摘要
The evolution towards interactive multimedia applications and the implementation of new signal
processing devices both in terminals and communication networks means that a number of
sophisticated signal processing algorithms will be deployed for echo control, noise reduction, level
control, voice activity detection, speech coding, speech recognition and voice-band traffic
technologies. These may interact with one another and with the imperfections of transmission
system, such delay and error bursts, to adversely affect the quality of speech and voice-band signals.
The purpose of this Recommendation is to describe interaction aspects and to provide requirements
for the interoperability of Speech Processing Network Equipment (SPNE), between different SPNE,
between SPNE and terminals and between SPNE and the transmission systems in the General
Switched Telephone Network including mobile networks.
