Dicio is a free and open source voice assistant. It supports many different skills and input/output methods, and it provides both speech and graphical feedback to a question. It uses Vosk for speech to text. It has multilanguage support, and is currently available in English, German and Italian. Dicio answers questions about: search: looks up information on DuckDuckGo (and in the future more engines) - Search for Dicio weather: collects weather information from OpenWeatherMap - What's the weather like? lyrics: shows Genius lyrics for songs - What's the song that goes we will we will rock you? open: opens an app on your device - Open NewPipe calculator: evaluates basic calculations - What is four thousand and two times three minus a million divided by three hundred? Dicio can receive input through a text box or through Vosk speech to text, and can talk using toasts or the Android speech synthesis engine. Interactive graphical output is provided by skills when they answer a question. Each skill can be enabled, disabled or customized using the related settings screen. A dark theme is available. The user input is interpreted by specific, yet reusable, libraries: dicio-sentences-compiler, dicio-skill and dicio-numbers. This app has the NonFreeNet anti-feature because some skills use non-free services to obtain the information requested by the user. You can easily disable unwanted skills or choose alternative services via settings.
