AssemblyAI outlines browser voice assistant build in JavaScript

AssemblyAI published a JavaScript tutorial on Oct. 13, 2026, showing how to build a browser voice assistant that listens through the microphone, sends audio over a single WebSocket and plays replies back in the tab. The guide argues that the approach is aimed at conversational assistants rather than simple command-and-response voice controls. In the tutorial, AssemblyAI contrasts the browser’s built-in Web Speech API with its Voice Agent API. The Web Speech API can handle speech recognition and browser text-to-speech, but the company says it leaves understanding logic, interruption handling and LLM integration to the developer.
