Avatar speaking random things on it's own in the new SDK.

Hi, I started using the new sdk today. First of all, the heygen team has done a great job with reducing the latency of streaming.task api. However, it tends to speak random sentence after every 15 seconds, even if streaming.task api is in action?

This behavior is really sabotaging the user experience overall. Is there a potential fix around this, or do you guys have it in the list of improvements/features to ship with the latest release of SDK. Please let me know. Prompt reply would be much appreciated.
