Yes using a professionally cloned voice directly from ElevenLabs and importing it via the “professional voice” option usually gives noticeably better quality, stability, and more natural tone compared to basic Retell cloning.
On costs: if Retell is using ElevenLabs as the voice provider, you’ll primarily be billed for TTS on ElevenLabs. Retell may still charge for usage (like call minutes or platform fees), but you typically won’t be double-charged for TTS itself.
If you want, I can help you set it up properly and optimize for both quality and cost
