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.
Claims17
A computer-implemented method, comprising:
- obtaining, by a user terminal, an audio signal;
- determining a ratio of a sampling rate of a predetermined voice signal to a frequency of the predetermined voice signal;
- dividing, by the user terminal, the audio signal into a maximum quantity of short-time energy frames containing a plurality of samples based on the ratio;
- determining, by the user terminal, energy of each short-time energy frame;
- and
- determining, by the user terminal, whether the audio signal includes a voice signal based on the energy of each short-time energy frame.
