Speech coding principles of speech coding, narrowband speech codecs. Such codecs are used to give an efficient digital representation of telephone bandwidth speech. Often the speech is bandlimited to between 200 and 3400 Hz, and is sampled at 8 kHz

Speech coding demonstrations demonstrates the speech/music quality obtained after one stage of encoding and decoding through the specified speech codec

Speech compression how to reduce bandwith, the aim of speech compression is to produce a compact representation of speech sounds such that when reconstructed it is perceived to be close to the original
