V3.1 - Voice Recognition

Workers in loud factory environments can use voice commands to log data or control machinery without removing safety gear. Implementation: Getting Started with V3.1

This module is frequently used in DIY hobbyist projects where simple vocal triggers are needed: voice recognition v3.1

: It can store up to 80 voice commands (each approximately 1500ms1500 m s or 1–2 words long). Workers in loud factory environments can use voice

The module, primarily manufactured by Elechouse , is a compact, speaker-dependent board designed for easy integration with microcontrollers like Arduino. Unlike cloud-based systems, this hardware-based solution processes voice commands locally, providing high recognition accuracy without an internet connection. Core Technical Specifications
