4.0 Speech Compression Waveform Coding and Vocoding
An effective strategy commonly used in voice-compression is to mathematically model the voice and transmit the parameters associated with the model.
This process is referred to as the "Process of Analysis and Synthesis" (also called Vocoding). Most Vocoding techniques are based on Linear Predictive Coding.
