Quick overview

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.

    Simple and robust documented serial protocol to access and program through the host board.

    6 General purpose I/O lines that can be controlled via UART commands.

SD Commands

SD/SV commands are entirely user-defined and they are intended to work only with the voice that trained them. SD only tries to match the trained words, while SV also tries to match the characteristics of the voice and to prevent use by unknown people (voice password). Up to 64 SD commands available starting with firmware Revision 5 included in EasyVR Commander v3.13.0 .

SI commands are meant to work with any people in the same language group and do not require training. A few pre-defined commands can be directly used, while additional commands can be created with a QuickT2SI™ Lite license (sold separately).
