Claim 13:
14. The method according to claim 13, wherein the calculating the corresponding instant voice adjustment parameter comprises:
determining a maximum signal-to-noise ratio and a minimum signal-to-noise ratio from the single-frame signal-to-noise ratios of the audio frames in the respective call audio stream;
determining a first difference according to a difference between the maximum signal-to-noise ratio and the minimum signal-to-noise ratio;
determining a second difference for the current frame currently processed in the audio frames of the respective call audio stream according to a difference between the single-frame signal-to-noise ratio of the current frame and the minimum signal-to-noise ratio; and
determining the instant voice adjustment parameter corresponding to the current frame according to a preset minimum gain value, the first difference, and the second difference.
