the emerging scenario of real-time voice transmission over wireless medium is being exploited by various new set of applications to abate the growing need of a secured, low-cost and compact embedded device. In this project a new fully-functional embedded device has been proposed which is able to stream or transmit voice in real-time over WI-FI (IEEE 802.11) with an acceptable audio quality. The proposed system has features such as feeding recorded audio directly into a remote computer for storage from a voice recorder module. Given the credit-card- sized single-board and low price, Raspberry Pi model B is the most appropriate as a portable device for our wireless requirements. In this project, the Raspberry Pi is intended to have capability of gathering audio from an USB microphone connected to it and transmit it to another remote computer in real time. The Raspberry Pi is connected to the workstation. So, there is no need of a separate monitor. To do this, SSH(Secure SHell) is used, which is a cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked nodes. Open source Linux based OS is used in this project to keep the cost low.
