Adding speech control to Arduino

Although there has been several attempts at onboard speech recognition on the Arduino platform, the most successful systems need an external speech processor due to the computing effort required. One example of this has been demonstrated by Chanud Yasanayake who uses a PC running Bitvoicer speech recognition software, which can take care of the voice recognition then send commands via USB to an Arduino or compatible board.

This can then be used to control external circuitry for the final purpose - in this case a handheld gaming console. The circuitry uses relays to electrically isolate the Arduino from the console's control buttons, however for lower-current circuitry perhaps optocouplers could be used instead. Nevertheless the following video offers a demonstration of the system at work:

For complete details including circuitry and code, check out the project Instructable page. And for more, we're on facebooktwitter and Google+, so follow us for news and product updates as well.

If you're looking for a simple way to control many relays from your Arduino, without using up all your digital I/O pins - check out our Relay8:  driver shield:

So what is the RELAY8:? It's a new Arduino shield that allows you to drive up to 8 relays from your Arduino using just 2 I/O pins with this shield. It communicates with your board using I2C, so you can even stack several shields together to drive 16, 24, or more outputs! Includes back-EMF protection and works with a wide range of relays. Perfect for home automation projects! For more information and to order, click here.
