Is STIPa a Robust Measure of Speech Intelligibility Performance?

Document Thumbnail

STIPa (STI for PA systems) is rapidly becoming a popular method of assessing speech intelligibility. It was conceived in order to overcome the problems associated with RaSTI when measuring the potential intelligibility performance of a sound system. The paper reports the results of extensive testing carried out on a variety of sound systems and controlled test environments using measurement equipment from four different manufacturers. It is concluded, that whilst theoretically, STIPa should be able to accurately predict STI, in practice, actually realising this goal may not be quite so straightforward. A number of error mechanisms were found and are reported together with estimations of the typical measurement accuracy and repeatability that can be expected when undertaking STI performance testing.
