Rather sending the speech signal the extracted features are sent to the receiver for authentication. It is a blind watermarking technique in which the host signal is not required for watermark extraction. Authentication is done by detecting the errors in the signal based on their extracted features.

In [ 1 ], based on codebook-excited linear prediction, an authentication scheme is proposed for compressed speech signal. Watermark bits are generated by codebook-excite linear prediction and embedded by quantifying least significant bits (LSBs). It’s known that, LSBs is fragile to signal processing operations.

Review of speech authentication algorithms based on watermarking. The speech watermarking schemes reviewed above mainly aim at copyright protection. So they are robust in nature. In authentication applications, a fragile watermark is preferred. Wu and Kuo presented a fragile watermarking scheme by quantization of DFT coefficients in log scale . The distortion is …
