Abstract:
A volume adjustment method and apparatus, and a terminal is presented. Perform analysis on the collected sound signal surrounding a user terminal, to obtain composition information, where the composition information includes sound types included in the sound signal and proportions of sounds of the various types, and the sound types include blank sound, human sound, and noise; determine a current scene mode of the user terminal according to the composition information; and adjust volume of the user terminal according to the determined scene mode, thereby significantly reducing occurrence of a case, caused by mistaken determining of the scenario, in which play volume adjustment does not conform to the scenario, and enhancing user experience.

Claim (Index 15):
The terminal of  claim 9 , wherein the processor is further configured to:\n divide the collected sound signal into multiple pieces of audio data; calculate a sound frequency of each piece of audio data; classifying, according to the calculated sound frequency, each piece of audio data according to blank sound, human sound, and noise; collect statistics on proportions of blank sounds, human sounds, and noise in all pieces of audio data; calculate, for audio data distinguished as a human sound, a mel-frequency cepstral coefficient of audio data of a human sound; and collect statistics on audio data of a same mel-frequency cepstral coefficient as sounds of one person in order to determine information about a quantity of people comprised in the human sound.
