Voice Recognition Module Key benefits Robust voice command support: can store and recognize up to 80 distinct voice profiles or commands; multiple profiles can be activated simultaneously. Each voice profile must be enrolled before recognition. recognition accuracy: up to 99 percent detection accuracy for reliable performance in real projects. Flexible interfaces for easy integration: digital UART interface with 5V TTL level for GPIO, and an analogue option using a 3.5 mm mono connector plus pin header. Versatile control modes: serial fullfunction mode and universal input partialfunction mode to fit different system requirements. General purpose output pins can generate different signal types while the corresponding voice command is recognized. Readytouse kit: includes 1 Voice Recognition Module and 1 compatible component, giving you the core parts needed to begin training and implementing voice commands in your project. Specifications Power: 4.55.5V supply; current consumption about 40 mA Digital interface: UART and 5V TTL level for GPIO Analogue interface: 3.5 mm mono connector plus pin header Detection accuracy: 99% Control and operation details Control modes: serial (full function) and universal input (partial function) Output behavior: general output pins on the board can generate different types of signals while recognizing the corresponding voice command Complete kit contents 1 x Voice Recognition Module 1 x compatible component 23 practical use scenarios Smart home control: use enrolled voice profiles to operate lighting, climate control, or security systems without pressing buttons. Educational robotics: send voice commands to a robot for basic movements or task execution, enabling hands control during development. Industrial automation: gate or equipment control via voice commands to improve operator workflow while reducing touchpoints. Notes Enrollment of voice profiles is required before recognition. Compatible with systems using UART/TTL GPIO and analogue 3.5 mm mono interfaces.
