### What do you need help with?

Bug report

### Installation method

Manual installation / GitHub

### Issue area

Push-to-Talk

### Impact

Major - a core flow is broken

### Unreal Engine version

5.5

### Convai Unreal Engine Plugin version

v4.27

### Project setup

Blueprint and C++

### Target platform

Other

### Where does it happen?

Not tested yet

### Short summary

Npc will start responding at the slightest break in talking

### What happened?

pressing push to talk does not stop the npc from responding, if the user takes the shortest break or breath it will start responding interrupting the user or causing the user to interrupt the AI. This happens even with push to talk which has a clear trigger for signalling the user is done talking. It also seems like editing the vad settings does nothing as changing them does not help in the slightest.

### What did you expect?

that the npc would only respond after the user releases the push to talk key, or that the vad could be completely disabled/skipped or have the timer be so long it would never actually trigger.

### Steps to reproduce

create a project with convai v4  
add ai  
enable/use push to talk  
talk with a short break between sentences,  
notice the ai attempt to respond.

### I checked the relevant documentation, resources, and similar forum posts before posting.

### I confirm that I did not include API keys, tokens, passwords, secrets, private character data, private conversation logs, or customer data.

[convai push to talk log.txt](https://forum.convai.com/uploads/short-url/6W2iSxIdMDU38zPekyFMrUIq5YJ.txt) (180.6 KB) here are the logs, the character id was “38133e8c-5b69-11f1-a6ed-42010a7be02e”

from what I can tell as well it seems like updating or changing the vad settings in the project settings doesn’t update on the server that’s processing the vad, and therefore it never changes.
