Hi team @Vapi @Vapi Support Bot @Shubham Bajaj @Kings_big💫 , I would like to know if we can give emotions to our AI assistants when speaking, for example can you tweak voice dialogues to be angry, happy, energetic in align with human emotions. Is this possible ? If yes could you guide me with detailed steps how to implement it

Select a TTS provider like PlayHT or 11Labs that supports emotional tones and configuring the assistant’s voice settings with parameters like “emotion” and styleGuidance in the additionalSettings of the assistant’s voice configuration..

Hi @Kings_big💫 Upon looking into my vapi dashboard I am unable to locate this parameters in additional settings though i tried selecting 11labs and playht. Could you pls specify if there is specific model that offers this a screenshot depicting this settings would be very helpful Thanks

Through the API, as the UI doesn’t expose these controls directly..

can you provide doc for this pls ?

I noticed that the documentation mentions experimentalControls, which includes an emotion option under the createAssistant configuration. From what I understand, this allows us to set a fixed emotion (e.g., positive: high) at the time of creating the assistant. However, I want to clarify my requirement further: I'm looking for a way to have the assistant dynamically adjust its emotional tone during a live call and also reflect the same in the voice. For example, the assistant may start off sounding happy and cheerful, but if the user continues to ask irrelevant or repetitive questions, its tone should gradually shift - perhaps becoming frustrated or stern. Is there a way to achieve this dynamic emotion behavior during a call?

Kinda similar to OpenAI voices? Currently, we don't have it.
