Voice Recognition Module Kit V3.1 compatible with Arduino is a compact and easy-control speaking recognition board. RoboticsBD
Voice Recognition Module Kit V3.1 product is a speaker-dependent voice recognition module. It supports up to 80 voice commands in all. Max 7 voice commands could work at the same time. Any sound could be trained as the command. Users need to train the module first before let it recognizing any voice command.
This board has 2 controlling ways: Serial Port (full function), General Input Pins (part of a function). General Output Pins on the board could generate several kinds of waves while the corresponding voice command was recognized. Featured By RoboticsBD.

We have Voice Recognition module V2 and it supports 15 commands in all and only 5 commands at the same time. On V2, voice commands are separated into 3 groups while you training it. And only one group (5 commands) could be imported into Recognizer. It means only 5 voice commands are effective at the same time.
On V3.1, voice commands are stored in one large group like a library. Any 7 voice commands in the library could be imported into recognizer. It means 7 commands are effective at the same time. RoboticsBD
