Speech analysis and synthesis by linear prediction of the speech wave

BS Atal, SL Hanauer - The journal of the acoustical society of America, 1971 - pubs.aip.org
We describe a procedure for efficient encoding of the speech wave by representing it in
terms of time‐varying parameters related to the transfer function of the vocal tract and the
characteristics of the excitation. The speech wave, sampled at 10 kHz, is analyzed by
predicting the present speech sample as a linear combination of the 12 previous samples.
The 12 predictor coefficients are determined by minimizing the mean‐squared error
between the actual and the predicted values of the speech samples. Fifteen parameters …
