## Key facts
- PowerPoint: Insert → Audio → Audio on My PC
- Google Slides: Insert → Audio (MP3/WAV from Drive)
- Best workflow: One narration clip per slide
- Download: MP3 or WAV, no watermark
- Free start: Starter credits
- Demo "Gentle Teacher" (English, MiniMax Speech 2.8 HD): script: Slide three. The water cycle has four stages: evaporation, condensation, precipitation and collection. Let's look at each one.
- Demo "Matilda" (English, ElevenLabs Multilingual v2): script: This quarter, customer sign-ups grew by twelve percent. On the next slide, we'll look at what drove that growth.
- Demo "Explanatory Man" (English, MiniMax Speech 2.8 HD): script: Before you start, make sure your safety badge is visible. In this module, we'll cover the three emergency exits on this floor.

## Steps
1. Write notes per slide — Keep each slide's narration to about 20–60 seconds; start with “This slide shows…” only if it helps.
2. Generate one clip per slide — Paste the notes into the Voice Studio, pick a calm voice (0.9–1.0× speed), download MP3 or WAV.
3. Insert into PowerPoint — Select the slide → Insert → Audio → Audio on My PC → choose the file → Playback: Start Automatically. Tick “Hide During Show”.
4. Or insert into Google Slides — Upload the files to Google Drive → Insert → Audio → pick the clip → set it to play automatically in Format options.

## In depth

### Inserting audio in PowerPoint
PowerPoint adds audio from a file via Insert → Audio → Audio on My PC; for sound that continues across slides there's a Play in Background option [1]. For narration, keep one clip per slide instead, so each slide's audio starts with it and you can update slides independently.

### Inserting audio in Google Slides
Google Slides adds MP3 and WAV files stored in Google Drive through Insert → Audio [2]. Upload all clips to one Drive folder first; the file picker then makes inserting a whole deck quick.

### Writing narration for slides
Narration works best when it:
- Explains what the slide can't — context, the “so what”.
- Stays short — 20–60 seconds per slide.
- Points at the visual — “on the left”, “the blue line”.
- Signposts — “next, we'll look at…” between sections.

## FAQ
Q: How do I add a voice-over to PowerPoint?
A: Generate narration for each slide, then in PowerPoint select the slide and choose Insert → Audio → Audio on My PC, pick the file and set Playback to start automatically. PowerPoint can also record your own narration, but an AI voice needs no microphone or retakes.

Q: How do I add a voice-over in Google Slides?
A: Upload the MP3 or WAV to Google Drive, open the slide, choose Insert → Audio and select the file. In Format options, set it to play automatically.

Q: Can I make the whole presentation play by itself?
A: Yes. Set each slide's audio to start automatically and set slide transitions to advance after the clip's length, or export the presentation as a video.

Q: What audio format should I use?
A: MP3 works in both PowerPoint and Google Slides; Google Slides accepts MP3 and WAV from Drive.

Q: Can I narrate slides in another language?
A: Yes — paste translated notes and pick a voice in that language. MiniMax speaks 40 languages and ElevenLabs Eleven v3 speaks 70.

Q: Is it free?
A: A free Kenerate account starts with free credits — enough to narrate a short deck — with no watermark.
