LINEAR PREDICTION OF SPEECH
block diagram of speech synthesizer using linear prediction.
voiced sound, pulse generator is selected as signal source while for unvoiced
sounds noise generator is selected as signal source.
linear prediction coefficients are used as coefficients of digital filter.
Depending upon these coefficients , the signal is passed and filtered by the
low pass filter removes high frequency noise if any from the synthesized
speech. Because of linear phase characteristic FIR filters are mostly used as
