Voice Interfaces in Flutter: Building Assistants with Speech-to-Text and Text-to-Speech

Voice is becoming one of the most natural ways to interact with technology, and Flutter gives us the tools to bring it into our apps today. In this session, we’ll explore how to build a voice-enabled assistant in Flutter by combining Speech-to-Text (STT) for recognition and Text-to-Speech (TTS) for natural responses. We’ll cover the available Flutter plugins and APIs, compare cloud vs. offline solutions, and highlight pitfalls like dealing with Austrian dialect.
Through live demos, you’ll see how to integrate STT and TTS into a Flutter app, structure your architecture for responsive voice interactions, and design UIs that feel intuitive when voice becomes the primary input. By the end of the talk, you’ll have the knowledge to extend your Flutter apps with conversational capabilities—whether for accessibility, productivity, or full-blown voice assistants.
