Slides is a visual tool, but the words on each slide still matter. Voice input is fastest in speaker notes and long bullet points where you want a natural spoken tone.
Start voice input
On Mac press the Fn key twice inside the target field.
On Windows press Windows plus H to open voice typing.
On Chromebook enable dictation in Accessibility settings.
Click inside a text box or the speaker notes panel first.
Best fields for voice input
Speaker notes are ideal because they hold whole paragraphs. Titles and bullets work too, but keep them short and edit hard so the slide reads at a glance.
Draft in Zahvox for public copy
For anything you will show to a client or a 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 speaker notes and slide copy in google slides 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 speaker notes and slide copy in google slides 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.
