@User can we add these to the api payload for cartesia to add emotion :

"voice": {
  "mode": "id",
  "id": "VOICE_ID",
  "__experimental_controls": {
    "speed": "normal",
    "emotion": [
      "positivity:high",
      "curiosity"
    ]
  }
}

-->https://docs.cartesia.ai/build-with-sonic/capability-guides/control-speed-and-emotion

We will add to Vapi once these features are stable.
