Define vocoders and what are the types channel vocoders?

- Vocoders stands for Voice Coders.

- Synthetic sound is reproduced with artificial quality.

- Vocoders transmit signals with low bit rate, usually in the range of 1.2 to 2.4 KB.

- Model parameters are used by the receiver along with the transmitted parameters.

- Model parameters then synthesizes the approximation to the source output.

- The channel vocoders are linear predictive coders and code excited linear prediction.
