Interactive AI Voice Assistant with n8n and Langchain
detail.loadingPreview
Empower your team or customers with a custom AI voice assistant interface built entirely within n8n. This workflow provides a browser-based UI for speech recognition and leverages Langchain for intelligent query processing, delivering a responsive, interactive experience.
About This Workflow
This n8n workflow creates a sophisticated, full-stack AI voice assistant. It begins by serving a dynamic HTML user interface directly from an n8n webhook, featuring a visual 'orb' that indicates listening and speaking states. The client-side JavaScript handles speech-to-text using native browser capabilities. Transcribed queries are then sent back to n8n via another webhook, where a Langchain agent processes the natural language input. While the final audio response generation is a logical next step (and expected by the UI), this template lays the robust foundation for building interactive voice-driven applications with minimal code.
Key Features
- Browser-Based Voice Interface: Deploy a stylish, interactive voice UI directly from an n8n webhook.
- Client-Side Speech-to-Text: Utilizes native browser speech recognition for real-time transcription of user queries.
- AI-Powered Query Processing: Integrates with Langchain agents for advanced natural language understanding and response generation.
- Dynamic UI Feedback: Visual cues (orb animations) clearly show listening, processing, and speaking states to the user.
- Full-Stack Orchestration: Manage both front-end serving and back-end AI logic entirely within n8n.
