Speak to Lichess 2.1

Speak to Lichess is an open source Chrome extension that allows you to dictate moves on Lichess.org. It uses the Web Speech API to interpret voice data and the Lichess Board API to read the board state and submit moves.

Full voice control- where your spoken moves are automatically played without further keyboard or mouse input- is available in Rapid, Classical, and Correspondence time formats. Blitz or faster time formats require some keyboard input and must be in SAN format (https://www.chessprogramming.org/Algebraic_Chess_Notation).

Supports standard games; alternative modes (such as crazyhouse, 'from position', etc.) should support UCI format moves, but are likely to incorrectly process SAN format moves (when submitting with the API).

Check out the 'Using this Extension' section to learn how to effectively dictate moves.

The extension requires English piece names to properly recognize SAN format moves. However, you can use the word correction feature to add piece names in other languages. For example, a Spanish-speaking player could tell the extension that any time it hears 'torre' to instead interpret it as 'rook'. Better foreign language support could come in the future if there's enough interest.

This extension is great for slower time formats and not-so-great for faster formats. It can be a great tool for blindfolded chess. Lichess provides move playback (in most browsers) so that you can hear each move played: enter a game and click on your name in the top right -> sound -> Speech.
