Abstract
Audio communication has become very much widely prevalent in this modern era. With the increase of its availability and usability, the privacy concern has become an important issue to be addressed. The participants of an audio conversation like to secure their privacy without any hindrance in the regular activities. Especially, such type of technology is expected in real time. In the past, some notable solution has been provided to resolve privacy-related issues, however, that solution was not that much user-friendly. In this paper, an approach has been proposed to provide the participants of an audio communication full audio privacy in real time. It will completely hide the vocal identity without compromising any information of the audio stream. This approach does not involve any extra hardware mechanism or data analysis to provide the service. In either way, it is very much user-friendly and inexpensive solution for the users to preserve their security in audio conversation.
