This guide will show you how to design a voice via a prompt using the Voice Design API.

## Using the Voice Design API

:::callout{intent="note"}
This guide assumes you have [set up your API key and SDK](/guides/changelog-eleven-api-quickstart). Complete the quickstart first if you haven’t. To play audio through your speakers, you may also need [MPV](https://mpv.io/) and/or [ffmpeg](https://ffmpeg.org/).

::::::steps
:::::step{title="Make the API request"}
Designing a voice via a prompt has two steps:

1. Generate previews based on a prompt.
2. Select the best preview and use it to create a new voice.

We’ll start by generating previews based on a prompt.

Create a new file named `example.py` or `example.mts`, depending on your language of choice and add the following code:

::::tabs
:::tab{title="Python"}
:::

:::tab{title="TypeScript"}
:::
::::

```python
# example.py
from dotenv import load_dotenv
from elevenlabs.client import ElevenLabs
from elevenlabs.play import play
import base64

load_dotenv()

elevenlabs = ElevenLabs(
  api_key=os.getenv("ELEVENLABS_API_KEY"),
)

voices = elevenlabs.text_to_voice.design(
    model_id="eleven_multilingual_ttv_v2",
    voice_description="A massive evil ogre speaking at a quick pace. He has a silly and resonant tone.",
    text="Your weapons are but toothpicks to me. Surrender now and I may grant you a swift end. I've toppled kingdoms and devoured armies. What hope do you have against me?",
)

for preview in voices.previews:
    # Convert base64 to audio buffer
    audio_buffer = base64.b64decode(preview.audio_base_64)

    print(f"Playing preview: {preview.generated_voice_id}")

    play(audio_buffer)
```
:::::

:::::step{title="Execute the code"}
::::tabs
:::tab{title="Python"}
:::

:::tab{title="TypeScript"}
:::
::::

```python
python example.py
```

You should hear the generated voice previews playing through your speakers, one at a time.
:::::

:::::step{title="Add generated voice to your library"}
Once you’ve generated the previews and picked your favorite, you can add it to your voice library via the generated voice ID so it can be used with other APIs.

::::tabs
:::tab{title="Python"}
:::

:::tab{title="TypeScript"}
:::
::::

```python
voice = elevenlabs.text_to_voice.create(
    voice_name="Jolly giant",
    voice_description="A huge giant, at least as tall as a building. A deep booming voice, loud and jolly.",
    # The generated voice ID of the preview you want to use,
    # using the first in the list for this example
    generated_voice_id=voices.previews[0].generated_voice_id
)

print(voice.voice_id)
```
