“The best form of compression for voice data makes use of the structure of speech - the Linear Predictive Filter. The basic idea is that the data is compressed by using an input code word that represents the sound made in the throat by the vocal chords. Then a set of parameters are set in a filter which represents the shape of the mouth and resonant cavities. The parameters are set so that the output matches the sound as well as it can - this is an example of analysis by synthesis, i.e. you analyze a signal by setting up a system that creates it accurately.”
