Do you make time to talk to your Arduino? Maybe you should! The EasyVR Shield 2.0 is a voice recognition shield for Arduino boards integrating an EasyVR module. It includes all of the features of the EasyVR module in a shield form factor that simplifies connection to the Arduino main board and PC.
EasyVR 2.0 is a multi-purpose speech recognition module designed to add versatile, robust and cost effective speech and voice recognition capabilities to virtually any application. EasyVR is the third generation version of the successful VRbot module and builds on the features and functionality of its predecessor. In addition to the EasyVR 2.0 features like 28 user-defined Speaker Dependent (SD) triggers and 28 custom speaker independent (SI) commands, the shield has additional connectors for the microphone input, an 8 ohm speaker output, audio line-out/headphone jack, and access to the I/O pins of the EasyVR module. A programmable LED is also included to show feedback during recognition tasks.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

The board works. It's kinda cool to be able to talk to your project and have it answer. BUT...The documentation on how to program it is horrible.It's not an easy thing to get working. Major hint that's not in the manual: the button that will compose a sketch for you automatically. It helps a lot! Also research the jumper settings....
I got this module because I need it to recognize a sound (shutter sound of a camera) and it works beautifully. It took me a while figuring out the sequence for the training. The documentation, although a complete API reference, could be helped with more of a usage narrative.
But from a recognition perspective, I could not have found a better module. Kudos to the developers.
The other reviewer mentioned the jumper settings. Yes, that is a key to making it working. There is a lot of base understanding of the module expected before you use it.
There were a few compiling issues with the new EasyVR Arduino library. Ultimately I figured out I had to download and old revision of their library and move a Header and C file into the new library.
I did that and everything worked great and I'm now voice controlling Lighting and Fans in my home.
