EasyVR 3 Speech Recognition

Availability: In stock

Exc. VAT: £24.00 Inc. VAT: £28.80



Quick overview

The EasyVR 3 has more memory for custom vocabularies and compressed sounds, a breadboard friendly form factor and a quick connection option for the PC.

The EasyVR Shield 3  has improved compatibility with Arduino boards, either with 5V or 3.3V voltage levels.


The EasyVR 3 is a multi-purpose speech recognition module designed to easily add versatile, robust and cost effective speech recognition capabilities to almost any application.

The EasyVR 3 module can be used with any host with an UART interface powered at 3.3V – 5V, such as PIC and Arduino boards. Some application examples include home automation, such as voice controlled light switches, locks, curtains or kitchen appliances, or adding “hearing” to the most popular robots on the market.

It can be easily plugged into a solder-less breadboard or standard prototyping board, and it is compatible with the mikroBUS™ specifications (see

Separate male headers are provided inside the package, along with a microphone cable assembly and speaker wires (loudspeaker not included).
