Filler words added to long pauses #1416

Sometimes when processing LLama2 LLM locally, or even cloud base processing for a response can sometimes take longer than expected. On a psychological level, it might be more appealing if the robot adds some filler words or sounds to let the observer know its doing something (processing/thinking)

For example .. Ahhh.. Hmmm.. Uhh.. or "Good Question" if its in response to a question its trying to answer,
"Let me think...." etc.

Additionally, perhaps some movement of eyes and/or head.

implementation could be a loaded response, triggered when a response is taking long
