurality of short-time energy frames based on a frequency of a predetermined voice signal. Energy of each short-time energy frame is determined. Based on the energy of each short-time energy frame, whether the audio signal includes a voice signal is determined.

Claim (Index 6):
The computer-implemented method of  claim 1 , wherein determining whether the audio signal includes a voice signal comprises:\n determining a plurality of high-energy frames, wherein each high-energy frame of the plurality of high-energy frames is a short-time energy frame where energy is greater than a predetermined threshold; determining a high-energy frame ratio that is represented by a ratio of a quantity of the plurality of high-energy frames to a quantity of the short-time energy frames included in the audio signal; determining whether the high-energy frame ratio is greater than a predetermined value; if it is determined that the high-energy frame ratio is greater than the predetermined value:\n determining that the audio signal includes a voice signal; or \n if it is determined that the high-energy frame ratio is not greater than the predetermined value:\n determining that the audio signal does not include a voice signal.
