We present in this paper an 8 kbit/s speech coder with a 6 ms frame-length. The coder utilizes backward adaptation for updating the LP parameters, and improved forward pitch analysis. A new frequency domain approach called Transform Coded Excitation (TCX) 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. |
