Why am I getting "The voice may violate ElevenLabs Terms of Service" error during TTS?

Context

When using Sync's text-to-speech (TTS) feature, you may encounter an error message stating "The voice may violate ElevenLabs Terms of Service and requires verification. Please try with a different voice or contact support." This error prevents you from generating audio using certain voices or content.

Answer

This error originates directly from ElevenLabs, our TTS provider, not from Sync itself. ElevenLabs automatically flags voices or content that may violate their Terms of Service, which can include:

  • Voices of famous personalities or public figures

  • Content that is harmful or inappropriate

  • Voices that imitate restricted or copyrighted material

To resolve this issue, you have two options:

Option 1: Use Different Voice or Content

  1. Try using a different voice sample that doesn't violate ElevenLabs' terms

  2. Modify your script content if it contains inappropriate material

  3. If cloning a voice, try using a different audio sample until the error no longer appears

Option 2: Use External TTS Service

  1. Generate your audio using a different TTS service or platform

  2. Import the generated audio file into Sync

  3. Use Sync for lip-sync functionality only
