Vapi is the Voice AI platform for developers.

Vapi AI

You mean with a tool property? I didn't find one. 
I noticed that when tool response is too long we can configure a `ToolMessageDelayed` with a `timingMilliseconds` treshold. But I did'nt see options on `ToolMessageStart` so I could tell the agent to finish its sentence before giving the response

I saw this property in the tools-calling documentation:
https://docs.vapi.ai/tools-calling

```
async: Set to “true” if the function call should be asynchronous, allowing the AI to continue without waiting for the response. Use “false” for synchronous calls.
```

I will force it to false to check if it changes something on my side
