Abstract
This chapter deals with speech processing standards for 64,32, 16 kb/s and lower rate coders and more generally, speech-band signals which are or will be promulgated by CCITT and NATO. The International Telegraph and Telephone Consultative Committee (CCITT) deals, among other things, with speech processing within the context of ISDN. Within NATO there are also bodies promulgating standards which make interoperability possible without complex and expensive interfaces.
The chapter highlights also some of the applications for low-bit rate coding and the related work undertaken by CCITT Study Groups which are responsible for developing standards in terms of encoding algorithms, codec design objectives as well as standards on the assessment of speech transmission quality.
