How to get speech output as text from screen readers

Sometimes you need text, rather than voice, output from screen readers. Why? It's really useful for bug reports ("this disclosure icon is announced as 'black dash triangle dash filled dash x2 underscore final dot png' and needs alt text"). Luckily, getting this text is easy to do.

VoiceOver on MacOS

In VoiceOver you press Option + Control + Shift + C to have the last item that was announced copied to the clipboard. Bonus feature: pressing Option + Control + Shift + Z to save the last phrase to the desktop as an audio file.

VoiceOver on iOS

A three-finger quadruple tap copies the last announcement to the clipboard.
