Speak Recognition Voice Recognition Module

Speak Recognition Voice Recognition Module



ELECHOUSE Speech recognition module is a compact and easy to control speaker recognition board Speak Recognition Voice Recognition Module.

 Input voltage: DC 4.5-5.5V .

Any sound can be trained as a command. Use need to train the module before they can make it recognize any voice commands.

Size: 31x50mm.

It supports up to 80 voice commands in total. Up to seven voice commands can work simultaneously.



Speak Recognition Voice Recognition Module

Overview



ELECHOUSE 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 command. Use need to train the module fit before let it recognizing 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.

On V2, voice commands are separated into 3 groups while you training it. And only one group (5 commands) could to 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 recognizer. It means 7 commands are effective at the same time.
