Sometimes you struggle with spelling a word, or even with typing, and so often we (me anyway) just forget there is usually just a quick button press, or key combo, to activate voice dictation instead of typing.
This is certainly true for the OS's mentioned above, but oddly enough, this is one area where Linux does not really shine (at least not without having to install 3rd party software and set up keyboard shortcuts for it - DeepSpeech and wav2letter++ are possibly worth looking at).

Can’t type a word? Just say it.
