Antscran over at the 430h forum posted a how-to on using an Android phone and voice commands to control a MSP430G2553:
In this tutorial I will demonstrate a MSP430 voice control over Bluetooth, using a HC06 Bluetooth module. I will be using an Android App I programmed which can be downloaded and installed, the C code for the MSP430 is also downloadable at the end of the tutorial. So before we look at everything in further detail, the video below gives a demonstration of what the simple App and basic hardware set/up can do. Note it was filmed with an older phone, so excuse the quality and dodgy camera angles.
Check out the video after the break.
