EasyVR 3 Module
Product Description
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 www.mikroe.com/mikrobus).
Separate male headers are provided inside the package, along with a microphone cable assembly and
speaker wires (loudspeaker not included).
