Upload your existing PowerPoint (PPTX, PPT), Google Slides, PDF, or create a presentation with AI. SlideSpeak's AI reads every slide and prepares a narration script for your video.
Pick from 50+ natural-sounding AI voices across 20+ languages. The AI writes a narration script for each slide. Edit or regenerate any line before recording.
SlideSpeak syncs voiceover to slides with smooth transitions. Preview your video, then download as HD MP4 or share via link. You're ready for YouTube, LMS, or social media.
The AI reads each slide, writes a clear and concise narration script, and generates a natural-sounding voiceover. Edit any line, swap voices, or regenerate, then export a presentation-ready video with perfectly synced audio.
As we review the data, notice the steady growth trend across all regions.
These results reflect consistent teamwork and strategic focus over time.

The renewable energy sector is thriving with innovative solutions. Next-gen solar panels are more efficient and durable, while new wind turbine designs effectively capture energy and lower costs. Advanced batteries improve storage and reliability, and smart grids integrate diverse renewable sources, accelerating our path to a sustainable energy future.
Narration, captions, pacing and quality are yours to set, and nothing is locked once the video exists.
Turn captions on at generation time. They come from the same script that produced the audio, so the text matches the speech word for word.
Drop [break], [long-break] and [emphasis] into the script to control pauses and stress, so the delivery lands where you want it.
Confident, calm, excited, friendly, empathetic, inspiring, serious or soft. The same voice, delivered for the material.
Generate in HD when the video is going onto a big screen or into a learning platform rather than a chat thread.
A scrubbable timeline, a cue-by-cue caption preview, and per-slide audio you can regenerate without rebuilding the whole video.
Share a finished export with a link. Whoever you send it to can watch it without creating an account.
Synthetic narration is usually sold on speed. That is not why the people who depend on it choose it. When your captions have to be right, a generated voice transcribes cleanly the first time. Your own recording rarely does.
From professional and authoritative to warm and conversational. Find the perfect voice for your audience. Preview each voice before generating your video.

Record a sample once and your voice narrates every deck you build after that, including in languages you don't speak.
Translation runs on the slides and the narration. The deck comes back as an editable PPTX with layout, fonts and brand colours untouched.
Quiz slides inside the deck, a package your LMS can import, or a live game in the room.
Question and answer slide pairs built from what is already on the slides. They stay part of the presentation and export with it, so a deck you hand over arrives complete.
Export the questions as a QTI 1.2 zip for Canvas and Schoology, as SCORM alongside the deck, or as a Question Library CSV for D2L Brightspace.
A real-time game your audience joins by scanning a QR code. Answers score by speed and the leaderboard updates on screen. Nobody has to create an account.
The output is a real file, not a page on our site. Open it, send it, or upload it wherever your organisation keeps things.
A standard, fully editable presentation file. Open it in PowerPoint, Keynote or Google Slides and carry on working.
For handouts, attachments and anywhere a file needs to look identical on every machine that opens it.
SCORM for the deck, QTI 1.2 for the quiz, and a Brightspace CSV where that is what the platform accepts.
