Let sound add a touch of character to your projects! Connect the speech recognition module, add a few simple lines of code, and your project can understand what you say. No need for machine learning, no need for a specific person's voice, no need to connect to the Internet, speech recognition can be performed anytime, anywhere, combined with the speech synthesis module, speech dialogue can also be realized. It uses the Gravity I2C interface for communication, which is compatible with most master controllers, and is very suitable for access to educational scenarios. Three voice recognition modes and three voice input modes enable the module to be integrated into more scenarios.
