Voice-Activated Online Teleprompter

Never worry about manual scrolling speed again. E Teleprompter listens to your natural voice in real time, automatically advancing text as you speak each word and pausing whenever you pause.

How Voice-Activated Teleprompting Works

Traditional teleprompters scroll at a fixed mechanical speed. If you slow down to emphasize a point or answer an audience question, the text rolls away; if you speed up, you run out of text.

E Teleprompter's AI Voice Flow Engine solves this with real-time, zero-lag acoustic and phoneme synchronization:

  • Dual-Channel Unicode & Phonetic Alignment: Combines direct Unicode letter matching with normalized Latin phonetic transliteration. Accurately tracks English, Devanagari Hindi, Sanskrit, and multilingual scripts with full combining mark support.
  • 2-Step Sequential Consecutive Jump Verification: When you deliberately re-read an earlier line above or skip ahead to a line below, the system stages candidate words in the background and smoothly executes the jump only when 2 consecutive words match, completely eliminating accidental single-word homophone jumps.
  • Reverse Step-by-Step Word Highlighting: If you repeat a previous sentence, the active word glow steps smoothly backward word-by-word into the repeated phrase.
  • Zero-Drift Synchronized Pauses: When you pause for breath or slide transitions, scrolling freezes instantly. Ambient room noise and breath are isolated so your pause position stays locked until you speak new words.

4 Intelligent Vocal Energy Modes

Tailor the speech tracking physics to your specific recording format:

1. Continuous Flow

Standard studio mode. Glides smoothly while you speak and decelerates cleanly into stationary hold the moment you pause.

2. Dynamic Speed

Loudness-scaled velocity. Raising your vocal projection smoothly accelerates scroll speed from 0.65x up to 2.2x.

3. Vocal Push

Advances forward in smooth spring line increments per vocal sentence burst — perfect for keynote pauses and bulleted slides.

4. Strict Noise Gate

High-discipline studio noise gate with an aggressive 180ms cutoff for instant, binary stops in noisy environments.

Devanagari Hindi & Multi-Lingual Auto-Detection

E Teleprompter analyzes pasted script content in real time. If 60% or more of your script contains Devanagari characters (Hindi, Sanskrit, Marathi), the speech engine automatically switches to Hindi acoustic recognition (hi-IN), while retaining manual override options in the sidebar.

Hands-Free "OK Camera" Acoustic Keyword AI

In addition to script tracking, E Teleprompter features a dedicated on-device TensorFlow.js acoustic transfer learning engine:

  • Runs 100% client-side via Web Audio FFT spectrogram analysis with zero external server dependencies.
  • Allows you to say "OK Camera" to toggle your webcam and AI gesture vision hands-free without touching your mouse or keyboard.
  • Includes an in-browser Voice Calibration Studio in the sidebar to train 3 quick audio samples for your unique accent and tone.
