Abstract

The present application provides a voice quality detection system, method, and PESQ control terminal, wherein the voice quality detection system includes a voice quality sensory evaluation PESQ control terminal, a sound card, a first connection line, a second connection line, a first terminal and a second connection line. terminal, the PESQ control terminal is connected to the sound card, the sound card is connected to the first terminal through the first connection line, the sound card is connected to the first terminal through the second connection line, and the ordinary sound card is used as the audio sending and receiving device in the PESQ system to realize the reduction of voice The purpose of quality inspection cost.

Description

technical field [0001] The embodiment of the present application relates to a voice quality detection technology, in particular to a voice quality detection system, method and PESQ control terminal. Background technique [0002] At present, the industry evaluates the speech quality of the terminal under test through the Perceptual Evaluation of Speech Quality (PESQ) specified in the P.862 standard of the International Telecommunications Union (ITU). [0003] The PESQ test system compares the sound source signal with the degraded signal, and obtains a Mean Opinion Score (MOS) value similar to the artificial hearing test based on the comparison result, which is called the PESQ score, so as to realize the decoder, end-to-end Voice quality detection. The PESQ test system includes a PESQ control terminal, an audio sending and receiving device and a connection line, wherein the PESQ control terminal is connected to the audio sending and receiving device, and the audio sending and...
