Why am I getting "Internal Server Error" during TTS cloning?

Last updated: March 3, 2026

Context

You may encounter an "Internal Server Error. We are looking into this." message when attempting to use the TTS (Text-to-Speech) cloning feature. This error typically appears with a studioEventId and indicates a temporary backend issue.

Answer

The "Internal Server Error" during TTS cloning is usually caused by temporary backend issues or high server load. Here's how to resolve it:

  1. Wait and retry: Wait 10-15 minutes and try the same TTS cloning operation again. Most cases resolve automatically after this waiting period.

  2. If the error persists: Contact support with the following information:

    • A screenshot of the error message

    • The exact timestamp when the error occurred (including your timezone)

    • Details about which voice/script you're using and the cloning method

    • The studioEventId from the error message

This information will help the support team investigate the specific issue and provide a targeted solution.
