History

Provides an overview of the non-intrusive methods available for measuring speech transmission quality. It applies only for narrowband (i.e. between 300 Hz and 3 400 Hz) communications, assumed between handset terminals. Its aim is to give information and guidance primarily for operators, users, consumer organizations and regulators who wish to measure or compare the speech transmission quality provided by different networks.
