Transcript
In this section, we will review the three metrics that matter most for the quarter and what they tell us.
Decks are read more than presented
Most PowerPoint content is consumed async—shared before meetings, used in training, revisited on demand. Narration turns a static deck into a self-running briefing. The problem is recording it: a 40-slide deck is hours of mic time, and any edit means starting over.
Where TTS helps decks
- Training material that runs on its own for new hires.
- Sales and investor decks with a consistent voice track.
- Internal comms where the author would rather not record themselves.
- Localized decks generated in multiple languages from one script.
- Conference or booth loops that play unattended.
The narration workflow
- Write slide notes or a script in the Voxly studio.
- Pick a clear, neutral narrator voice.
- Generate per-section audio and place clips on the matching slides.

Making deck narration sound professional
- One voice per deck. Consistency reads as polish.
- Short segments. Generate per section so edits stay localized.
- Add pauses between slides for a natural rhythm.
- Match tone to audience. A calm voice for board decks, a brighter one for internal kickoffs.
Inserting audio in PowerPoint
The exported MP3 drops onto a slide like any media:
- Insert the audio on the matching slide.
- Set it to play on click or automatically.
- Trim silences so timing matches your transitions.
- Test the deck start to finish once before sharing.
Localized decks without a second recording
A deck that sells in English can ship in Chinese from the same notes. Native Chinese presets avoid the translated-layer accent. Generate per-section audio per language and swap the track—no new scriptwriting, no new recording session.
Rights and cost
Commercial rights are included on the paid plan. Flat $19.9 per month means updating a deck never costs extra. Compare options in Best AI Voice Generators 2026.
Common pitfalls
- One giant audio file - generate per section so edits don't force a full redo.
- No voice consistency - lock one narrator per deck.
- Ignoring the mute button - let viewers toggle audio; don't autoplay loudly in meetings.
- Skipping the full run-through - always play the deck once with audio before sharing.
