WebIn any communication transceiver, a codec (COder/DECoder) is one of the basic building blocks for efficient transmission of data. ... (HR) speech coding exercise was started, with the objective of meeting the same basic quality of the GSM full rate by using half the bit rate (the GSM full rate speech codec requires 13 kbit/s, added to 9.8 kbit ... Speech coding is an application of data compression of digital audio signals containing speech. Speech coding uses speech-specific parameter estimation using audio signal processing techniques to model the speech signal, combined with generic data compression algorithms to represent the resulting modeled parameters in a compact bitstream. Some applications of speech coding are mobile telephony and voice over IP (VoIP). The most wid…
