Voice Design quickstart

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

Using the Voice Design API

This guide assumes you have set up your API key and SDK. Complete the quickstart first if you haven’t. To play audio through your speakers, you may also need MPV and/or ffmpeg.

Make the API request

Designing a voice via a prompt has two steps:

Generate previews based on a prompt.
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:

1 # example.py
2 from dotenv import load_dotenv
3 from elevenlabs.client import ElevenLabs
4 from elevenlabs.play import play
5 import base64
6 
7 load_dotenv()
8 
9 elevenlabs = ElevenLabs(
10   api_key=os.getenv("ELEVENLABS_API_KEY"),
11 )
12 
13 voices = elevenlabs.text_to_voice.design(
14     model_id="eleven_multilingual_ttv_v2",
15     voice_description="A massive evil ogre speaking at a quick pace. He has a silly and resonant tone.",
16     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?",
17 )
18 
19 for preview in voices.previews:
20     # Convert base64 to audio buffer
21     audio_buffer = base64.b64decode(preview.audio_base_64)
22 
23     print(f"Playing preview: {preview.generated_voice_id}")
24 
25     play(audio_buffer)

Execute the code

1 python example.py

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

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.

1 voice = elevenlabs.text_to_voice.create(
2     voice_name="Jolly giant",
3     voice_description="A huge giant, at least as tall as a building. A deep booming voice, loud and jolly.",
4     # The generated voice ID of the preview you want to use,
5     # using the first in the list for this example
6     generated_voice_id=voices.previews[0].generated_voice_id
7 )
8 
9 print(voice.voice_id)
