For my sins I was once in a Microsoft SQL training session. The guy leading it was great, but at the end of every thought he'd make a noise in his throat, like "uhn" or similar. I couldn't stop noticing it acting like a carriage return at the end of each thought, and hyper-fixated on it to the extent that I learnt precisely nothing.

A team I was on onetime had some French workers and one of them was very helpful, but every sentence had him struggling to think of at least one English word or phrase and he did this weird guttural clearing throat uh-uh-uh-uh-uh sound, like a car backfiring or a lawnmower starting up, instead using an actual filler word or something like "how you say..?"

Nvidia or someone needs to get on a method to filter out the filler words / weird sounds in realtime and failing that automated post processing of saved presentations.
