Because Keynote leans on system dictation, everything you learn on one Apple device carries to the others. That makes it a good place to build a voice first slide habit.
Turn on dictation
On Mac press Fn twice inside a text box.
On iPad or iPhone tap the microphone on the keyboard.
Check System Settings for the dictation shortcut and language.
Open the presenter notes panel for longer thoughts.
Slide vs presenter notes
Slides stay tight. Dictate the core phrase, then cut it down to a headline. Presenter notes carry the real script, so speak the way you would in the room and clean it later.
Draft in Zahvox for public copy
For anything shown to a client or public audience, dictate the raw thought in Zahvox, tighten the wording, then paste it back. That extra pass keeps the tone steady and removes filler.
Small habits that keep it readable
Say punctuation out loud, including commas and periods.
Keep one thought per sentence so cleanup is fast.
Do a short review pass at the end of every session.
Save common phrases in a snippet tool so voice input can call them.
Make the setup boring on purpose
The best voice workflows are the ones you stop noticing. Once dictate slide copy and presenter notes in apple keynote works, resist the urge to keep tweaking it. Same mic, same shortcut, same place the transcript lands. Boring is the goal. When the mechanics fade into the background, your attention goes back to the actual thinking, which is the only reason you started dictating in the first place.
Where Zahvox fits after the raw capture
Zahvox is the careful second pass that sits after the raw capture. The browser, the OS, or the app you used for dictate slide copy and presenter notes in apple keynote gave you words on a page. Zahvox at /tool is where you paste those words, tighten the wording, fix the shape of the sentences, and copy the result back into wherever it needs to live. Raw capture anywhere, careful edit in Zahvox — that is the whole loop, and it stays the same whether the source was a laptop, a phone, or a meeting transcript.
