npx skills add elevenlabs/skills --skill voice-isolator

Using the Voice Isolator API

1

Create an API key

Create an API key in the dashboard here, which you’ll use to securely access the API.

Store the key as a managed secret and pass it to the SDKs either as a environment variable via an .env file, or directly in your app’s configuration depending on your preference.

.env
ELEVENLABS_API_KEY=<your_api_key_here>
2

Install the SDK

We’ll also use the dotenv library to load our API key from an environment variable.

pip install elevenlabs
pip install python-dotenv

To play the audio through your speakers, you may be prompted to install MPV and/or ffmpeg.

3

Make the API request

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

# example.py
import os
from dotenv import load_dotenv
from elevenlabs.client import ElevenLabs
from elevenlabs.play import play
import requests
from io import BytesIO
load_dotenv()
elevenlabs = ElevenLabs(
  api_key=os.getenv("ELEVENLABS_API_KEY"),
)
audio_url = "https://storage.googleapis.com/eleven-public-cdn/documentation_assets/audio/voice_with_background.mp3"
response = requests.get(audio_url)
audio_data = BytesIO(response.content)
audio_stream = elevenlabs.audio_isolation.convert(audio=audio_data)
play(audio_stream)

Then run it:

python example.py

You should hear the isolated voice playing through your speakers.
