Low Delay Coding of Speech and Audio Using Nonuniform Band Filter Banksand audio coding. For speech and audio signals, the analysis-synthesis filter bank can be thought of as modeling the human auditory system, where the critical band model of aural perception is reflected in the design of the filter banks. The constraints imposed by the aural model are best met by non

Speech Quality Evaluation of the European, North-American and Japanese Speech Coding Standards for Dre at least three TDMA digital cellular standard systems: the European (GSM) [1], the North-American (TIA) [2] and the Japanese [3]. A fundamental part of these systems to achieve good speech quality is the speech coding procedure. The three speech coding schemes, RPE-LTP at 13 kbit/s, VSELP at 8 kb

QCELP: A Variable Rate Speech Coder for CDMA Digital Cellularystems. The use of a variable rate speech coder can reduce the average data rate required to transmit conversational speech by a factor of two or more, while providing many other advantages. This reduction in average data rate leads to a factor of two increase in the capacity of a Code Division Mult
