The is a compact, easy-to-use speaker-dependent voice recognition board. Unlike AI-driven cloud services (such as Google Assistant or Siri) that process continuous language, this hardware module is designed to listen for specific, pre-programmed vocal commands.
Equipped with a 3.5mm microphone jack and comes bundled with a high-sensitivity analog microphone. Operating Voltage: 4.5V to 5.5V DC. Current Consumption: Less than 40mA.
So, what makes Voice Recognition V3.1 so special? Here are some of its key features:
It can load and recognize up to 7 voice commands simultaneously in a single group. voice recognition v3.1
Voice Recognition Module V3.1 is a compact, speaker-dependent board designed for microcontrollers like Arduino and Raspberry Pi. It allows you to control hardware projects using custom voice commands without needing an internet connection. Key Features of Version 3.1 Command Capacity : Supports up to 80 voice commands Simultaneous Recognition : Can process up to 7 active commands at once from its internal library. Training Flexibility

For simple, non-critical voice control tasks in a quiet environment, the Elechouse V3.1 provides a fun, educational, and very affordable introduction to the world of embedded speech recognition.
Voice Recognition v3.1 changes how developers add voice control to their apps. By combining acoustic and language modeling, dropping processing latency, and optimizing for edge hardware, it delivers a smooth, conversational user experience. It provides a private, secure, and accurate platform built for modern computing requirements.
Doctors use V3.1 for hands-free clinical documentation. The system’s high accuracy with complex drug names reduces the time spent on electronic health records (EHR). Here are some of its key features: It
For developers and enterprises, adopting is straightforward, though it requires a shift in thinking.
Because it processes speech locally rather than sending audio data to the cloud, it is highly prized for projects that require offline functionality, low latency, and enhanced privacy. Core Specifications at a Glance 4.5V to 5.5V (Standard TTL logic level). Current: Interface: UART (Serial) and GPIO lines. Baud Rate: 9600.
