About This Workflow
Overview
This workflow enables you to create an AI-powered voice chat application. It leverages n8n nodes to handle incoming voice messages via a webhook, manage conversational context using memory nodes, process speech-to-text with OpenAI, generate AI responses with Google Gemini, and convert the AI's response back into speech using ElevenLabs.
Key Features
- Real-time voice input via webhook.
- Contextual conversation memory management.
- Speech-to-text transcription using OpenAI.
- AI response generation with Google Gemini.
- Text-to-speech conversion using ElevenLabs.
- Flexible and customizable integration.
How To Use
- Configure Webhook: Set up the n8n webhook node with your desired path (e.g.,
/voice_message). - Set up Credentials: Configure credentials for OpenAI, Google Gemini, and ElevenLabs in n8n.
- Configure ElevenLabs API Key: In the 'ElevenLabs - Generate Audio' node, set up your ElevenLabs API key in the generic authentication parameters.
- Set Memory Manager: Configure the 'Window Buffer Memory' node with a session key (e.g., 'YOUR_CREDENTIAL_HERE') to manage conversation history.
- Configure LLM: Set up the 'Google Gemini Chat Model' and 'Basic LLM Chain' nodes with your desired prompts and model.
- Connect Nodes: Ensure proper connections between nodes, especially the 'Aggregate' node for context and the 'Limit' node to control the conversation length.
- Trigger Workflow: Send a POST request with voice data to your n8n webhook URL.
