The Speech Recognition Module with Microphone Voice Control Board brings seamless voice command functionality to modern DIY electronics and home automation systems. Engineered for easy interfacing, the module utilizes a standard 5V TTL UART connection and operates reliably within a 4.5–5.5V voltage range. Its low current requirement (under 40mA) makes it perfect for portable and battery-driven setups. The high recognition accuracy rate—up to 99% in ideal settings—ensures responsive and dependable voice command execution for interactive devices, learning platforms, and smart controls.
This speech module supports both digital (UART) and analog input via a 3.5mm mono microphone or direct microphone pin interface, catering to varied installation needs. Delivered as a complete kit with a microphone and Dupont jumper wire, the module quickly integrates with Arduino and compatible microcontroller boards. Its compact form factor makes it suitable for intelligent gadgets, robotics, and advanced voice-controlled projects.
