Embodiment Construction

[0056] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] see figure 1 , is a schematic flowchart of a speech signal processing method of the present invention, the method includes:

[0058] Step 101: Receive and store the voice data frame sent by the user terminal.

[0059]Specifically, the user terminal samples and encodes an analog voice signal generated during a call to form a PCM (Pulse Code Modulation, pulse code modulation, detection PCM) signal, and uses a time division multi...

Abstract

The embodiment of the invention discloses a voice signal processing method which comprises the following steps: receiving and storing voice data frames sent by a user terminal, wherein each voice data frame comprises N time slot channels; inserting test data into the designated time slot channels of the voice data frames, wherein the test data is used for detecting whether noise exists in the voice data frames; and sending the voice data frames comprising the test data. After the voice signal processing method is adopted, the test data is inserted into the time slot channels of the voice data frames, so that channels at detection ends check whether the test data is correct to estimate voice quality, therefore, detection automation is realized, detection efficiency is improved, the deviation problem caused by manual judgment is also avoided and accuracy of a detection result is improved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a voice signal processing and detection method and related equipment. Background technique [0002] Time Division Multiplexing (TDM) is a multiplexing technique by which two or more signals or data streams can be simultaneously transmitted on a communication line, which appears as sub-channels of the same communication channel. But from a physical point of view, signals still occupy physical channels in turn. The time domain is divided into periodic segments, each segment has a fixed length, and each segment is used to transmit a sub-channel. [0003] In the current telecom TDM system, the transmission rate of each voice channel is 64kbps, that is, the voice data is received every 125us. For occasional small amount of data distortion, the human ear cannot distinguish it, but when the noise accumulates in a short time When it reaches a certain number, it will be perceived b...
