Voice-Activated AI Assistant with n8n and Web Speech API

somdn_product_page

This workflow creates an interactive voice-activated AI assistant that runs directly in a web browser. It combines a user-friendly HTML interface with backend processing in n8n, enabling users to speak naturally and receive voice responses powered by OpenAI’s language and text-to-speech APIs. The process starts with a web-based, clickable orb that triggers speech recognition. Transcribed queries are sent to an AI model, which generates a conversational response. This response is then converted to audio and played back to the user, allowing seamless voice interaction. Ideal for developers and content creators, this setup can enhance digital assistants, customer support, and interactive applications by integrating voice capabilities with AI-driven insights.
