Abstract

The invention discloses a speech enhancement quality evaluation method and device, a terminal and a storage medium, and the method comprises the steps: using a clean speech signal as an original signal, superposing different types of noises before speech enhancement to generate a noise speech signal, and generating a speech enhancement signal through speech enhancement algorithm processing; and finally, importing the clean original speech signal and the speech enhancement signal into the PESQ to obtain a speech enhancement quality evaluation score. The method can randomly simulate noise speechsignals of different scenes, and realizes more flexible and convenient speech enhancement quality evaluation in large-scale scene testing.

Description

technical field [0001] The invention relates to the technical field of voice communication, in particular to a voice enhancement quality evaluation method, device, terminal and storage medium. Background technique [0002] With the development of conference communication and VoIP communication, users have higher and higher requirements for the voice signal quality of conference terminals. Therefore, it has become the existing standard to equip conference terminals with related technologies of voice enhancement. [0003] In order to test the speech quality after speech enhancement, a terminal speech quality evaluation method and a terminal are disclosed in the prior art, wherein the method includes: the terminal obtains the source standard sound source signal according to the type of speech quality to be evaluated; The voice quality type processes the source standard audio signal; the terminal imports the source standard audio signal and the processed source standard audio si...
