Short-form optimization voice that doubles viewing duration
July 2, 2025

Hello! I'm Olive, the Supertone Voice Creator 💓

My hard-working shorts and reels, how do I get them to see the end?

The key to reducing drop-off rates is in the 'voice'!

We are now in the era of short-form content.

YouTube Shorts and Instagram Reels are focusing more on short-form.

However, even the best short-form content is useless if viewers drop off early.

What causes drop-offs, and what encourages viewers to watch till the end?

'Voice' could be the answer.

📉 The hidden cause of drop-offs: boring and flat voices

No matter how visually appealing your video is,

emotionless voices or mechanical speech patterns disrupt viewer immersion.

When monotonous tones or unnatural TTS voices are repeated,

viewers easily experience auditory fatigue,

which is why voice tone variation and matching the content's tone are important!

Creating short-form immersion through 'tone design'

A voice that matches the mood of your content delivers messages

more effectively and increases audience focus.

It's an essential element of getting the 'tone and manner' right.

Check out the recommended voice tones for your content type.

  • Informational Short-form : Clear and distinct delivery, trustworthy tone
  • Emotional Vlog : Soft and warm tone, emotionally-paced delivery
  • Challenge·Entertainment : Bright and dynamic tone, rhythmic speech pattern

Once you've found the right voice,

making viewers stop scrolling is all about 'the first words'

In content like Shorts where the battle is decided in seconds,

there's only one thing that stops a viewer's finger: 'the first words'.

In feeds flooded with countless videos,

users listen to the sound and make judgments before even looking at the screen.

If there's a 'Hook' that stimulates curiosity and touches emotions,

rather than a simple greeting or background explanation,

it can capture that brief moment and lead to longer, deeper immersion.

Completion rate is the key to the algorithm

Platform algorithms don't simply look at view counts.

What really matters is view retention, or 'completion rate'.

💡 When completion rates increase:

  • Platforms will prioritize your content in recommendations.
  • Likes, saves, and follows naturally increase.
  • Branding/marketing effects are maximized.

In other words, a 'voice that makes viewers watch to the end' is

a key weapon that creates results beyond just view counts.

Designing short-form content that captures attention with voice

is no longer optional, but essential.

In short-form videos, strategies to capture viewers' 'eyes' are basic,

but you must also design strategies to grab their 'ears' to enhance content quality.

The voice you choose isn't just a simple sound,

but a power that makes viewers watch to the end and a key element that moves the algorithm.

Use the perfect voice for your short-form content

from over 200 diverse voices offered by Supertone Play.

You can express tones suitable for various content types

and vivid emotional styles appropriate for different situations.
