FAQ

How do I get an API Key?

1. Register an Account at ElevenLabs.
2. Click on the image on the top right.
3. Click on "Profile"
4. Show the API Key and copy it

How do I get a voice id?

After registering an account and having a paid subscription, you can create your own custom voice on the website.
If you don't want to use a custom voice, you can use the default voices. You can find the IDs for the default voices by using the ElevenLabs.getVoices() method.
If you want to use a custom voice, you can use the ElevenLabs.getCustomVoiceIds() method to get the IDs for your custom voices.

Something doesn't work. What should I do?

1. Check if you have the latest version of the package installed.
2. Did you follow all the steps at the beginning of this Readme?
3. Did you enter your API Key correctly?
4. Did you enter the correct voice ID?

If you did all the above and you are sure it's a problem with the package, please contact me on Discord, via E-Mail or create an issue.
