Wolf Munroe ☎I just watched a video about #VocalFry / #CreakyVoice and I have to say, unpopular opinion, perhaps, but I like it.
I think I do it a fair bit as well, as it sounds good to me and means I don't need to say "um" as a filler while I construct the next thing I'm going to say.
Also, I learned in school that varied speech was better than monotonal speech, mostly from the example provided by monotonal teachers.
