What languages does VoiceChess support?

VoiceChess supports English, Spanish, and Russian. You can speak your chess moves naturally in any of these languages, and the AI will understand and execute them.

Is VoiceChess free to use?

VoiceChess is free to get started. You can play against the computer (Stockfish), challenge friends, or connect your Lichess account for rated games.

Can I play blindfold chess with VoiceChess?

Yes! VoiceChess offers progressive blindfold training with four visualization modes: normal view, fog of war (see only your pieces), uniform pieces (all pieces look identical), and fully hidden board.

How does voice recognition work in VoiceChess?

VoiceChess uses AI-powered speech recognition to convert your spoken moves into chess notation. Simply say moves naturally like "Knight to f3" or "Castle kingside" and the AI will understand and execute them.

What are the different voice input modes?

VoiceChess offers two input modes: Push-to-Talk (hold a button while speaking) and Auto-Listen (continuous listening that detects when you speak). You can switch between them in the settings.

Which speech recognition engine should I use?

VoiceChess offers multiple speech-to-text (STT) options in Settings: Vosk (offline, works without internet), Whisper (cloud-based, highly accurate), and Browser STT (uses your device's built-in recognition). If you're having trouble with voice recognition, try a different STT engine — some work better for certain languages and accents. Whisper tends to be most accurate but requires internet, while Vosk works offline and is great for privacy.

Can I play against other people?

Yes! You can challenge friends to voice-controlled matches or connect your Lichess account to play rated games against real opponents using your voice.

What is Fog of War mode?

Fog of War is a visualization mode where you can see your own pieces and opponent pieces that you can currently attack. Enemy pieces outside your attack range remain hidden. It's a great intermediate step for blindfold training, helping you practice tracking opponent pieces mentally while still getting tactical cues.

How do I say castling moves?

You can say "castle kingside" or "short castle" for O-O, and "castle queenside" or "long castle" for O-O-O. The same phrases work in Spanish and Russian.

What if VoiceChess doesn't understand my move?

You can enable Move Confirmation in settings to preview moves before they execute. You'll see orange highlighted squares and hear a confirmation beep, then say "yes" to confirm or "no" to cancel and try again.

Does VoiceChess work on mobile devices?

Yes, VoiceChess works in any modern browser with microphone access, including mobile browsers on iOS and Android.

Pro Tips

Move Confirmation

Enable Move Confirmation in settings to preview moves before execution. You'll see orange highlighted squares and hear a beep — say "yes" to confirm or "no" to try again.

Disambiguation

When two pieces can move to the same square, specify the file or rank: "Knight b to d7" or "Rook 1 to e1".

Push-to-Talk vs Auto-Listen

Use Push-to-Talk for noisy environments (hold button while speaking). Auto-Listen works great in quiet spaces with continuous voice detection.
