How to Build a Chrome-Based Voice Assistant Using JavaScript APIs

A new voice assistant can now be created using only Chrome's built-in APIs. This experimental project combines speech-to-text, text-to-speech, and Google's Gemini Nano AI model to process user input and generate responses. The assistant runs entirely within the Chrome browser, without relying on external servers. While still basic compared to commercial voice assistants, this demonstrates the potential for on-device AI applications using standard web technologies. As these browser-based AI capabilities improve, developers may soon be able to create more advanced voice assistants and AI-powered apps that work directly in the browser.
