Transcribro is a private, on-device speech recognition keyboard and text service application for the Android platform. It utilizes whisper.cpp to run OpenAI's Whisper series model and integrates Silero VAD for voice activity detection. The app provides a speech input keyboard, allowing users to input text via speech, and can be explicitly used by other applications or set as the user's preferred speech-to-text app. Some applications may use it for speech-to-text conversion. Transcribro's foundation is to offer users a safer and more private speech-to-text solution, avoiding potential privacy breaches associated with cloud processing. The application is open source, enabling users to freely view, modify, and distribute the code.
