AI Voiceover for PowerPoint
Drop your .pptx and Noty voices every slide from your speaker notes. Get the PowerPoint back with the narration embedded, timed to auto-advance — plus an MP3 of the whole deck.
Drop a .pptx to add a voiceover
Opens the Studio — Noty voices every slide and hands back the narrated .pptx
Opens in the Notevibes Studio — sign in, drop the file again, Noty does the rest
Three steps, done
Drop your PowerPoint
Add the .pptx in the Studio. Noty takes the speaker notes from every slide as the script — or the slide text when there are no notes.
Choose the voice and the tone
Say how it should sound — a confident presenter, a patient trainer, a keynote on the main stage — and in which language.
Download the narrated .pptx
Your original deck with audio embedded on every slide, each one auto-playing and advancing on its own. The MP3 comes with it.

Before
A silent deck with speaker notes
Any .pptx you already have. Notes help; a deck without them still works.
After
Every slide narrated, timed to auto-advance
Your PowerPoint with the voiceover embedded slide by slide — press play in slideshow mode and it presents itself.
Direct the voiceover in plain words
The Studio is a chat with Noty. Say which deck, what it should sound like and what you want back — the narrated .pptx, the MP3, or one slide redone.
Why add an AI voiceover to your presentation
Narrated slides are easier to share than silent decks, and they land even when you can’t be in the room.
Hours of recording, gone
No microphone, no retakes, no audio editing. Change a slide and redo just its narration instead of re-recording the deck.
One deck, many languages
Voice the same deck in another language with a native voice — sales pitch in the prospect’s language, training for every office.
Consistent on every slide
No background noise, no vocal fatigue, no accidental “um”. Slide 40 sounds like slide 1.
More accessible presentations
Audio makes a deck usable for people with visual impairments, reading difficulties, or anyone who takes information in better by listening.
Direction in plain words
Boardroom calm, product-demo energy, a warm instructor, a webinar that feels live — describe the delivery and Noty voices it that way.
The voiceover lives in the file
No manual audio insertion: every slide carries its own clip and timing, so the .pptx you send is the presentation.
AI voiceover vs. the alternatives
PowerPoint has a built-in recorder. Here is how it compares to having Noty voice the deck.
| Notevibes | Record Slide Show | Other voiceover tools | |
|---|---|---|---|

How to add an AI voiceover to a PowerPoint presentation
Drop your .pptx into the Studio. Noty takes the speaker notes from every slide and uses them as the narration script, slide by slide — no copy-pasting, no reformatting. No notes yet? It reads the slide text, or writes notes for you first if you ask.
Next, tell Noty how it should sound. “Confident and engaging”, “a patient instructor”, “main-stage keynote energy” — the delivery is a request in plain words, not a preset menu. Hear it before the whole deck is voiced.
Then approve, and every slide is narrated. Download your original PowerPoint with the audio embedded per slide: in slideshow mode each slide plays its narration and advances when it ends. The whole deck also comes as one MP3 for anywhere a .pptx doesn’t fit.
That replaces recording yourself in PowerPoint, hiring a voice actor, or hours of manual audio syncing. Whether it’s a quick internal deck or a client presentation, the steps are the same: drop the deck, describe the voice, download.
Who uses automated voiceover for PowerPoint
L&D and training teams narrate onboarding decks, compliance modules and process training at scale — one voice, one tone, every module, without booking a recording session.
Sales and marketing teams send narrated pitch decks that prospects review on their own time, so the pitch lands without a live presenter. Webinar slides become on-demand content.
Educators turn lecture slides into narrated lessons students can replay at home. Conference speakers send a narrated version of the talk to events they can’t attend in person.
Your slides, with a voice
No recording studio, no voice actors, no manual audio insertion. Drop the deck and download it narrated.

Frequently Asked Questions
Does it use my PowerPoint speaker notes?
Yes. Drop the .pptx in the Studio and the speaker notes from each slide become the voiceover script, slide by slide. A deck without notes is read from its slide text.
Is the voiceover generated slide by slide?
Yes. Each slide gets its own narration, with a natural pause at every slide change, and each clip is embedded on its own slide.
Can I download my PPTX with the audio already embedded?
Yes. Ask for the narrated .pptx and you get your original presentation with the voiceover embedded on every slide — no manual audio insertion.
Does the embedded audio auto-play in PowerPoint?
Yes. Each slide is timed so its narration starts when the slide appears and the deck moves on when it ends, in PowerPoint slideshow mode on desktop. Other presentation apps may handle embedded audio differently.
Can I get just the audio?
Yes. The whole deck comes as one MP3, ready for a video editor, an LMS or a podcast feed.
Can I change one slide without redoing the deck?
Yes. Edit the slide’s notes or ask Noty to redo that slide in a different tone. The rest of the voiceover stays as it is.
What languages can the voiceover be in?
Ask for the language you need and Noty picks a native voice for it — the same deck can be voiced in several languages.
Can the voiceover be in my own voice?
Yes, on every paid plan. Clone your voice once in the Studio and every deck is narrated in it.
Can I use AI voiceover in commercial presentations?
Commercial usage rights come with every paid plan.
Is the PowerPoint voiceover free?
New accounts get free credits to try it. Narration uses credits by the amount of text voiced.
Does this work with Keynote presentations?
Yes. Export from Keynote as .pptx (File → Export To → PowerPoint) and drop that file in the Studio. Speaker notes survive the export.
