![]() ![]() It aims to emblem the amplitude and frequency characteristic of speech signal onto the synthesis signal, while maintaining the pitch of the speech signal. The vocoder takes two signals and creates a third signal using the spectral information of the two input signals. ![]() Then other audio signals are affected by the use of that characteristic signal. Vocoder works in such a way that it first captures the characteristic element of the signal. This reconstructed waveform at the receiver must be similar and not identical to the waveform actually transmitted. We can simply transmit the information by which one can reconstruct that particular waveform. Whenever a speech signal is transmitted, it is not needed to transmit the precise waveform. ![]()
