Does Notevibes extract speaker notes from PowerPoint?

Yes. When you upload a .pptx file, Notevibes automatically extracts the speaker notes from each slide. These notes become the script for your voiceover, organized slide by slide.

Can I generate voiceover for each slide separately?

Yes. Notevibes creates a slide-by-slide voiceover from your PowerPoint. Each slide's speaker notes are converted to speech individually, with configurable pause markers between slides.

Can I use different voices for different slides?

Yes. Notevibes supports per-slide voice selection. Assign different AI voices to different slides — useful for multi-speaker presentations, Q&A sections, or distinguishing between topics.

Can I use AI voiceover for commercial presentations?

Yes. All voiceovers generated with Notevibes include full commercial usage rights with your subscription. Use them in corporate presentations, sales decks, training materials, webinars, and any business context.

What languages are supported for PowerPoint voiceover?

Notevibes offers 550+ AI voices across 40+ languages including English, Spanish, French, German, Japanese, Korean, Portuguese, Chinese, Arabic, and many more. Create multilingual presentations with native-sounding voices.

Can I download my PPTX with audio already embedded?

Yes. After generating voiceover, click the orange PPTX download button to get your original presentation file with audio embedded per slide. Each slide auto-plays its narration on transition when you enter slideshow mode in PowerPoint.

Does the embedded audio auto-play in PowerPoint?

Yes. Each slide is configured with autoplay timing so the narration starts automatically when you advance to that slide in slideshow mode. This works in Microsoft PowerPoint on desktop.

What audio formats can I download?

You can download your PPTX with audio embedded directly, or download the audio separately as MP3 or WAV. The embedded PPTX option is the easiest — one file, ready to present.

Is the PowerPoint voiceover tool free?

Notevibes offers a free tier to get started. Test all delivery presets, 45+ style modifiers, and per-slide voice control before upgrading to a paid plan for full presentation voiceover production.

How natural does the AI voiceover sound?

Notevibes AI voices deliver natural, human-like speech with professional clarity. Delivery presets like Presentation and Corporate are tuned for clear, engaging narration that sounds like a professional speaker.

Does this work with Keynote presentations?

Yes. Export your Keynote presentation as .pptx (File → Export To → PowerPoint), then upload to Notevibes. Speaker notes are preserved during export and will be extracted for voiceover generation.
