Design and Implementation of Voice Recording System Prototype

Embedded System for recording audio signal finds enormous applications in industry as well as home appliances. Such applications cover secured access to the use of electrical appliances through voice signals to a greater extent. For Such appliances requiring secured access, the speech signal is the simple and easiest option to utilize. Audio recording and storing is a primary requirement for such biometric parameter access. While Digital Signal Processors are costly, design and Implementation of a Voice recording system using 16 bit MSP430 series microcontroller from Texas Instruments is presented here. The complete system with prototype along with the usage of personal computer for this task is presented here.
