JabberChess is the first speech-activated chess application that allows users to use voice commands to play chess. Users can talk to the app to start a new game (as black or white), play moves or request the location of the pieces on the chessboard. This makes it the first chess application that is truly accessible to visually impaired users. The speech commands use the standard chess algebraic notation to make moves on the chessboard. The app's voice and speech recognition functionalities use software packages from Nuance Communications, a world-leading company in speech recognition technologies and products. JabberChess is also built on top of the open-source Stockfish chess program and engine, one of the strongest chess engines in the world. In other words, visually impaired users can now play chess games against the world′s strongest chess engine on their mobile phones.

For instructions on how to use JabberChess application, please, check the Instructions page.

With the generosity of Nuance Communications, JabberChess is free to all visually impaired users.

I hope to use this first release to gather feedback so that I can improve the application in my future releases. Please, send your valuable feedback to support@jabberchess.chenjackson.com. Thank you!
