Embodiment Construction
[0061] The present invention will be described in detail below with specific embodiments in conjunction with the accompanying drawings.
[0062] The present invention is a volume control method and system. On the basis of the volume automatic gain control commonly used at present, the volume state of the voice stream is defined in advance, the volume state of the current voice stream is judged, and the volume of the voice stream is adjusted accordingly according to the judgment result. Adjust, and finally output the volume-adjusted voice stream.
[0063] figure 1 Shown is a schematic flow chart of the application of the present invention.
[0064] Step 101, define the voice stream volume state.
[0065] This solution pre-defines the voice stream as several volume states. In one embodiment of this program, the voice stream is pre-defined as three volume states, such as figure 1 As shown, they are the normal volume state, the mute state and the high volume state, and set the ...
