AI Voice for Presentations: Slide and Demo Narration Fish Audio
Narrate slides, demos and training decks people can watch on their own time — with updates that regenerate one line instead of the whole recording. Start from $9, one-time packs, no subscription.
A presentation that can be watched on its own time does three jobs at once: it survives time zones, it works as a sales asset, and it becomes onboarding material the day after it is recorded. Narrating it used to cost a booking with a voice artist and a re-record every time a number changed. With the script as the source of truth, the narration updates the way the deck does — one slide at a time.
This guide covers the narrated-deck workflow, updates, and the rights that apply when the audience becomes a client.
Why narrated decks beat live-only
- Async review. Sales decks, investor update videos and product walkthroughs get watched when the viewer has time — no calendar coordination, no missed meetings.
- Training at scale. A narrated deck is a course module; the e-learning guide covers the deeper production loop for full modules.
- One voice, many decks. The library narrator you lock in becomes part of the brand; switching voices between decks is what makes a company sound like several companies.
- Legal review moves earlier. Because the script is text, compliance or legal can read the exact words before a single minute is generated — cheaper than reviewing finished audio.
The narrated-deck workflow
- Write speaker notes as the script. One segment per slide or per group of slides; read it aloud once to catch anything you would not say out loud.
- Pick the narrator once. A calm, clear read fits almost every deck; the voice library tags voices for business narration. For founder-led decks, clone the presenter voice instead — with consent and rights in place.
- Generate segment by segment. Slide-aligned segments make updates trivial later; a typical deck is 1 to 2 credits in total.
- Assemble the export. Drop segments into the deck tool or video editor, and re-export — the download guide covers how the audio files leave the workspace.
Updating without re-recording
The maintenance model is the point: scripts, voices and segments are all saved, so an update is a regeneration, not a recording session. Changed slide, changed number, new ending slide — each regenerates alone, at about one credit per 1,000 characters. Decks stay current without the audio going stale, which is what usually happens to recorded narration a quarter after launch.
What does a narrated deck cost?
| Deck size | Characters | Approximate cost |
|---|---|---|
| 10-slide deck | ~1,200 | 1 to 2 credits |
| 30-slide deck | ~3,600 | 4 credits |
| 60-slide training | ~7,000 | 7 credits |
A full deck sits far inside one $9 Starter pack. Packs are one-time purchases, credits stay valid for 12 months, and there is no subscription. Client deliverables and monetized material need the $29 Creator pack for commercial usage rights — the commercial use guide covers what each pack includes.
Frequently asked questions
Can I narrate a deck without recording my own voice?
Yes. Paste the speaker notes as the script, pick a narrator voice and generate each segment — no recording session needed.
What happens when the deck changes?
Regenerate the changed segment, not the whole recording. Because scripts and voices are saved, fixing one slide costs about one credit per 1,000 characters.
Is it appropriate for client presentation work?
Yes, with the right pack: client deliverables need commercial usage rights, which start with the $29 Creator pack. Internal decks are covered by the $9 Starter pack.
Can the narration match our brand voice?
Either keep the same library voice across every deck, or clone the presenter voice from a 15 second recording — with consent and rights in place — so updates keep their sound without their calendar.
What does a narrated deck cost?
A typical deck is 1 to 2 credits; a long training deck is about 7. The $9 Starter pack holds 1,000 credits, so decks sit far inside one pack.
