Voice Recognition Module is a compact and easy-control speaking recognition board.

This 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 a command. Users need to train the module first before letting it recognize any voice command.

This board has 2 controlling ways: Serial Port (full function), General Input Pins (part of function). General Output Pins on the board could generate several kinds of waves while corresponding voice command was recognized.

What are the updated features

We already 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, voice commands are stored in one large group like a library. Any 7 voice commands in the library could be imported into the recognizer. It means 7 commands are effective at the same time.
