Are you a Student, Engineer, or Someone that loves trying New things in a new way, here is a Mobile Application for you. The Speech Control Application uses your speech to control electronic devices Wirelessly Via Bluetooth Technology. It operates using an Electronic Circuit built around Arduino Uno, Bluetooth Module and a LED. When you speak to the mobile phone through its microphone, your speech translates to text using the default Google Speech to Text Setting on your mobile phone. The text displayed is then sent over to the electronic device serially using the Bluetooth communication path. The device then reads the speech commands and then controls the LED automatically according to the programmed text control. The LED can be replaced with Relay Switch for AC Switching.
