I am using Charlotte(Native) voice currently. But she talk too fast. So I am going to control speed in voice configuration but her voice speed never change. How can I change her voice speed?

Based on the information I found, voice speed control depends on the provider used for Charlotte(Native). Try switching to a different voice provider that offers better speed control:

{
  provider: 'openai',  // Offers up to 4x speed control
  voiceId: 'alloy',    // Replace with preferred voice
  speed: 0.5          // Lower values for slower speech
}

If this doesn't work, you might need to contact Vapi support as some voices have limitations with speed control.

Provider is "playht"

checking if this is resolved/solved for you?

Im having the same problem with 11labs, openai and vapi voices, changing the "Speed" does nothing. The only thing that changes speed is which voice model is used (11labs turbo, multilingual, flash...) and the Stability also changes the voice speed a lot.

Hey! To help track down this issue, could you share: - The call ID - What response you expected to get - What response you actually got instead This would really help us figure out what went wrong!
