TTS Use Best Tip Gap Control
August 12, 2025

Make Your Content More Natural and Faster with the “Gap Control” Feature

Hi there!

Today, I’m introducing the “Gap Control” feature in Supertone Play’s TTS tool.

If you’re an audiobook creator, YouTube Shorts editor, or short-form content maker,

this essential feature can make your workflow much faster.

🔧 What Is the Gap Control Feature?

Supertone Play’s Gap Control lets you adjust the word gaps and sentence gaps

in your TTS-generated audio to suit your style.

It appears only when you download TTS audio

and works differently depending on the save mode:

  • Single-line save

    👉 Adjust word gaps only
  • Multi-line save as one file

    👉 Adjust word gaps + sentence gaps

🗣️ Word Gaps – Control Your Speaking Tempo

By default, word gaps are set to 100%, meaning the original speaking speed.

How to use:

  • When you need a faster pace
  • Reduce to 80% or 60% for a tighter tempo.
  • For ultra-fast rap-style shorts
  • Set to 20–30% to make words almost merge, ideal for dense AI Shorts.

The top example is at 100%, the bottom at 20%.

See the speed difference?

This lets you create at the desired speed without extra audio editing.

🧘 Sentence Gaps – Clearer Audio Flow

Before, saving multiple lines in one file made audio flow

with no breathing space, making it hard to edit or follow.

Now, you can set your own breathing space between lines.

  • Gap range: 0.0s ~ 5.0s
  • Precise setting: decimal units supported (e.g., 1.2s, 2.4s)

Above) Default sentence spacing 0 seconds below) Adjust sentence spacing to 3 seconds

Looking at the image, you can see that in the upper audio,

it's difficult to tell where the next line begins,

but the lower image shows audio downloaded

with a 3-second interval between sentences.

With this 3-second spacing,

it becomes much clearer to identify where each line begins and ends.

📚 For audiobooks, explanatory content,

and other formats with multiple consecutive sentences,

setting appropriate spacing improves listening quality

and makes line-by-line editing much easier.

⏱️ For More Efficient TTS Production

Gap Control lets you reduce editing time, improve listening quality,

and boost your final output all at once.

It’s a must-have for TTS-based projects like audiobooks, ads, Shorts, and more.

Available in the Supertone Play Creator plan and above.

We’ll keep updating Supertone Play to enhance TTS features

and make AI voice production even more convenient.
