| Research Abstract |
An information hiding technique called steganography can be employed for secretly transmitting side information without increasing its data size. This idea can be applied to enhancing the quality of speech communications using sub-channel data transmission based on information hiding techniques. The experimental results of this study indicate that the proposed techniques outperform the conventional ones.
