Hume AI voice Integration: Poor modulation and Voice Slowness
Hi Team,
Call ID's: b85693fb-4ea1-46df-a847-b51bd0851a23,

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.

Hey Praveen 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.
