Voice quality evaluation method and device

Abstract

According to the embodiment, the invention discloses a voice quality evaluation method and an evaluation device. The method comprises the following steps: acquiring voice pockets received by a plurality of nodes in a network transmission path; acquiring index data of the various voice pockets in accordance with preset frequency; in accordance with the acquired index data, implementing factor analysis on indexes involved in the index data, so as to obtain a plurality of public factors which are mutually not related, weights of the various public factors as well as score weights of the various public factors on the various indexes; in accordance with the index data of the voice pockets, weights of the various public factors and the score weights of the various public factors on the various indexes, calculating voice quality scores of the voice pockets; and in accordance with the voice quality scores of the various voice pockets, confirming an inferior quality path in the network transmission path. According to the scheme provided by the invention, the inferior quality path in the network transmission path can be confirmed, so that subsequent optimization for the inferior quality pathcan be implemented conveniently; and therefore, network voice quality can be improved, and optimization efficiency can be increased.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a voice quality assessment method and device. Background technique [0002] With the continuous maturity of communication technology, voice services have been more and more widely used. In order to better transmit voice signals and satisfy end users with a good experience of voice services, it is necessary to evaluate the voice service quality of the communication network. test. [0003] Existing voice service quality assessment methods are usually based on a mean opinion score (Mean Opinion Score, MOS for short) mechanism, and common methods include a subjective MOS value assessment method and an objective MOS value assessment method. In the MOS mechanism, the MOS value is an important index to measure the voice quality of the communication system, and according to the different distortion conditions of the voice quality, the MOS value is divi...

Problems solved by technology

[0005] However, although the MOS value obtained according to the objective MOS value evaluation method can determine the phenomenon of voice quality degradation in the network transmission path, it cannot directly determine the path of voice quality degradation in the network transmission path

In this way, when there is an optimization requirement to improve the voice quality of the network in the future, it is first necessary to detect the network transmission path where the voice quality degrades, and then optimize after finding the path where the voice quality degrades, which is inefficient.
