SPEECH ENCODING USING ADPCM

Linear-Predictive-Coder MATLAB Implementation of LPC algorithm for speech signal # Why LPC? In communication systems it is often necessary to transmit audio(speech) signal in compressed or encoded form because of bandwidth limitation of the

The speech signal for the particular isolated word can be viewed as the one generated using the sequential generating probabilistic model known as hidden Markov model (HMM). Consider there are n states in the HMM. The particular isolated speech sig
