Title: METHOD AND DEVICE FOR OBJECTIVE VOICE QUALITY ASSESSMENT PROCESSING OF INTERNET PHONE CALLS
Abstract:
Disclosed is a method for objective voice quality assessment processing of internet phone calls, comprising: obtaining multiple groups of RTP packet streams and decoding each group of RTP packet streams to obtain degraded voice and payload information; obtaining necessary voice parameters for the degraded voice of each group; calculating an assessment median of each group of RTP packet streams according to the payload information and pseudo-reference voice of each group of RTP packet streams; obtaining subjective voice quality assessment values of the multiple groups of RTP packet streams; and constructing a calculation function for objective voice quality assessment of RTP packet streams according to the necessary voice parameters, assessment median, and subjective voice quality assessment value corresponding to each group of RTP packet streams. Also disclosed is a device for objective voice quality assessment processing of internet phone calls. The method and device of the present invention are applicable to online internet voice quality assessment scenarios, have a smaller data calculation quantity as compared with the existing voice quality assessment approaches, achieve real-time assessment, and have high voice quality assessment accuracy.
