Abstract
The coder utilizes backward adaptation for updating the LP (linear prediction) parameters, and improved forward pitch analysis. A novel frequency domain approach called transform coded excitation is used for efficient quantization and encoding of the innovative excitation signal. The coder uses a combination of time-domain (linear prediction and pitch analysis) and frequency-domain (transform coding) techniques to achieve the best reproduction of the original signal in the perceptual sense. Good speech quality was obtained with this approach.Keywords
