It supports English and Chinese. You can freely set your own wake word, commands and responses to them. The audio signal is trained and learned on a neural network. The implementation allows up to 150 offline commands. Power supply is possible via microUSB port or 5V pin on the board. The module has five I/O pins of its own or you can connect it to the board via the UART bus.
