Voice AI assistant in browser with conversation memory

This workflow delivers a click-to-activate voice assistant directly in the browser. It captures user speech via Web Speech API, processes it through an AI agent (GPT-4o-mini) with session memory, and returns spoken responses using OpenAI Text-to-Speech. The entire system runs on webhook triggers within n8n, making it ideal for embedding into websites, support portals, or interactive content.

## Who it´s for
- Developers adding voice interfaces to applications
- Support teams building voice chatbots
- Content creators exploring interactive voice experiences
- Product owners aiming to deploy a custom voice assistant

## What the automation does
- User clicks an interactive orb and speaks their query
- Speech is captured via the browser’s Web Speech API
- Transcribed text is sent to a LangChain agent powered by GPT-4o-mini with memory
- Response is generated with context awareness and converted to audio via OpenAI TTS
- Audio file is returned to the browser and played back instantly
- Conversation history is preserved across interactions for natural dialogue flow

## What´s included
- Ready-to-use n8n workflow with LangChain and OpenAI integration
- Webhook trigger and session management logic
- Integrations with OpenAI API and Web Browser (Web Speech API)
- Basic HTML page with UI and client-side JavaScript
- Text guide for deployment and customization

## Requirements for setup
- n8n instance (cloud or self-hosted)
- OpenAI API key
- Web server or static hosting for the frontend HTML
- Modern browser supporting Web Speech API (e.g., Chrome, Edge)

## Benefits and outcomes
- Fast deployment of a voice interface without full-stack development
- Context-aware conversations for more natural user experience
- Flexible use from prototypes to production systems
- Customizable voice and AI behavior via OpenAI settings
- Independence from proprietary platforms like Alexa or Google Assistant
- Low technical barrier for non-developers when using the template
- Native integration with existing tools via n8n’s ecosystem
