    What is YouTube's Subtitle Translation Feature? How Live Caption and Auto-Translate Work

    Before explaining Chrome's features, let's briefly explain YouTube's standard subtitle features.

    How to Use YouTube's Subtitle Feature

    YouTube has both a subtitle feature and a translation feature.

    The subtitle feature displays subtitles on videos.

    You can display them by clicking "Subtitles" in the bottom right corner of the video.

    YouTube Has Manual and Automatic Subtitles

    There are two types of subtitles on YouTube:

    • Subtitles manually set by the video creator
    • Subtitles automatically generated by AI recognizing speech

    Manual subtitles require a lot of effort to set up, so across YouTube, most videos use automatic subtitles generated by AI.

    How to Translate YouTube Subtitles to Japanese Using the Auto-Translate Feature

    On YouTube, you can automatically translate video subtitles into other languages.

    Both manual and automatic subtitles can be translated.

    Steps to Use YouTube's Auto-Translate

    With subtitles displayed, click on "Settings" (the gear icon) in the bottom right of the video.

    Click Settings (gear icon)

    From the menu that appears, click "Subtitles".

    Click Subtitles

    From the menu that appears after clicking "Subtitles", click "Auto-translate".

    Click Auto-translate

    From the menu that appears after clicking "Auto-translate", select the target language for translation.

    Select languageFor example, Japanese is selected.

    Select Japanese

    ※The target language for translation may automatically be set to the user's language.

    Now, YouTube subtitles have been automatically translated into Japanese.

    Automatically translated state

    Some YouTube Videos Don't Show Subtitles or Can't Be Translated

    However, many YouTube videos do not display automatic subtitles.

    For example, the video in this image, uploaded by YouTube's official channel, does not allow the use of subtitles.

    Video that cannot display automatic subtitles

    Since there are no original subtitles, automatic translation is also not possible.

    There are two main reasons why automatic subtitles may not be available:

    Reason 1: Video Creator Has Not Configured Subtitles

    For automatic subtitles to be generated on a YouTube video, the video creator must set:

    • Language used
    • Permission for automatic subtitles

    If these settings are not configured for a video, automatic subtitles will not be displayed.

    Reason 2: Older Videos Without Subtitle Settings

    Older videos uploaded before YouTube's automatic subtitle feature was implemented may not have the necessary subtitle settings configured.

    If the video creator configures the settings later, automatic subtitles can be displayed even for older videos.

    Google Chrome's Live Caption Feature is the Solution

    Videos without automatic subtitles cannot be translated, making it difficult to understand foreign language videos such as English.

    In such cases, using Google Chrome's Live Caption feature is highly recommended!

    Chrome recognizes the audio in the video, automatically generates subtitles, and translates them into Japanese in real-time.

    Moreover, this feature is a standard Chrome function, so no extension installation is required.

    A major advantage is that it can be used for videos without subtitles on YouTube, as well as on other video sites.
