Text to Speech for PowerPoint

1. 01

   Upload the PPTX

   The studio extracts each slide’s speaker notes, falling back to readable slide text when notes are absent.

2. 02

   Review and generate

   Edit or remove slide sections, choose a voice and format, then generate the selected narration queue.

3. 03

   Download clips + manifest

   Get one named clip per slide in a ZIP and a CSV placement manifest, or download the joined narration.

4. 04

   Repeat & export to video

   Repeat for each slide. Then File → Export → Create a Video to bake narration into a training MP4.

  Embed per slide via Insert > Audio

  Generate one WAV per slide rather than a single track for the whole deck. PowerPoint: Insert > Audio > Audio on My PC, drop on the slide, set Start: Automatically, tick Hide During Show. Per-slide audio means re-recording one slide stays a one-slide change, the rest of the deck is untouched.

• 02

  Sync narration to slide transitions

  In the Animations pane, set the slide advance to "After" with the duration matched to your WAV length plus 0.3s of breathing room. PowerPoint shows the audio length on the timeline, round up. For builds and bullet reveals, place each on a click trigger and use the audio cue points to fire animations on time.

• 03

  Export as MP4 with embedded audio

  File > Export > Create a Video. Pick "Use Recorded Timings and Narrations" so PowerPoint bakes per-slide audio into the MP4. For HD output choose 1080p; 4K balloons file size for marginal gain on slides. Exported MP4s play anywhere, LinkedIn, YouTube, Vimeo, internal LMS, without requiring PowerPoint at the other end.

• 04

  Watch file size on large decks

  WAV at 24 kHz runs roughly 3 MB per minute. For shared decks, choose MP3 directly in the studio; the file is much smaller with little perceptible loss for narration. Or distribute the final MP4 instead of the editable deck.

• 05

  Build kiosk-mode loops for trade shows

  Slide Show > Set Up Slide Show > Browsed at a kiosk (full screen). Set every slide to advance after the audio finishes plus a short pause. The deck loops on its own at the booth, no operator. Pair with Bella or Sarah on a clean voice, no music underneath, so the booth audio stays intelligible in noisy halls.

  Pacing tricks via punctuation

  The model respects punctuation as pacing. Commas add a short pause; periods longer; ellipses... slightly longer still. For dramatic bullet pacing, separate ideas with periods rather than commas. For acronyms, write them spaced ("A P I" reads as letters; "API" may read as "ay-pee-eye"). Test, listen, regenerate, at zero cost per regeneration this is cheap to iterate.
