Embodiment Construction

[0021] The method for selecting and matching the voice enhancement channel of the communication network according to the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The voice enhancement channel of the voice enhancement function module has input voice code stream and output voice code stream, and includes some or all of the following voice enhancement functions: AGC, AEC, NR, NC.

[0023] Such as figure 1 As shown, the present invention provides a method for selecting and matching voice enhancement channels in a communication network, which includes the following steps:

[0024] Step 1. Firstly, determine how much computing power the above-mentioned voice enhancement system occupies by the calculation processing capability P of the entire voice enhancement system and the AGC, AEC, NR, and NC functions of a single voice enhancement channel.

[0025] The calculation processing capacity of the ...

Abstract

The invention provides a matching method of the speech enhancement channel of the communication network. The method comprises the following procedure, firstly determines the operation processing ability of entire speech enhancement system and the respective occupied speech enhancement system of each speech enhancement function of each speech enhancement channel, calculates the occupied calculationability and the remaining calculation processing ability of the speech enhancement system, judges whether the remaining calculation processing ability meets the requirement of the speech enhancementfunction to be processed by the code-flow of the current channel, if it meets, and the procedure goes on, judges whether the filtration condition of the speech enhancement function to be processed issatisfied, if it is satisfied, then carries out the corresponding processing of the speech enhancement function on the code-flow via the speech enhancement channel and sends the code-flow after processing to the next processing unit, otherwise, directly sends the code-flow to the next processing unit. The invention solves the problem of wasting the processing ability of the speech enhancement channel of the existing configuration method.

Description

Technical field [0001] The invention relates to the field of speech enhancement processing in a communication network, in particular, the invention relates to a method for selecting and matching speech enhancement channels of a communication network. Background technique [0002] The voice enhancement function is gradually being applied to a variety of devices such as core networks and communication terminals, and has attracted more and more attention. In the communication network, the general configuration method is full configuration, that is, the voice code stream from each channel is voice enhanced through the voice enhancement channel, so as to achieve automatic gain control (Automatic Gain Control, hereinafter referred to as AGC) for each voice channel , Acoustic echo cancellation (hereinafter referred to as AEC), noise reduction (hereinafter referred to as NR), noise compensation (hereinafter referred to as NC) and other functions, bring users a clearer and more comfortabl...
