A carousel can live as photos. The same sequence can live as a Reel, a Short, or a TikTok if someone talks through it. Most people never make the video version because they think it requires a microphone, a script rewrite, and a quiet hour they do not have.
You already wrote the argument on the slides. Voiceover is that argument at speaking speed.
Script from the headlines, not from a blank page
Read the on-image headlines out loud. If a line is awkward in your mouth, it is awkward in a voiceover. Shorten it. Then add one spoken sentence per slide that a headline cannot hold — the example, the caveat, the “this is what I mean.”
Do not narrate what the viewer can already read. Duplicate audio plus duplicate text is how people swipe away. Use the voice for tone and the extra beat; use the slide for the claim.
A useful check: mute the video. Does the deck still make sense? Now play only the audio. Does it still make sense? If both fail, the script is a caption dump.
Keep the take imperfect on purpose
Studio-clean AI voices that never breathe sound like an ad. A slightly shorter pause, a normal talking pace, and words you would actually say will outperform a theatrical read. If you generate narration, pick a voice that matches the account — calm and direct, not radio-sales.
Edit the script before you generate audio. Regenerating a 40-second read because you hated one clause is slower than fixing the clause.
Same campaign, second format
The mistake is treating “the carousel” and “the video” as two projects. They are one campaign with two outputs. When the slides change, the voiceover should change with them — not live in a separate doc that drifts.
Export when the sequence is done: photos for the networks that want a swipe, MP4 for the networks that want a watch. You should not rebuild the story to get a talking version.
SlidePress keeps the voiceover with the slides so the video is a button, not a second production. If you already have a spoken script, paste that instead of a topic — the deck should sound like you, not like a blog outline.
