1. Easy to control voice recognition module that simplifies adding voice control to your projects. 2. Command library and simultaneous use: voice commands are stored in groups like a library. All 7 commands in the library can be imported into the recognizer, meaning up to 7 commands can be effective at the same time. 3. Two control options: serial port (fully functional) and general input pin (partial functionality). The board with a general-output interface can trigger multiple actions when a corresponding voice command is recognized. 4. Speaker-dependent voice recognition module: supports up to 80 voice commands in total. Use scenarios - Home and hobby projects: add hands free control to microcontroller projects via the serial interface for simple command-driven actions. - DIY and education kits: teach and prototype voice controlled functionality with a reusable library of commands and a flexible input interface. - Small devices and kiosks: implement speaker-dependent recognition to trigger multiple actions using the board’s general-output capability.
