Narrated presentations, finished in minutes

Recording your own voice for a 30-slide deck is a three-hour commitment. FreeTextoSpeech turns speaker notes into studio-quality narration in a few minutes. Perfect for async team updates, conference pre-records, sales demos, board decks, and training materials.

How to narrate a PowerPoint in 5 steps

  1. Copy the speaker notes from slide 1.
  2. Paste into FreeTextoSpeech, pick a voice (Jessica or Nicole for corporate tone), generate.
  3. Download the WAV and rename it slide-01.wav.
  4. In PowerPoint go to Insert → Audio → Audio on My PC and place the clip on slide 1.
  5. Set playback to Automatically, hide the speaker icon, and repeat for each slide.

Voices for corporate and education decks

  • Jessica — polished, professional, the default for corporate presentations.
  • Nicole — clear and trustworthy, ideal for training content.
  • Michael — authoritative male voice for board updates and keynotes.
  • Kore — precise articulation for technical or data-heavy decks.

Export to video

Once narration is embedded, use File → Export → Create a Video in PowerPoint (or File → Download → Microsoft PowerPoint and open in PowerPoint from Google Slides) to produce an MP4 with synchronized AI voiceover. Upload to YouTube, an LMS, or share as an MP4 file.

FAQ

Frequently Asked Questions

01 How do I add FreeTextoSpeech audio to PowerPoint?
Generate and download your WAV, then in PowerPoint choose Insert → Audio → Audio on My PC. Select the WAV and drag the speaker icon off-slide so it does not show during presentation.
02 Can I use this for Google Slides too?
Yes. Google Slides does not accept WAV directly; upload the WAV to Google Drive, then Insert → Audio → pick the file. Alternatively convert WAV to MP3 with any free converter and upload that instead.
03 Will my narration auto-play when the slide loads?
Yes, if you set the audio Playback to Automatically or In Click Sequence in PowerPoint. Hide the speaker icon for a clean presentation.
04 Is there a character limit per slide?
FreeTextoSpeech accepts 5,000 characters per request, which is plenty for a typical slide. Generate one WAV per slide and place each on its own slide.
05 Can I use this for training videos exported from PowerPoint?
Yes. Once the audio is embedded, use PowerPoint's File → Export → Create a Video option to produce a training MP4 with your AI narration baked in.
