SPEECH CODING CHARACTERISTICS • Speech coders are lossy coders, i.e. the decoded signal is different from the original • The goal in speech coding is to minimize the distortion at a given bit rate, or minimize the bit rate to reach a given distortion • Metrics in speech coding: • Objective measure of distortion is SNR (Signal to noise ratio); SNR does not correlate …

• Speech coding is necessary for cellular phones, which has limited data rate for each user (<=16 kbps is desired!). • For the same mobile user, the lower the bit rate for a voice call, the more other services (data/image/video) can be accommodated. • Speech coding is also necessary for voice-over-IP, audio-visual

SPEECH CODING Speech coding is a talent of compressing and then converting speech signals for effective transmission or stowage. Speech coding system initially having the input speech signal which is in the form of analog in nature is need to digitized using a sampler, analog to digital converter and a filter. Speech coding techniques are mainly two types which are
