How to add an AI voiceover to a PowerPoint presentation
A narrated deck works without you: send it, post it, or turn it into a video. Recording your own voice slide by slide takes many retakes; an AI voice reads every slide evenly, and fixing a sentence means voicing one line again.
This guide shows how to voice each slide with SuperClonica for free, how to insert the audio in PowerPoint so it plays by itself, and how to export the presentation as a video.
Voice the notes of each slide
Write what the narrator should say in each slide’s notes, in short spoken sentences. To try voices, open one in the SuperClonica catalog, paste a sentence of 30 to 100 characters, press the voice button and download it, free and without an account. For a whole deck, install the free engine with python -m pip install superclonica-cpu and voice each slide’s text into its own file: superclonica --text-file slide-01.txt --voice F2 --lang en --normalize --output slide-01.wav. The --normalize option keeps every slide at the same loudness.
Insert the audio in PowerPoint
Select the slide, then choose Insert, Audio, Audio on My PC, pick the slide’s file and choose Insert. On the Playback tab, set Start to Automatically so the narration begins with the slide, and turn on Hide During Show so the speaker icon does not appear. Repeat for each slide. PowerPoint for the web accepts MP3, WAV, M4A, AAC and OGA files up to 16 MB, so a WAV per slide is fine.
Make the slides advance with the voice
On the Transitions tab, set each slide to advance after a time slightly longer than its narration, or rehearse the timings so the deck moves on by itself. A second of silence between slides gives listeners room to breathe.
Export as a video
To share the narrated deck as a video, choose File, Export, Create a Video and keep the option that uses the recorded timings and narrations. The result plays anywhere, including YouTube and learning platforms, without PowerPoint.
