Summary:
|
This Supplement will provide examples of experiments for which ITU-T Rec. P.800 has been used successfully. The information contained in this Supplement will provide additional guidance to ITU-T Rec. P.800 users on how these experiments were conducted so that it would be of help when planning future P.800 quality assessments, for instance for the use of ITU-T Rec. P.800 DCR testing in the standardization of 3GPP IVAS, a spatial voice and audio codec. The Supplement will thus collect such use case examples and derive best practices and potentially don’t dos, as a guidance for the user. In addition, usage of reference units in P.800 tests will be described when applied to stereo/spatial audio. It should be noted that the use of P.800 is not limited to the examples of instructions and reference degradation conditions presented in this document.
Here are a few use case examples that are planned to be included:
For example, a large number of P.800 ACR tests were conducted for ITU-T Rec. P.863 standardization. The so-called full-scale SWB experiments had specific test designs, which included mixed-bandwidth samples and a set of anchor conditions for test-to-test consistency. Examples for further P.800 use cases are speech quality evaluations at SWB and FB audio bandwidths and even mixed content quality evaluations during the standardization of the 3GPP EVS codec. P.800 methods were also successfully used for the stereo speech quality evaluation as part of the ITU-T Rec. P.811 standardization. Recently, P.800 experiments were carried out for spatial speech quality evaluations. Furthermore, P.800 experiments with extended scales, e.g., nine-grade scale for ACR, have been used in various SWB/FB and spatial speech quality evaluations.
