Controls

Narration that fits a deck

Presentations need a calm, steady pace.

  • Speed · 0.5× – 2×

    MiniMax voices. 1× is the natural pace; 0.85–0.95× suits narration and learners, 1.1–1.2× suits ads and recaps.

  • Pitch · −12 to +12

    MiniMax voices, in semitones. A few steps down sounds bigger and older; a few up sounds lighter and younger.

  • Emotion · 7 moods

    MiniMax: neutral, happy, sad, angry, fearful, disgusted, surprised — the same words, a different read.

  • Interjections & tags · (laughs) · [whispers]

    MiniMax 2.8 reads 13 cues like (laughs), (sighs), (breath); ElevenLabs Eleven v3 reads audio tags like [whispers], [excited], [sarcastic].

  • Stability · 0 – 1

    ElevenLabs. Lower = more expressive and varied between takes; higher = steadier and more even.

  • Output · MP3 · WAV · FLAC

    MiniMax lets you pick the format and sample rate (16–44.1 kHz); every clip downloads without a watermark.

  • Summary

    To sum up: start early, check twice, and ask for help when you need it.

Tips

Better narrated decks

The slides and the voice should work together.

  • One clip per slide — changing one slide never means re-recording the deck.

  • Keep slides simple; the narration should explain, not read the slide aloud word for word.

  • Set audio to start automatically and hide the icon during the show.

  • Use Transitions → After to advance slides when each clip ends, or export the deck as a video.

  • Name files by slide number (slide-03.mp3) so inserting is fast.

  • Use one voice and the same settings for the whole deck.

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.
