Abstract

Wireless systems involved in transmission of speech envisage that efficient and effective methods be developed to transmit and receive the same while maintaining quality-of-speech, especially at the receiving end. The goal of the project is to implement variable bitrate steganographic data transmission over GSM Adaptive Multi Rate (AMR) coder. In order to facilitate the same bitrate steganographic data transmission a few pulses are identified and utilized for embedding and hiding the data bits into them. Joint speech coding and data hiding is accomplished. This is implemented on the standard AMR coder and the performance evaluation using subjective measures that include mean opinion score and the objective measures like Perceptual Evaluation of Speech Quality, Segmental SNR are done. The stego signal, which is small data information, is used for embedding over the encoded wave file.
