ELECHOUSE Voice Recognition Module is a compact and easy-control speaking recognition board. It supports up to 80 voice commands in all. Product package contains the voice recognition module and a compatible microphone.

- Maximum 7 voice commands effective at same time

- Arduino library is supplied
- Easy Control: UART/GPIO
- User-control General Pin Output



Users need to train the module first before using it to recognizing any voice command. Training includes recording voices and writing what the module should send via serial pins when a voice is recognized. Any sound could be trained as command. That means it's not language dependent. After training it will only activate by the voice of the trainer, not another person even if he says the same words.
