EasyVR 3 Plus

EasyVR 3 Plus 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 Plus module can be used with any host with a 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.

EasyVR 3 Plus allows up to 256 user-defined Speaker Dependent (SD) or Speaker Verification (SV) commands, that can be trained in ANY language, divided into maximum 16 groups (up to 32 SD or 5 SV commands each).

NOTE: The headers are not assembled and need to be soldered if needed. The microphone and the speaker wire with connector are delivered along with the board, the speaker is not included.
