A voice-activated teleprompter scrolls your script by following your voice instead of a fixed timer - but there are two completely different versions of "voice-activated," and most apps only do the weaker one. The good news: the real thing is available free in your browser with VoicePrompter. Here's the difference, and why it matters.
The two meanings of "voice-activated"
Both get marketed with the same words, but they are not the same technology:
- Sound detection ("voice sync"). The app listens for sound above a volume threshold. You talk, it scrolls; you go quiet, it stops. It has no idea what you're actually saying or where you are in the script. Some apps even say so plainly in their own docs - "voice sync, not voice recognition… simply detecting audio levels." The problem: the moment you pause oddly, get interrupted, ad-lib, or jump to a different part of the script, it loses you - because it was only reacting to noise.
- Word tracking (real speech recognition). The app follows your actual words and your position in the script. Skip a paragraph, improvise a sentence, or go back to re-read a line, and it stays with you. This is much harder to build - and it's the version that actually feels like magic.
The simple test: if an app only scrolls while it hears noise, it's sound detection. If it follows you when you go off script, it's word tracking.
Why voice scrolling is the only truly hands-free teleprompter
A hands-free teleprompter means no remote, no foot pedal, no reaching for the screen mid-take - and only word tracking actually delivers that. Fixed-speed prompters make you a slave to the motor or force you to keep a hand on the controls; sound-detection apps go hands-free right up until you ad-lib, and then you're tapping the screen to find your place again. With word tracking, your voice is the remote: the script speeds up, waits, and rewinds based on what you say. For solo creators filming alone - nobody behind the camera, prompter out of arm's reach on a tripod - that's the difference between a setup that works and one that ruins takes. VoicePrompter even takes a hands-free "prompter restart" voice command for retakes without touching anything.
Why word tracking is the one you want
Real speaking is never perfectly linear. You pause for emphasis. Someone asks a question. You decide to say your third point first. With sound detection, every one of those moments risks the text marching on without you - or stopping dead. With word tracking, the script just follows your voice, at your pace, in your order. VoicePrompter even scrolls backward: start reading an earlier line and it moves back to it. And you can tap any word to jump the prompter straight there.
How to get real voice scrolling - free
The free VoicePrompter web app does genuine voice scrolling right in your browser. No download, no account, no cost:
- Follows your voice in 34 languages, auto-detected, all processed on your device - your script never leaves your browser.
- Works offline. Install it as an app (PWA) on iPhone, Android, Mac, or Windows and it keeps working with WiFi off - handy when you're filming somewhere with spotty internet.
- Mirror mode for teleprompter glass, landscape lock on iOS, active-word highlighting, and a hands-free "prompter restart" voice command for when you're filming alone.
- A deliberately minimal interface: paste your script and go.
Get started in under two minutes
- Open voiceprompter.app on your phone or browser.
- Paste your script.
- Bump the font size up (bigger than you think - at filming distance you want to read without squinting) and give yourself generous line spacing.
- Tap the microphone to turn on speech recognition.
- Start talking.
For Mac: the version that's invisible on screen share
If you record on a Mac and need the text to stay invisible during screen sharing - Zoom, Google Meet, Teams, OBS - and float on top of every app, the native VoicePrompter for Mac adds that, plus a more advanced engine and 60+ languages. One reviewer put it simply: "the most robust, reliable, versatile and customizable one I've tried… it follows them word for word." More on that in best teleprompter app for Mac.
