A big part of natural-sounding Retell agents comes from good prompt design, turn-taking, and voice settings rather than just the voice itself. Using natural fillers sparingly, varying sentence length, allowing brief pauses, handling interruptions well, and choosing the right TTS voice can make a huge difference.
I've worked on Retell voice agents and can help optimize your conversation flow, prompts, and voice configuration so the calls feel much more human and less robotic.
