Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0049] Since different speech codec technologies may have different codec effects on speech, there is currently no theoretically supported method for evaluating the codec effects of different speech codec technologies. The invention provides a method for judging speech coding and decoding technologies, which uses a digital method to evaluate different speech coding and decoding technologies, eliminates the influence of human subjective factors, and obtains more accurate judging resul...

Abstract

The embodiments of the invention disclose a method, apparatus and terminal for evaluating a voice coding and decoding technology. The method comprises the following steps: after a segment of original voice is coded and decoded by use of any one voice coding technology, obtaining a segment of voice after coding and encoding; calculating an envelope variance between the original voice and the voice after the coding and decoding; and according to the envelope variance, evaluating the coding and decoding effect of the voice coding and decoding technology. According to the invention, different voice coding and decoding technologies are evaluated by use of a digitalization method, influences of manual subjective factors are eliminated, and quite accurate evaluation results can be obtained.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method, device and terminal for judging speech codec technology. Background technique [0002] There are many existing speech codec technologies, but as to which speech codec technology can produce a better speech codec effect, there is no evaluation method with theoretical support at present. [0003] The traditional method of judging speech codec technology is to judge the effect of speech codec by human subjective experience. Usually, a certain number of people are gathered, and the number of males and females is divided into half. By making subjective judgments on the coding and decoding results of various speech coding and decoding technologies, and scoring them in several levels, and finally summarizing all The scoring data are synthesized to obtain the evaluation result. [0004] Obviously, people's subjective feelings are uncertain and greatly affected by external facto...
