+# Multilingual Voice Agent (Voice Agents v1)
+
+Build a voice agent that automatically detects the speaker's language and dynamically switches its TTS voice and system prompt to match — no upfront language selection required.
+
+## What it does
+
+This recipe configures a Deepgram Voice Agent with Nova-3's multilingual STT (`language=multi`) to transcribe speech in any supported language. A `switch_language` function is registered with the LLM so it can signal when the user's language changes. When triggered, the agent dynamically updates its TTS voice and system prompt using `send_update_speak` and `send_update_prompt`, enabling seamless mid-conversation language switching across English, Spanish, and French.
+
+## Key parameters
+
+| Parameter | Value | Description |
+|-----------|-------|-------------|
+| `listen.provider.model` | `"nova-3"` | STT model with multilingual support |
+| `listen.provider.language` | `"multi"` | Enables automatic language detection |
+| `think.provider.model` | `"gpt-4o-mini"` | LLM for the think stage |
+| `think.functions` | `[switch_language]` | Function the LLM calls on language change |
+| `speak.provider.model` | `"aura-2-thalia-en"` | Initial TTS voice (English) |
+
+## Language configuration
+
+| Language | TTS Voice | Prompt Language |
+|----------|-----------|-----------------|
+| English (`en`) | `aura-2-thalia-en` | Reply in English |
+| Spanish (`es`) | `aura-2-thalia-es` | Responde en español |
+| French (`fr`) | `aura-2-thalia-fr` | Répondez en français |
+
+## How language switching works
+
+1. Nova-3 with `language=multi` transcribes speech regardless of language
+2. The LLM detects the user's language from the transcript text
+3. When the language changes, the LLM calls the `switch_language` function
+4. The handler updates the TTS voice and system prompt for the new language
+5. The agent continues the conversation in the detected language
+
+## Example output
+
+```
+Multilingual agent configured (en/es/fr)
+Connection opened
+Event: SettingsApplied
+Switched to es: voice=aura-2-thalia-es
+Received 4800 bytes of agent audio
+Switched to fr: voice=aura-2-thalia-fr
+Connection closed
+```
+
+## Prerequisites
+
+- Python 3.10+
+- Set `DEEPGRAM_API_KEY` environment variable
+- Install: `pip install -r recipes/python/requirements.txt`
+
+## Run
+
+```bash
+python example.py
+```
+
+## Test
+
+```bash
+pytest example_test.py -v
+```
