scope:

This Supplement provides examples of experiments related to relevant standardization efforts in the ITU-T and 3rd Generation Partnership Project (3GPP) for which [ITU-T P.800] has been used, including quality assessments in the context of the standardization of enhanced voice services and immersive voice and audio services. The information provided by this Supplement on how these experiments were conducted is intended as guidance for ITU-T P.800 users when planning ITU-T P.800 quality assessments.

This Supplement also contains a collection of best practices for test design, preparation and execution.

In addition, specific reference conditions and tools used in the ITU-T P.800 use case examples are described in detail.

It should be noted that the use of [ITU-T P.800] is not limited to the examples, guidelines or reference conditions and tools described in this Supplement. Also note that there is no universal test method that can be applied under all circumstances. When designing an experiment, careful consideration is advised on the choice of a proper test method.
