What you get
Who reads presentations aloud?
More people than you'd think. Any time someone needs a presentation to speak for itself, AI narration fills the gap.
Trainers creating e-learning
Turn slide decks into narrated training modules. No studio, no scheduling, no retakes.
Sales teams automating demos
Send a narrated product deck instead of booking another call. Prospects listen on their own time.
Educators making lessons accessible
Students who learn by listening get a narrated version of every lecture. Accessibility wins.
Speakers rehearsing talks
Hear your slides read back to you. Catch awkward transitions and wordy bullets before you step on stage.
Students reviewing slides
Commute? Gym? Eyes tired? Let the AI read your study slides. Retention goes up when you combine visual and audio.
Managers sharing async updates
Narrated slide decks replace half the meetings nobody wanted. Your team listens when it suits them.
How it reads your slides
Not every slide is built the same. Here's how AI handles the different parts of your PowerPoint.
Speaker notes first
If a slide has speaker notes, those become the narration script. They were written to be spoken, so they sound the most natural. The visible slide text is skipped — your audience hears the full version, not the shorthand.
No notes? Slide text, naturally
When there are no speaker notes, the AI reads the visible text: title first, then subtitle, then bullet points top to bottom. It pauses between sections so listeners can follow along.
Bullet points handled smoothly
Nobody wants to hear "bullet, bullet, bullet." AI reads bullet lists as a flowing sequence with natural pauses. Short bullets get connected into sentences. Long bullets are read as separate thoughts.
Voices & Languages
Your presentation, your voice — well, almost. Pick from 550+ AI voices across 57 languages and make it sound like you rehearsed for hours.
550+ voices
Male, female, young, mature. Conversational, professional, warm, commanding — you name it.
57 languages
English, Spanish, French, German, Japanese, Chinese, Arabic, Hindi, Portuguese, and 48 more.
Preview first
Listen to any voice before generating. Adjust speed, pitch, and tone until it sounds right.
PowerPoint narration options
Three ways to add voice to your slides. One takes minutes, one takes hours, one takes your budget.
| Record Yourself | AI Narration | Hire VO Talent | |
|---|---|---|---|
| Time | 2-4 hours | 5 minutes | 3-7 days |
| Cost | Free (your time) | From $19/mo | $200-$500+ |
| Consistency | Varies by take | Perfect every time | High (pro talent) |
| Languages | One (yours) | 57 languages | One per talent |
| Edits & revisions | Re-record | Regenerate in seconds | Extra cost |
| Quality | Depends on mic | Broadcast-ready | Studio-quality |
Recording yourself works if you have a quiet room and patience. Hiring talent works if you have budget and time. AI works right now — and you can always re-generate when the deck changes.

Questions?
How do I read a PowerPoint aloud with AI?
Upload your PPTX file at notevibes.com/powerpoint-voiceover. The AI extracts text from every slide, picks up speaker notes, and generates natural narration. Choose a voice, hit generate, and download the audio as MP3.
Does it read speaker notes or the slide text?
Both, but speaker notes take priority. If a slide has speaker notes, those become the narration. If not, the AI reads the visible slide text — title, subtitle, bullet points — in natural reading order.
How long does it take to narrate a full deck?
A 20-slide presentation typically takes 2-3 minutes to process. Shorter decks finish in under a minute. You can preview individual slides before generating the entire presentation.
What file formats can I upload?
Notevibes accepts .pptx files (PowerPoint 2007 and later). If you have an older .ppt file, open it in PowerPoint or Google Slides and save as .pptx first.
Can I use a different voice per slide?
Yes. You can assign different voices to different slides — useful for panel-style presentations or when slides cover different topics that benefit from a change in tone.
What audio quality do I get?
Audio is generated as high-quality MP3. Voices are powered by neural TTS engines from Google, Amazon, Microsoft, and OpenAI — the same technology behind modern voice assistants.
Can I use the narration commercially?
Yes. All paid plans include full commercial usage rights. Use the narrated audio in e-learning courses, sales decks, YouTube videos, webinars, or any other purpose.
What languages are supported?
Notevibes supports 57 languages including English, Spanish, French, German, Portuguese, Japanese, Chinese, Korean, Arabic, Hindi, Russian, and many more. Each language has multiple voice options.
Is there a slide limit?
No hard limit on the number of slides. The narration length depends on how much text is in your slides and speaker notes. Plans are based on character count, not slide count.
Can I edit the narration after generating?
Yes. If a slide sounds off, tweak the text or speaker notes and regenerate just that slide. No need to redo the entire presentation. Changes take seconds, not hours.
Your slides, out loud
Upload your PowerPoint and hear it come alive. AI picks the best way to read each slide, narrates everything, and hands you an MP3. That simple.
