AI Presentation Narrator

The add-on runs where your deck already lives. You install it from the Google Workspace Marketplace and open it from the Extensions menu inside Google Slides, so there is no separate editor to learn. You add a script to the speaker notes and generate a voiceover in one step. The free tier covers up to 10 videos, which is enough to test the workflow before committing to a plan.

The narrator works as text to speech for PowerPoint and Google Slides decks. It reads your script with AI text to speech and syncs the audio to slide changes, so the voice moves on as each slide appears. You avoid the usual chore of splicing separate audio and video tracks or nudging timing by hand. A single consistent take replaces the re-recording cycle that comes with human narration.

You do not have to arrive with a finished script. Plus AI can generate one from the presentation content, and you can edit any line before the final render to fix tone or trim a section. Writing your own script gives the most control, but starting from a generated draft is faster when the deck is already long.

You pick from premium voice models and adjust the speaking parameters so the delivery matches the audience. A training video and a product pitch usually call for different pace and tone, and those settings sit in the same panel where you generate the video. The narrator also supports AI avatars when you want an on-screen presenter rather than audio alone.

Finished narrations come out as video files, which is what makes the tool useful for asynchronous delivery. Instead of a deck someone has to present, you get a file you can post to a site, drop into a course or email to a prospect. The video carries the original slide visuals, so the deck's design stays intact.

The same presentation can be narrated in another language, which matters for teams selling or training across regions. That removes the cost of hiring a separate voice actor for every market, and it keeps one source deck feeding many localized videos.
