Perceptual SpeechQuality Assessment from Narrowband Telephony to Wideband Audio

Document Thumbnail

Assessment of perceived audio quality has become separately established for telephone-bandwidth and high-quality audio. Seeking a model for use across both applications, we examine requirements for end-to-end speech quality assessment of channels at a range of audio bandwidths, in the presence of coding and noise. Results from a new wideband version of the perceptual analysis/measurement system (PAMS) are presented.
