Short answer: Google Slides can only voice type speaker notes: open your deck in Chrome, go to Tools, then "Voice type speaker notes," and click the microphone. It cannot dictate slide text. For titles, bullets, and text boxes, use a system-wide dictation tool like Voice Keyboard Pro instead.
Google Docs has had voice typing for years, so most people assume Google Slides has it too. It does, sort of. Slides includes a voice typing tool, but it only works in one narrow place: the speaker notes panel. You cannot use it to dictate a slide title, a bullet list, or any text box on the slide itself. And even the speaker notes tool only works in the Chrome browser on a computer.
That gap matters, because a presentation is mostly slide text. If you want to draft a whole deck by voice, the built-in tool covers maybe a fifth of the work. This guide walks through what Google Slides gives you natively, how to use it properly, and how to dictate everywhere else in Slides on a Mac or an iPhone.
What Google Slides Offers Natively
The built-in feature is called Voice type speaker notes. Here is exactly what it does and does not cover:
- Works: dictating into the speaker notes panel below the slide.
- Does not work: slide titles, body text boxes, bullet lists, shapes, tables, or comments.
- Browser requirement: Chrome on a desktop or laptop. It does not appear in Safari or Firefox, and it is not available in the Google Slides mobile apps.
- Connection requirement: you need to be online, since the speech recognition runs through Google's servers.
Google's reasoning seems practical: speaker notes are long-form prose, which suits dictation, while slides hold short fragments. But in practice people draft decks by brain-dumping content into slides first and tightening later, and that is exactly the phase where speaking beats typing.
How to Voice Type Speaker Notes in Google Slides
If speaker notes are all you need, the built-in tool works reasonably well. Here is the step-by-step:
- Open your presentation in Chrome on a computer.
- Make sure the speaker notes panel is visible. If it is not, go to View → Show speaker notes.
- Click inside the speaker notes area under the current slide.
- Go to Tools → Voice type speaker notes. A microphone panel appears on the left.
- Click the microphone icon. It turns red when listening.
- Speak your notes. Say punctuation out loud: "period," "comma," "question mark," "new line," "new paragraph."
- Click the microphone again to stop.
The first time you use it, Chrome will ask for microphone permission. Click Allow. If you accidentally clicked Block, click the icon to the left of the address bar, find the Microphone setting, and switch it to Allow, then reload the tab.
Limits to know before you rely on it
- It stops when you click away. Switching slides or clicking into the slide canvas ends the session, so you restart the microphone for every slide.
- It times out during pauses. Stop to think for a while and the microphone quietly turns off. Long-form thinkers hit this constantly.
- Punctuation must be spoken. Nothing is inserted automatically, so unedited output reads like one long run-on sentence if you forget.
- Corrections are manual. There is no voice-driven way to fix a misheard word; you grab the keyboard and mouse.
The Real Problem: You Cannot Dictate Slide Text
Try this: click into a slide title, then open the Tools menu. "Voice type speaker notes" is greyed out unless your cursor is in the notes panel. There is no setting to change this. Google simply has not built voice typing for the slide canvas.
So if your workflow is "talk through the deck, get everything down, then design," the native tool leaves you typing the part that matters most. The fix is to stop relying on the app and use dictation that lives at the operating system level, where it works in every text field of every app, including every text box in Google Slides.
Dictate Anywhere in Google Slides on a Mac
A system-wide dictation tool types wherever your cursor is. Google Slides cannot tell the difference between text you typed and text you spoke, so titles, bullets, tables, comments, and speaker notes all just work.
Option 1: Apple's built-in Dictation
macOS ships with basic dictation. Enable it in System Settings → Keyboard → Dictation, then press the shortcut key (F5 or the microphone key on newer Macs) while your cursor is in any Slides text box. It is free and fine for a sentence or two. The trade-offs: accuracy drops on longer passages and technical vocabulary, punctuation handling is inconsistent, and sessions can end abruptly. If Apple's tool misbehaves in the browser specifically, our guide to fixing Mac dictation in Chrome covers the common causes.
Option 2: Voice Keyboard Pro
Voice Keyboard Pro is a menu bar app built for exactly this workflow. You hold a hotkey, speak, and release; the text appears at your cursor, already punctuated and capitalized. Because it works system-wide, the flow inside Google Slides looks like this:
- Click into a slide title. Hold the hotkey and say the title. Release.
- Click into the body text box. Hold, speak your bullets, release.
- Click into the speaker notes. Hold, talk through what you will actually say, release.
- Next slide. Repeat.
No menus, no per-panel restrictions, no browser requirement. It works the same whether you run Slides in Chrome, Safari, or Firefox. A few features are particularly useful for deck work:
- Automatic punctuation. You speak naturally and sentences come out formed, which matters when you are moving fast across dozens of text boxes.
- Smart Vocabulary. A personal dictionary with replacement rules, so your product names, client names, and acronyms come out spelled the way you spell them, every time. If your deck says "Kubernetes" and "EBITDA" a lot, this is the difference between clean output and constant fixing.
- Hold-to-talk control. The microphone is only live while you hold the key, so thinking pauses cost nothing. There is no timeout to race against.
You speak at roughly 130-150 words per minute; most people type around 40. For a content-heavy deck, drafting by voice routinely turns an afternoon of typing into an hour of talking. If you are new to dictating and it feels awkward at first, that is normal and it fades quickly; we wrote up some practical voice typing tips for beginners that shorten the adjustment.
Dictating Google Slides on iPhone and iPad
The Google Slides mobile app has no voice typing feature at all, not even for speaker notes. But on iOS, dictation belongs to the keyboard, not the app, so any keyboard with a microphone works inside Slides.
Voice Keyboard Pro's iPhone keyboard puts a mic button directly on the keyboard. Open the Slides app, tap into any text box or the notes field, tap the mic, and talk. Two extras help on mobile:
- Voice Edit. Spot a mistake after dictating? Speak the change ("change Q3 to Q4") instead of fighting the tiny cursor to fix it by hand.
- Two-way translation. If you present to international audiences, you can dictate in one language and insert text in another, across 24 languages, without leaving the keyboard.
This is handy for the real-world moments deck work actually happens: fixing a title in the back of a taxi, or adding the speaker notes you thought of on a walk.
A Voice-First Workflow for Building a Deck
Dictation changes not just the speed of deck-building but the order. A workflow that works well:
- Talk the outline first. Create empty slides with only titles, dictating each one. Ten titles takes about a minute out loud. This forces the narrative arc before any formatting temptation appears.
- Dictate speaker notes before slide text. Counterintuitive, but effective: talk through what you would say if the slide were on screen right now. That monologue is your content.
- Extract the slide bullets from the notes. Read your spoken notes and pull out the three or four phrases that deserve to be on the slide. Dictate them into the body text box.
- Design last. Layout, images, and theme work is mouse work. Do it once the words are settled so you are not redesigning slides you later cut.
The reason this works: slide decks fail on narrative, not on formatting. Speaking keeps you in explaining mode, where narratives are built, instead of layout mode, where they stall. The same principle applies to slide-adjacent tools; we cover it from other angles in our guides to dictating in PowerPoint on Mac and dictating in Apple Freeform.
Troubleshooting Voice Typing in Google Slides
"Voice type speaker notes" is greyed out
Your cursor is not in the speaker notes panel, or the panel is hidden. Choose View → Show speaker notes, click inside the notes area, then try again. Remember it only appears in Chrome on a computer.
The microphone button does nothing
Chrome was denied microphone access at one of two levels. In Chrome, check the site permission via the icon left of the address bar. On the Mac itself, check System Settings → Privacy & Security → Microphone and make sure Chrome is enabled, then restart Chrome.
Dictation stops after a few seconds of silence
That is the built-in tool's timeout behavior, not a bug on your machine. There is no setting to extend it. A hold-to-talk tool like Voice Keyboard Pro sidesteps it entirely because the mic is only open while you hold the key.
Words come out wrong repeatedly
Names, acronyms, and industry terms are the usual victims. The native tool offers no custom vocabulary. In Voice Keyboard Pro, add the term once to Smart Vocabulary and it is recognized from then on.
Text appears in the wrong place
System-wide dictation types at the cursor, so if you clicked on the slide background rather than inside a text box, there is nowhere for the text to go. Double-click into the text box first, confirm you see a blinking cursor, then dictate.

Frequently Asked Questions
Can I use Google Slides voice typing in Safari or Firefox?
No. The "Voice type speaker notes" tool depends on speech recognition that Google only enables in Chrome. In other browsers the menu item simply does not appear. System-level dictation is browser-agnostic, so if Safari is your home, that is the route.
Can I dictate comments and chat in Google Slides?
Not with the built-in tool, which is locked to the speaker notes panel. With system-wide dictation, yes: comments, replies, and even the file name field are ordinary text inputs, so you can speak review feedback instead of typing it. For a deck with thirty comments to answer, that alone justifies the setup.
Does voice typing work in Google Slides offline?
The native tool needs an internet connection, and so does any cloud-based dictation app, Voice Keyboard Pro included. If you are fully offline, Apple Dictation can run on-device for supported languages, with the accuracy trade-offs noted above.
Can I dictate in languages other than English?
Google's speaker notes tool supports a long list of languages via the dropdown at the top of the microphone panel. Voice Keyboard Pro likewise handles multilingual dictation, and on iPhone it can even translate between languages as you speak, which is useful when the deck is in English but you think in something else. Our guide to multilingual voice typing on Mac goes deeper.
Will dictated text mess up my slide formatting?
No. Dictated text inherits whatever font, size, and color the text box already uses, exactly as typed text would. Templates and themes are unaffected; the words are the only thing that changes.
The Bottom Line
Google Slides gives you real voice typing for speaker notes and nothing for the slides themselves. Use the built-in tool if notes are all you dictate and you live in Chrome. If you want to build entire presentations by voice — titles, bullets, notes, and the comment thread with your reviewer — you need dictation that works at the system level.
Voice Keyboard Pro does exactly that on Mac and iPhone, and the free tier is enough to draft your next deck out loud and see how it compares. Your speaking voice is already two to three times faster than your typing. Slides is one of the best places to spend that speed.
