XULIA is a comprehensive control system for Windows computers designed specifically to be used by quadriplegic people or people who do not have the ability to move their upper limbs accurately. XULIA allows you to manage all the functions necessary to control all Windows functions using only your voice. As a voice-to-text transcription system, it uses completely free modules combining the Windows SAPI voice recognition libraries for command recognition with Google's cloud-based voice recognition systems indirectly through a Google Chrome browser, which allows you to use Google's paid voice-to-text transcription services completely free of charge. XULIA manages multiple grammars simultaneously with automatic activation to ensure that the set of commands to be recognized is reduced to a minimum at all times, which allows false positives in command recognition to be reduced to a minimum.
