Yeah my work is remote and I use this trick every time I speak. It's annoying cause when work was in person my boss would always say I need to work on fixing my stutter and now that it's gone (it's not, only due to this trick) I did a good job of "relaxing and focusing on what I want to say". So annoying and patronizing. But anyways sorry for the rant yes this trick does in fact work. It's also why deaf people don't stutter ever
