Emotion Controls
Retell AI does offer a voice_emotion parameter that controls the emotional tone of the agent's voice. The available options include: calm, sympathetic, happy, sad, angry, fearful, and surprised.
Other Voice Configuration Options
You can also configure:
- voice_temperature — controls voice stability (0–2 range) , currently applies to 11labs voices
- voice_speed — controls speech rate (0.5–2 range)
- enable_dynamic_voice_speed — adjusts speed based on user's speech rate and context
Regarding ElevenLabs V3 Conversational TTS
I don't have information in my sources about native support for ElevenLabs V3 conversational TTS specifically. For feature requests like this, I'd recommend reaching out directly to the Retell team or posting in the community forums.AI Evy
