PowerPoint to Video with Voice Over

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.

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.

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.

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.

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.

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.
