Convert PowerPoint to Audio
Drop a deck and Noty narrates it: every slide voiced from your speaker notes, as one MP3 and as a PowerPoint that plays itself, auto-advancing to the audio.
Drop a .pptx to hear it
Opens the Studio — Noty narrates every slide and hands back the MP3 and the narrated .pptx
Opens in the Notevibes Studio — sign in, drop the file again, Noty does the rest
Three steps, done
Drop the deck
Add your .pptx in the Studio. Exporting from Google Slides or Keynote as .pptx works the same way.
Noty writes the narration from slides and notes
Your speaker notes become the script. No notes? Noty works from the slide text and can write proper notes for you first.
Download MP3 + narrated .pptx
One MP3 of the whole deck, and a .pptx with the audio on every slide that advances on its own when the narration ends.

Before
Slides and speaker notes nobody hears
A deck that only works with you in the room, clicking through and talking over it.
After
Every slide narrated, timed to auto-advance, plus the MP3
A .pptx that plays itself from slide 1 to the end, and one audio file of the whole talk for podcasts, LMS uploads or listening on the go.
Direct it like a voice actor
The Studio is a chat with Noty. Say how the deck should sound — the voice, the pace, the mood, which slide to redo — in plain words, and it produces it.
What gets narrated
Not everything on a slide should be read aloud. This is how the Studio decides what the voice says.
Speaker notes come first
If your deck has speaker notes, they are the narration, slide by slide. It’s the best way to control exactly what gets said.
Slides without notes stay quiet
When some slides have notes and others don’t, the ones without notes get no audio — body fragments read badly next to real narration. Add a line of notes, or ask Noty to write one.
No notes at all? Slide text
A deck with no speaker notes is read from its slide text — titles and body in reading order — and Noty offers to write proper speaker notes from it first.
Images and charts
Visuals aren’t read out. Describe them in the notes — “this chart shows Q3 growth at 18%” — and the voice says it.
Write notes the way you talk
Short sentences, clear points, no jargon. That’s what turns into narration that sounds natural instead of read.
Change one slide, not the deck
Ask Noty to redo slide 7 slower or reword a line. Only that slide regenerates; the rest stays as it is.
Notevibes vs. the other ways to narrate a deck
Recording yourself takes a quiet room and an afternoon of retakes. Most narration tools stop at an audio file. The result you want is a deck that presents itself.
| Notevibes | Record yourself | Other narration tools | |
|---|---|---|---|
| Per-slide narration embedded in the .pptx | Manual | Sometimes | |
| Auto-advance timed to the audio | |||
| Expressive voices with direction | You | ||
| Your cloned voice | Rarely | ||
| MP3 of the whole deck | Manual | ||
| Video export | Soon | Manual | Sometimes |
Drop the deck above and tell Noty how it should sound. It narrates every slide and hands back the narrated .pptx and the MP3.
Voices and languages
The right voice makes or breaks a presentation. The Studio has 30 multilingual Natural voices that speak every language it supports, plus 2,059 native voices across 30 locales for regional accents and character.
Natural voices take direction in plain words — “slower on the numbers”, “warmer at the end”, “whisper this slide” — and only that part regenerates. Or clone your own voice on any paid plan, and every deck sounds like you presenting.
Where narrated decks pay off
Slides without a voice are pictures with bullet points. Audio turns a static deck into something people actually absorb.
Self-paced training: employees learn on their own schedule, without booking a live trainer every time. A warm, conversational voice keeps it from feeling like a lecture.
Async updates and sales decks: send the deck, and it presents itself when the viewer is ready. A confident, measured voice builds trust with prospects.
E-learning modules and conference submissions: students hear the explanation while they see the visuals, and pre-recorded talks are ready without a recording session. Clear, professional delivery holds up over long listening.
Accessibility: narration gives everyone access to the content, not only people reading the slides.
Hear the deck
Drop your PowerPoint and Noty narrates every slide in a natural voice — or yours — then hands back the MP3 and a .pptx that plays itself.

Frequently Asked Questions
How do I convert a PowerPoint to audio?
Drop your .pptx above to open the Notevibes Studio. Noty reads the speaker notes (or the slide text if the deck has none), voices every slide and hands back an MP3 of the whole deck and a narrated .pptx.
Does it read speaker notes or slide text?
Speaker notes first. When a deck has notes, they are the narration and slides without notes stay silent. A deck with no notes at all is read from its slide text, and Noty can write speaker notes from it first.
Can I convert PPTX to MP3?
Yes. You get one MP3 of the whole deck, and a .pptx with the audio embedded per slide that auto-advances when each slide’s narration ends.
What about Google Slides or Keynote?
Export the presentation as .pptx first — both apps have a download-as-PowerPoint option — then drop it in.
Can I change how a slide sounds?
Yes. Tell Noty in plain words — “redo slide 4 slower”, “warmer on the last slide” — and only that slide regenerates.
Can I use the audio commercially?
Yes. Paid plans include a commercial license, so the narration is yours to use in training, courses, videos and client work.
Can it narrate in my own voice?
Yes. Clone your voice once in the Studio (any paid plan) and every deck can be narrated in it.
Can I get a video?
Video export of the narrated deck is coming with the next update. Today you get the narrated .pptx and the MP3.
