Why an Arduino hacker should use a voice recognition shield for voice commands when a smartphone can do that? There are plenty of shields you can buy at the store to build a voice recognition application with Arduino board. However, instead concentrating on additional parts that can be attached, the instructable user ram mere shows how to use an Arduino smartphone to send voice commands to Arduino board.

What You’ll Need

You need a plan to start making the voice recognition system. The plan has to include an Arduino board, some wires, LED’s, and the most important is the BlueAct app that run on the Android smartphone. The BlueAct app is featured with more actions than ‘Voice’. There are actions such as ‘Vibration’, ‘SMS’, ‘Acceleromter’, and more. All these actions allow the users to control the Arduino board using different features of a smartphone.

How it Works

The user can send commands in two ways: using a Serial Cable or through Bluetooth connectivity. The application support both methods of sending voice commands, but instead paying money on a serial cable, using the Bluetooth connectivity has zero costs.

Now you can apply all your electronics and programming skills and check the full version of the tutorial to build the voice recognition system using the Arduino board and BlueAct app.
