Google Slides Teleprompter: Free Extension That Scrolls With Your Voice

SyncVocal is a free Chrome extension that turns your Google Slides speaker notes into a teleprompter. It floats over your slides, scrolls as you speak, and moves to the next slide when you finish the last line. This guide covers setup, settings, and how to present with it.

Why You Need a Teleprompter for Google Slides

Google Slides has speaker notes, but they're stuck at the bottom of your screen in presenter view. This creates problems:

• Breaking eye contact — Looking down at notes instead of at your audience/camera
• Awkward positioning — Notes are far from where you're looking
• No voice sync — Manual scrolling disrupts your flow
• Small text — Hard to read from distance
• Can't reposition — Stuck in presenter view layout

A dedicated teleprompter solves all of these problems by putting your speaker notes in a floating window that you can position anywhere, with automatic voice-synced scrolling.

Best Practices for Google Slides Teleprompter

Writing Effective Speaker Notes

• Write how you speak — Use contractions, short sentences, conversational language
• One idea per slide — Don't cram too much into one note section
• Mark pauses — Use [PAUSE] to remind yourself to breathe
• Highlight key points — Use CAPS or bold for emphasis
• Include transitions — "Now let's move on to..." helps flow

Positioning the Teleprompter

• Near your camera — 1-2 inches below webcam lens
• Eye level — Don't look down
• Comfortable distance — 2-3 feet away for easy reading
• High contrast — Dark background, light text (or vice versa)

Using Voice Sync During Presentations

• Speak clearly — Enunciate for better recognition
• Moderate pace — Not too fast, not too slow
• Quiet environment — Reduce background noise
• Test beforehand — Do a practice run to calibrate
