Dicio is a free and open source voice assistant for Android that focuses on strong privacy by running its understanding and response generation directly on the device whenever possible. It supports multiple input and output methods, including hotword-based voice input using the Vosk speech-to-text engine and a graphical interface for users who prefer to tap instead of talk. The assistant is built around a flexible “skills” system that lets it respond to a wide variety of requests such as search, weather, navigation, calculator, timers, media control, and more. It offers rich multilingual support and is already available in a wide range of languages including English, Spanish, German, French, Italian, Russian, and others. The project integrates tightly with a custom “sentences language” and compiler so each language can define its own natural phrasings to trigger skills without sacrificing accuracy.
