# Eleven Labs

> Generate speech and sound effects from text using the ElevenLabs API.

**ElevenLabsTools** enable an Agent to perform audio generation tasks using [ElevenLabs](https://elevenlabs.io/docs/product/introduction)

## Prerequisites

You need to install the `elevenlabs` library and an API key which can be obtained from [Eleven Labs](https://elevenlabs.io/)

```bash theme={null}
uv pip install elevenlabs google-genai
```

Set the `ELEVEN_LABS_API_KEY` environment variable.

```bash theme={null}
export ELEVEN_LABS_API_KEY=****
```

## Example

The following agent will use Eleven Labs to generate audio based on a user prompt.

```python cookbook/91_tools/elevenlabs_tools.py theme={null}
import base64

from agno.agent import Agent
from agno.models.google import Gemini
from agno.tools.eleven_labs import ElevenLabsTools
from agno.utils.media import save_base64_data

audio_agent = Agent(
    model=Gemini(id="gemini-2.5-pro"),
    tools=[
        ElevenLabsTools(
            voice_id="21m00Tcm4TlvDq8ikWAM",
            model_id="eleven_multilingual_v2",
        )
    ],
    description="You are an AI agent that can generate audio using the ElevenLabs API.",
    instructions=[
        "Use the `text_to_speech` tool to convert text into natural voice audio.",
        "Use the `generate_sound_effect` tool to create sound effects from text descriptions.",
    ],
    markdown=True,
)

response = audio_agent.run("Generate an audio summary of the french revolution")

if response.audio:
    print("Agent response:", response.content)
    base64_audio = base64.b64encode(response.audio[0].content).decode("utf-8")
    save_base64_data(base64_audio, "tmp/french_revolution.mp3")
```
