Anyone know if there's a way to use cartesia's experimental controls? This allows you to create much more natural sounding voices with emotion and slow them down for people. If not, it would be amazing if we could have access to this feature. (https://docs.cartesia.ai/user-guides/voice-control) "voice": { "mode": "id", "id": "VOICE_ID", "__experimental_controls": { "speed": "normal", "emotion": [ "positivity:high", "curiosity" ] } }
