Voice Activated Teleprompter for iPhone
Float Teleprompter uses AI speech recognition to follow your voice in real-time. As you speak, the script scrolls automatically — matching your pace, pausing when you pause, and catching up when you speed up. No buttons, no foot pedals, no remote controls. Just your voice.
Most teleprompter apps use a fixed scroll speed. You set the pace before recording and hope your delivery matches. If you pause to emphasize a point or speed up through a transition, the text drifts out of sync. You end up adjusting to the machine instead of the machine adjusting to you.
Voice-activated scrolling flips this dynamic. Float's Smart Scroll uses Apple's on-device speech recognition to listen to what you're saying and match it against your script. The scroll position is driven by your actual spoken words, not a timer. This means the teleprompter adapts to you — not the other way around.
The technical implementation matters too. Speech recognition can be slightly bursty — words arrive in small groups rather than one at a time. Float smooths this with 60fps interpolation, so even when recognition delivers a batch of words at once, the visible scroll movement is buttery smooth. The result feels like the text is floating along with your voice.

Tips from Creators
Speak clearly and at a natural pace for the best tracking accuracy. You don't need to speak slowly — normal conversational speed works great.
If you're in a noisy environment, hold your iPhone closer to your mouth or use a clip-on mic for cleaner voice pickup.
The voice engine works best when your spoken words closely match the script. Small deviations are fine, but large improvised sections may cause the scroll to wait.
Frequently Asked Questions
How accurate is the voice tracking?
Float uses Apple's on-device speech recognition, which is highly accurate for scripted speech. It matches your spoken words to the script text in real-time.
Does it need an internet connection?
No. All speech processing happens on-device. You can use Float completely offline.
What if I go off-script?
Smart Scroll matches what you say to the closest point in the script. If you skip a section or ad-lib briefly, it will catch up when you return to the script text.
Does it work in noisy environments?
It works best in quiet to moderate environments. For noisy settings, speaking clearly and being closer to the microphone helps.
