Chess Voice — Hands-Free Chess on Chess.com
Chess Voice is an innovative voice-controlled interface that lets players make moves on Chess.com using spoken commands instead of a mouse or keyboard. It brings a more accessible and interactive way to play online chess — perfect for hands-free play, accessibility support, training, and a fresh experience for chess lovers.
What It Does
With Chess Voice you can:
Speak your moves out loud — say standard chess moves like “Knight f3”, “Pawn to e4”, or “castle kingside”.
Voice input gets processed and executed — the system recognizes your command and plays the corresponding move automatically on Chess.com.
Play games, puzzles, or analysis hands-free — no clicking or typing needed.
This functionality works by using speech recognition to understand coordinate-based chess commands, then applying them directly to the Chess.com board interface, making the game feel more natural and interactive.
Project Overview
Chess Voice is a custom-built voice control SDK developed by EndgameLabz that enables players to interact with online chess platforms using spoken commands. The project was designed to bring hands-free gameplay, improved accessibility, and innovative user interaction to modern chess applications.
At its core, Chess Voice is not just a feature — it is a complete Software Development Kit (SDK) that allows platforms like Chess.com to easily integrate voice-controlled gameplay into their systems.
The SDK converts natural speech into structured chess notation, validates moves in real time, and executes them seamlessly within the game interface.
This project demonstrates EndgameLabz’s ability to combine speech recognition, game logic, and platform integration into a scalable and reusable solution.
