How to Do a Voiceover on PowerPoint
PowerPoint can record your narration or play an audio file per slide. Here is each path, and how to add a natural generated voice.
How to do a voiceover on PowerPoint
Generate the voice in Cantari: paste your script, pick a voice, and generate a natural read in seconds, then export the audio file (MP3 on every plan, WAV on paid plans). No microphone, no retakes.
To insert a ready-made voice file: Insert tab, then Audio, then Audio on My PC, and choose your file.
Click the audio icon on the slide, open Playback, and set it to Start Automatically and (if needed) Play Across Slides.
To record yourself instead: use the Record tab (or Slide Show, then Record) to narrate slide by slide with the timeline.
Inserting an audio file is the cleaner path for a polished deck: generate each slide's narration in Cantari, export the MP3, and insert it on that slide with Start Automatically. No live recording, no room noise, and you can re-generate one slide without re-recording the deck.
