11Labs Gilfoy voice sounds different

Support Help
1

Hello, we’re seeing issues where the 11labs Gilfoy voice is sounding very very different during a call than it does in preview mode (e.g., doesn’t have an accent anymore, sounds like a completely different voice).

Is this due to some model degradation? Thanks

This issue has been reported before with the 11labs-Gilfoy voice sounding different during actual calls compared to the preview.(1)

One common cause is if you’re using OpenAI’s realtime models (like gpt-4o-realtime), which limits you to only OpenAI voices even if you’ve selected an ElevenLabs voice.(2) If you switch to models like gpt-4o or gpt-4o-mini, you’ll have proper access to ElevenLabs and PlayHT voices.(2)

Another potential issue relates to the voice_model parameter. If you’ve previously set a specific voice model (like eleven_turbo_v2_5) via API, it can cause compatibility issues with certain voices.(3) The voice model setting may persist and affect subsequent calls even when you change the voice.(3)

To troubleshoot:

  1. Check which LLM model your agent is using - make sure it’s not a realtime model if you want to use ElevenLabs voices(2)
  2. If you’ve been updating voice settings via API, try resetting the voice_model parameter first in a separate API call before changing the voice_id(3)
  3. Provide your call ID to Retell support for investigation (similar to the reported case with call_1b760cedd7bd76f4da248ec1701)(1)

If the issue persists after checking these points, I’d recommend reaching out to Retell support with your specific call ID for further investigation.
