The speech recognition module is a compact and easy to control speech recognition board. This product is a speech recognition module associated with the speaker.It supports up to 80 voice commands.Up to 7 voice commands can work simultaneously. Any sound can be trained as a command. The user needs to train the module first before any voice commands can be identified.
The board has two control methods: Serial port (Full Function), General purpose input pin( Part of Function).
The general purpose output pins on the board can generate multiple waveforms while identifying the corresponding voice commands.
