Custom Voices

Custom Voices provide the ultimate solution for creating a unique, consistent, and high-quality voice that perfectly aligns with your brand or application. Unlike Instant Cloning, which creates a direct replica, the Custom Voice process allows you to design a new synthetic voice from audio sample.

This guide covers how to create, use, and manage your Custom Voices.

How to Create a Custom Voice​

The entire creation process is handled through the Audixa dashboard, making it simple to get started.

  1. Navigate to the Dashboard: Log in to your account and go to the Custom Voices page.
  2. Upload Audio: Provide a high-quality audio sample of the voice you want to use as a base.
  3. Define Your Voice: Assign a Name and Gender to your new voice for easy identification.
  4. Get Your Voice ID: Once processed, your new Custom Voice will be added to your library and assigned a unique Voice ID.
note

Creating custom voices is only available via the Dashboard as of now, we are working to add the API endpoint for it.

Using Your Custom Voice on the Dashboard​

To use your new customv voice via the Web Dashboard, you can head to the Text to Speech Page, then select Advance model, and then in the Voices menu, you can find your Custom Voice.

note

Custom voices are only supported in the Advance Model

Using Your Custom Voice in the API​

To use your new voice programmatically, you must reference its unique Voice ID in your API calls and specify the Advance Model.

  1. Find Your Voice ID: Locate your new voice on the dashboard's custom voice section and copy its Voice ID (e.g., custom_voice_123).
  2. Make the API Request: In the body of your POST /tts request, set the voice parameter to your new ID and the model parameter to "advance".
Example POST /tts Request with a Custom Voice
{
  "text": "This audio was generated with our unique and professional brand voice.",
  "voice": "custom_voice_456",
  "model": "advance",
  "speed": 1.0
}

Security and Access​

Your Custom Voices are exclusive to your account.

  • Exclusive Access: Only the account that created a Custom Voice can use its Voice ID.
  • Error on Misuse: If another user attempts to use your Custom Voice ID in their API request, our system will return a 400 Bad Request error with a "detail": "Invalid voice ID" message, ensuring your unique assets remain secure.

Billing​

Creations using a Custom Voice are powered by our Advance Model. All audio generated with a Custom Voice is charged at the same rate as the Advance Model.

Please see our Understanding Credits guide for detailed calculation.

Managing Your Voices​

You have full control over your created voices. Management tasks, such as deleting a Custom Voice, can only be performed through the Custom Voices section of your dashboard.

note

Changing of the voice, or metadata for a custom voice after creation is not allowed
