Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Speech and
15、multimedia Transmission Quality (STQ). The present document is part 1 of a multi-part deliverable covering Guidelines, objectives and results of speech quality analysis in the context of interworking Plugtests for multiplay services, as identified below: Part 1: “Guidelines and objectives“; Part 2:
16、“Results“. ETSI ETSI TR 102 716-1 V1.1.1 (2009-07)51 Scope The present document provides objectives for speech quality evaluation in the specific context of interoperability event. In this context where acoustic measurements are not possible, is specified the type of measurement chain to be implemen
17、ted and the necessary calibrations. In the present document, are presented a list of metrics that can be assessed and the mode of result presentation. It is also specified comments to be drafted in test reports to clarify the context in which analyses were carried out. 2 References References are ei
18、ther specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is accepte
