How to Transcribe YouTube Videos: Tools & Process Explained

For those of you, this article explains how to transcribe videos uploaded to YouTube.

Transcribing the audio from YouTube videos can be incredibly useful.

Especially for video creators (YouTubers), transcribing your videos and adding subtitles can help you reach a wider audience.

When transcribing, using an AI transcription service is highly recommended.

Transcribing videos uploaded to YouTube also helps with monetization.

Why not use this article as a guide to add subtitles to your videos?

What are the benefits of transcribing YouTube videos?

First, let's explain why you should transcribe YouTube videos.

Transcribing YouTube videos allows you to add "subtitles"

The main reason to transcribe YouTube videos is to add subtitles to them.

You've probably seen subtitles when watching YouTube videos.

This article will explain how to add these subtitles.

Subtitles boost viewership

The biggest reason to add subtitles to YouTube videos is that it increases viewership.

With subtitles, more people can conveniently watch your videos, leading to an increase in views.

What's also very important is that videos with subtitles can be watched by international viewers who can translate the subtitles.

YouTube has an automatic translation feature for subtitles.

(It's located next to the playback speed menu)

This automatic translation feature cannot be used if subtitles are not set for the video.

For example, videos uploaded before the subtitle feature existed cannot use the translation function because they lack subtitle settings.

By adding subtitles to your YouTube videos, you can target a global audience and significantly increase your viewership.

AI transcription services are better than auto-generated subtitles

This article will introduce two methods:

• YouTube's auto-generated subtitles
• AI transcription services

However, if you're adding subtitles to videos uploaded to YouTube, it's better to use an external AI transcription service to create your own subtitles rather than relying on auto-generated ones.

The reason is that YouTube's auto-generated subtitles often contain transcription errors.

If you've ever displayed subtitles while watching YouTube, you've likely seen incorrect captions appear.

While Google, which operates YouTube, possesses advanced technology, the speech recognition for YouTube's auto-generated subtitles seems to be slightly less accurate than the AI used by specialized transcription services.

To avoid misinterpretations and speech recognition errors, it's recommended to use the AI transcription services introduced in this article to set your own subtitles.

How to Automatically Generate Subtitles on YouTube

You can set the video's language in the video details screen.

Under "Language and caption certification", set "Video language" to Japanese.

[Recommended] Default upload settings

This language setting can be automatically applied when you upload videos by going to "Settings" in the bottom left of your YouTube channel management screen, then "Upload defaults" → "Advanced settings".

Setting "Video language" and "Title and description language" to Japanese is recommended to prevent forgetting to set them.
