scope:
This part of IEC 60268 defines objective methods for rating the transmission quality of speech with respect to intelligibility. The four methods, which are closely related, are referred to as the "STI," the "STITEL", the "STIPA" and the "RASTI" methods (see Clause 3). The methods are intended for rating speech transmission with or without sound systems.
A survey of other methods of determining or predicting speech intelligibility is also included, together with a method of correlating the results of different methods of determination.
