I know what you mean. Sometimes I want to find a DIY video, or even get some backstory on a movie, or get info on a TV show coming up, and I have to breace myself as for fingernails on a chalkboard.
There is a guy on Youtube that has been covering the upcoming Wheel of Time series. Even though I’m quite interested in the project, and he’s very well informed as to the going ons, and has even had interviews with some of the people involved, I cannot stand to watch him very often specifically because of his voice.
Most people have no idea how they sound. It actually is a fair amount of work and talent to have a “radio voice”.
It actually is a skill that has to be learned, and it is taught in various journalism or acting classes.
Most people, without training or coaching, come out monotone and boring. Go to a weeding or other event (once covid is over) and listen to people make speeches. Maybe one or two are good, but the rest is a muttering ramble that no one can hear, but no one really cares to hear anyway.
A good speaker, with precise control over pitch, tone, and volume, as well as the knowledge on how to use those most effectively, is going to be far more charismatic and engaging than some random person reading a script, even if the other guy was the one that wrote it (sometimes especially if they were the one that wrote it.)
And that is all assuming that they are using good audio equipment (which is much more affordably priced than say ten or more years ago.) A bad mic can make George Clooney sound like a tinny whiner.
Interestingly, though I cannot find it now, around about a year ago, someone on this board started a thread complaining about how professional radio personalities sound, with their careful enunciation.
