Abstract
Techniques described herein may use perceptual quality measurement techniques to test and/or evaluate communication sessions between mobile devices. A method may include receiving, by a mobile device and as part of an audio or video call with a second mobile device, a streamed version of a reference audio or video file; and reading a version of the reference audio or video file that was previously stored locally to the mobile device. The method may further include calculating, based on a comparison of the streamed version of the reference audio or video file to the version of the reference audio video file that was stored locally, a perceptual quality score for the streamed version of the reference audio or video file.
