Create voice assistant interface with OpenAI GPT-4o-mini and text-to-speech

Voice Assistant Interface with n8n and OpenAI

This workflow creates a voice-activated AI assistant interface that runs directly in your browser. Users can click on a glowing orb to speak with the AI, which responds with voice using OpenAI's text-to-speech capabilities.

Who is it for?

This template is perfect for: - Developers looking to add voice interfaces to their applications - Customer service teams wanting to create voice-enabled support systems - Content creators building interactive voice experiences - Anyone interested in creating their own "Alexa-like" assistant

How it works

The workflow consists of two main parts:

1. Frontend Interface: A beautiful animated orb that users click to activate voice recording 2. Backend Processing: Receives the audio transcription, processes it through an AI agent with memory, and returns voice responses

The system uses: - Web Speech API for voice recognition (browser-based) - OpenAI GPT-4o-mini for intelligent responses - OpenAI Text-to-Speech for voice synthesis - Session memory to maintain conversation context
