The Geeetech Voice Recognition Module is a sophisticated tool for adding voice control to your projects. It can store up to 15 voice instructions, divided into three groups of five. These instructions are recorded and imported by group via serial commands. With a digital interface supporting 5V TTL level UART and an analog interface for microphones, this module is versatile and easy to integrate. Despite its robust functionality, it is speaker independent, making it less accurate with different users.
