SCD: Secret communication devices (SCD to control user's audio noise in confidential manner)

Communication system plays a vital role for interacting with other people and transfers their messages in symbolic form, audio or both. People generally use mobile phones to interact with each other. Sometimes there arises a requirement for people to share their confidential data via communicating devices with other people. During such communication people ignore the speech level or pitch used to communicate. This may leek their confidential data and it may be misused by the surrounding environment in many ways. Due to this ignorance people may face many problems and sometimes this may even lead to substantial losses. But sometimes the exchange of confidential data becomes so crucial that it has to be transferred via available communication medium. But at the same time the secrecy of data needs to be suitably ensured. This requires the mechanism to ensure confidentiality of spoken words so that it may not get leaked to the environment. Therefore in order to control this, the author proposes a small device to be embedded to the communication device (mobile phones etc.). It should have the ability to recognize the lowest pitch level which is sufficient to perceive the desired input and interpret the said conversation accurately.
