Multilingual Voice & Text Telegram Bot with ElevenLabs API and LangChain Agents
This workflow contains community nodes that are only compatible with the self-hosted version of n8n. # Telegram Voice AI Assistant
This n8n template creates a **multimodal Telegram bot** that dynamically responds to users:
- **Replies with voice** when receiving voice messages (using ElevenLabs API)
- **Replies with text** for text-based queries
- Supports **custom AI tools** (e.g., crypto APIs, databases, or custom functions)
Built with **LangChain Agents**, it can integrate any external API or data source into conversations.
## Key Features
**Smart Response Logic**
- **Voice Query? → Voice Reply**
1. Transcribes audio via ElevenLabs API
2. Processes with AI (Groq/Gemini)
3. Converts text response to natural speech (ElevenLabs API)
- **Text Query? → Text Reply**
Bypasses API/API for faster responses
**Extensible AI Tools**
Add your own tools:
- Database lookups
- Weather/stock APIs
- Custom Python functions
- RAG (document retrieval)
Supports **multi-step tool chaining** (e.g., Get BTC price → analyze trends → summarize)
**Language & Context**
- Auto-detects user language (via Telegram's *language_code*)
- Maintains **session memory** (remembers conversation history)
## Use Cases
- **Voice-first customer support**
- **Crypto/analytics assistants** (e.g., What's Ethereum's current gas fee?)
- **Multilingual FAQ bots**
- **Educational tutors** (voice-interactive learning)
## Requirements
- **Telegram Bot Token**
- **ElevenLabs API Key** (For S2S)
- **Groq API Key** or **Google Gemini API Key**
## Customization Tips
- **Change AI personality**: Modify the *systemMessage* in the Voice Assistant node
- **Add more models**: Swap Groq/Gemini for OpenAI, Anthropic, etc.
- **Extend functionality**: Add RAG (Retrieval-Augmented Generation) for document queries
Take this template to create a **Siri-like AI assistant** for Telegram in minutes!
