Hi Team, Call ID's: b85693fb-4ea1-46df-a847-b51bd0851a23, 9dd7d736-a511-4503-9d69-c2dbefd8c063, 001be82d-09b4-4417-a576-aed781a7c1ee, 41343d7a-b523-49b4-9ebb-3944fed60a8a Timestamp: 6 Aug 2025, between 03:30 PM to 06:00 PM IST. Expected response: We expected the voice output to match the quality and modulation of the official Hume AI voice samples available at: https://platform.hume.ai/voices?page=0. Specifically, we used the same voice in Vapi that performs well on Hume’s platform What we actcually got: The voice output in Vapi had poor modulation and sounded unnaturally slow compared to the version on Hume AI’s own website. The same voice model that works smoothly and at a natural pace on Hume AI was speaking extremely slowly when used in our Vapi voice agent. Thanks for your help. @User @Kings_big💫

Hey Priyanshu, thanks for sharing your details. Our team will look into it and get back to you soon with an update.

If possible, Please keep me posted!

Hi, Please switch the LLM to another model or provider for troubleshooting purposes. Sometimes, the LLM can cause slow and distortion in the voice. Let us know if this issue continues after modifying the configuration and provide the new call ids so we can review it.
