Features

Reads your speaker notes, not your bullets

Speaker notes are already written to be spoken, so they make far better narration than reading slide fragments aloud. Decks without notes fall back to slide text.

Every slide held for exactly its own narration

Slide timing is measured from the generated audio, so a dense slide stays up while it is being explained and a title slide does not linger. Fixed-duration exports either cut the voice off or leave silence.

Neural voices in ten languages

Narration is generated in the language of your deck, including Arabic, Hindi, Indonesian, Urdu, Spanish, French, German, Portuguese and Turkish.

Adjustable pace

Choose a slower delivery for technical material or a faster one for a recap, without re-recording anything.

A real MP4 that plays anywhere

H.264 video with AAC audio at 1920×1080 — uploads straight to YouTube, an LMS, Teams or LinkedIn with no conversion step.

Turn a PowerPoint deck into a video with an AI voice over. Upload the .pptx and the narration is generated from your speaker notes — which are already written to be spoken — while each slide is held on screen for exactly as long as its own narration takes. That last part is the whole difference. Exporting a deck to video gives you a silent slideshow with a fixed number of seconds per slide, which is why a silent export is something you can already do in PowerPoint and never had a reason to pay for. With narration, fixed timing is actively wrong: a dense slide gets cut off mid-sentence while a title card sits in silence. Here the audio length sets the slide length, so the video tracks what is being said. Decks with no speaker notes fall back to reading the slide text. Narration is produced in the language of your deck across ten languages including Arabic, and you can slow the pace down for technical material. Output is a standard H.264 MP4 at 1920×1080 that uploads straight to YouTube, an LMS or Teams. Try without sign-up.

Frequently Asked Questions

How is this different from your PowerPoint to Video tool?

That one produces a silent slideshow with a fixed number of seconds per slide — the same thing PowerPoint's own Export to Video does. This one generates an AI voice over from your notes and times each slide to its narration. If you want a silent animated export, use the other page; if you want something someone can actually watch and learn from, use this one.

Where does the narration text come from?

Your speaker notes, by default, because those are already written as spoken prose. If a slide has no notes, the slide's own text is read instead, which is serviceable but reads like bullets because it is bullets. For the best result, write a sentence or two of notes per slide before converting.

Can I use my own voice instead?

Not on this page — the narration is synthesised. If you have already recorded audio inside the deck, PowerPoint's own Export to Video preserves it, which is the better route for a deck you have personally narrated.

Which languages are supported?

English, Arabic, Spanish, French, German, Portuguese, Hindi, Indonesian, Turkish and Urdu, using neural voices. The language is detected from your deck's text, and Arabic decks get an Arabic voice rather than an English voice reading Arabic words.

How long does a conversion take?

Roughly proportional to the deck: every slide is rendered, narrated and encoded. A ten-slide deck is usually under a minute; a hundred-slide deck takes several. The video is assembled in one pass, so you wait once rather than per slide.

What if narration cannot be generated?

You still get the video, and the result says plainly that it was rendered without narration rather than quietly handing you a silent file. That way you know to retry rather than discovering it after uploading.
