Voice Sync helps your teleprompter move with your delivery instead of forcing you to speak at a fixed scrolling speed. You can slow down, pause, improvise, or skip a line, and ScrollVox keeps the script close to where you are speaking.

Quick answer: prepare short spoken paragraphs, grant microphone access, place the active line near the lens, and run a 30-second test before the real take. Speak normally rather than trying to “feed” the recognizer. If you go off script, return with a clear phrase that also appears in the next written line.

This guide uses the current ScrollVox workflow. The exact position of a control can move between app versions, but the preparation, calibration, and recovery process stays the same.

What Voice Sync does

Traditional auto-scroll asks you to follow the screen. Voice Sync reverses that relationship: ScrollVox listens for the words in your script and advances as you say them.

That means you can:

  • pause to breathe or emphasize a point;
  • change your pace between sections;
  • recover after a short improvisation;
  • skip ahead without manually finding your place.

Voice Sync works best when the spoken delivery stays reasonably close to the written script. Small changes are natural, but rewriting entire paragraphs while recording can make any voice-following system work harder.

1. Prepare a script for speaking

Write for the ear, not for the page. Use short sentences, everyday words, and visible paragraph breaks. If one sentence is difficult to say in a single breath, split it.

Read the script aloud once before recording. This quickly reveals phrases that look fine in writing but feel unnatural when spoken.

A clear script is the most important part of a natural teleprompter setup.

2. Open your script and choose Voice Sync

Open the script in ScrollVox, enter the prompting view, and select the voice-following option. Allow microphone access if iOS asks for permission. The microphone is needed so the app can match your speech to the script.

Position the prompt window as close to the camera lens as practical. Keeping your eye line near the lens makes the delivery feel more direct.

Before the full take, check three things:

  1. iOS shows ScrollVox as allowed under microphone privacy settings;
  2. the intended microphone can hear a normal speaking voice at the recording distance;
  3. the script displayed in the prompting view is the final version you plan to say.

If you are also using a meeting, camera, or recording app, test the whole combination—not just ScrollVox by itself. A configuration that works in a quiet script preview can behave differently after the device position or audio route changes.

3. Set comfortable reading controls

Before recording, adjust the text size, line spacing, prompt width, and highlight position. The best settings let you understand a line at a glance rather than reading word by word.

A useful starting point is:

  • large enough text to read without leaning forward;
  • short lines that do not require wide eye movement;
  • two or three upcoming lines visible;
  • the active line close to camera level.

Treat these as starting conditions, not universal numbers. Sit or stand in the real recording position, look at the lens, and check whether you can understand the active line with a small glance. If your eyes travel sideways, narrow the text area. If you lean forward, increase the type size. If every transition surprises you, reveal one more upcoming line.

Do not optimize for the most words on screen. A compact, predictable reading area usually gives you better eye contact than a dense page of small text.

4. Speak naturally and let the script follow

Start with your normal speaking voice. Do not speed up to “help” the teleprompter. Finish thoughts, use pauses, and look into the lens at the end of important sentences.

If you need to improvise, keep the added thought concise and return to a recognizable phrase in the script. ScrollVox can then match your position and continue.

Run a 30-second calibration take

Use the opening paragraph and deliberately include four events:

  1. speak one sentence at your normal pace;
  2. pause for two seconds;
  3. repeat a short phrase;
  4. add one unscripted sentence, then return to the next written sentence.

Watch the prompt, but also review the recording. A technically successful scroll is not enough if your eyes are visibly scanning or your voice becomes unnatural. Adjust one variable at a time—script wording, prompt width, active-line position, or microphone distance—and repeat the same test.

You can check the planned duration and adjust the speaking-pace control with the free video script timer. The goal is not to force a particular speed; it is to spot a large difference between the script you planned and the pace you can deliver comfortably.

5. If the script loses your place

First, say the next written phrase clearly. If the room is noisy, reduce background sound or move the device closer. Also confirm that ScrollVox has microphone permission and that the correct input is active.

For a difficult section:

  1. shorten long sentences;
  2. remove repeated phrases;
  3. add a paragraph break before the transition;
  4. rehearse the first few words of the new section.

Avoid immediately speaking faster. That usually creates a second problem: the delivery sounds rushed while the system is still trying to find a stable phrase. Pause, look at the next written line, and restart with its first distinctive words.

Troubleshooting by symptom

  • The text does not begin moving: confirm microphone permission, speak a complete written phrase, and verify that Voice Sync—not fixed-speed scrolling—is selected.
  • The text advances late: move the device or microphone closer, reduce competing speech, and simplify sentences with several repeated words.
  • The text jumps after improvisation: stop adding new material, pause, and re-enter at a unique phrase near the start of the next paragraph.
  • Your delivery becomes robotic: hide less text, shorten the sentences, and rehearse the meaning of the section before testing recognition again.
  • The first line is hardest to start: memorize only the opening sentence, begin with eye contact, then let the prompt support the rest.

If a room is too noisy or microphone access is unavailable, fixed-speed scrolling is the dependable fallback. The free online teleprompter lets you rehearse that workflow in the browser.

A practice script that tests real behavior

Paste this into a new script and replace the bracketed directions with your own cues:

[look at camera] Today I am testing a teleprompter that follows my voice.

[pause] I can slow down here, without chasing text that keeps moving.

I will add one short unscripted thought, then return to this exact phrase.

Now the important part: the script should support the message, not control the performance.

[smile] When the setup feels invisible, I am ready to record.

The bracketed cues are useful for rehearsal and can work with supported ScrollVox AI Skip behavior. Review every detected cue before recording so words intended for the audience are not treated as directions. The full cue workflow is covered in How to Format Teleprompter Cues.

Frequently asked questions

Do I need to read every word exactly?

No. Small wording changes and short additions are normal. For reliable recovery, keep the structure and return to a distinctive phrase that still exists in the script. If most paragraphs become improvised, use a shorter outline rather than pretending it is a word-for-word script.

Should I use Voice Sync for a strict 30-second ad?

Use it when natural delivery is more important than an exact runtime. For a segment that must hit a fixed duration, estimate the script first and compare both modes using the process in Voice-Controlled Teleprompter vs Auto-Scroll.

What should I rehearse before recording?

Rehearse the opening, every transition, difficult names or numbers, and the closing action. You do not need to memorize the whole script. You need to know where each section is going so a prompt never becomes the only source of meaning.

Can I use Voice Sync for YouTube tutorials?

Yes, especially when demonstrations and explanations create variable pauses. The YouTube teleprompter setup guide covers the surrounding camera, audio, lighting, and recording workflow.

Quick recording checklist

  • The script sounds natural when read aloud.
  • Microphone access is enabled.
  • Text is large enough to scan quickly.
  • The active line sits close to the camera lens.
  • You are speaking at your own pace.
  • Pauses are intentional, not rushed.
  • A short calibration take has been reviewed with sound.
  • You know the phrase you will use to restart each difficult section.

Voice Sync should feel less like operating a scrolling tool and more like having the script quietly keep up with you.
