It’s a nice engineering approach, but I’m interested in the motivation. Um and ah is distracting in a transcript, where you can naturally pause to take in information; in speech however it can serve as a focusing point to indicate the next part is important. See https://medium.com/better-humans/dont-worry-about-saying-um-... for example. The weirdly obsessive zeal that orgs like Toastmasters have about eliminating them is weird.
Disfluencies aren’t necessarily bad even if the word starts with “dis”!
Occasional ums and ahs are fine but when every other phrase starts with a long aaaaah it can be pretty unpleasant to listen to.
Having heard radio interviews with and without 'internal editing' to remove ums and ahs, most of the time I'd rather the edited version. It's more concise and focused, and I find it easier to comprehend. Too many ums and ahs and my mind wanders, and if it's radio, I can't go easily go back to try again. When I've listened to podcasts or audiobooks, I could never easily go back a little to try again either, and I gave up on them (even though I have some content I really want to listen to, it's too frustrating, so it's not happening). But I'm sure other people have different preferences.
I also don't care for writing that could have been made a lot more concise. It's a lot of work to make things shorter, but I think it's worthwhile.
