Yeah, I know what you mean: I used to think that way and it will probably comes with shame for me too... However, I sort of am changing mindsets now because the situation is that I have to make calls and can not avoid them anymore, or at least, not unless I want to lose my work or feel even more out of the place. This also comes with a lot of shame, possibly much worse than using any sort of technology or trick in the first place. It is not like stuttering does not come with its lot of shame so I would rather take a private shame over a public one, and make life a bit easier as a result. This is definitely not something I would use face to face though. If it gradually allows a PWS to get into solutions he avoids, like making calls, he may feel more opportunities to socialise and get better into putting situations he used to dread, instead of relying on relatives to make calls on their behalf (appointments, etc). Not everything can be recorded beforehand obviously and would have to be said depending on the situation using the normal verbal mechanism. For a lot of stutterers, it is initiating the conversation which is usually the biggest problem and causes the most anxiety: once that moment is passed, things tend to get much better for most...
