In the video editor, you can listen to subtitle Audio playback in real time. Before exporting and playing the entire SOP, you can Check intonation, speed, and Reading accuracy at the Subtitle or Step level.

When to use this

You want to confirm that technical terms are pronounced correctly before exporting
You want to know if long Subtitles have natural pauses in the Audio playback
After changing the Pronunciation Dictionary (Registered readings), you want to hear and Confirm the effect immediately
For multilingual Subtitles, you want to Check if the Audio playback after Translation is easy to understand

Prerequisites

The target Step has "Subtitle Audio" turned ON (Subtitles with it OFF are not eligible for listening)
Text is entered in the Subtitle you want to listen to (Hidden or blank Subtitles are not eligible)

You can Switch Subtitle Audio ON/OFF from the Audio and Subtitles Settings in the video editor.

Listen to one Subtitle only

Open the video editor and check the Subtitles arranged in the Timeline at the bottom
Click the [Preview] button (speaker icon) for the Subtitle you want to listen to
The video seeks to the beginning of the Subtitle, and the Audio playback starts in real time (the video syncs and moves along)
Click the same button again to Stop

Video and Audio synchronization

During Preview, the video's original Audio is automatically Muted, and only the Audio playback is heard
The video position and Audio playback are synchronized, and automatically Stop when the Subtitle interval passes
Cut intervals (intervals Excluded in editing) are compressed on the Audio side as well, just like in the final output
If you seek on the Timeline during Preview, the Preview automatically Stops

Tips for using effectively

Check technical terms Subtitle by Subtitle: You can pinpoint and listen to only the Subtitles you're concerned about multiple times
Combine with the Pronunciation Dictionary: If there's a word whose Reading you want to change, Register it in the Pronunciation Dictionary and Confirm the effect with Preview
Also for confirming after Translation: Even for translated Subtitles, you can Confirm the Audio playback in that Language on the spot
Caching works: Subtitles with identical content play immediately from the second time onward. The Cycle of fine-tuning → re-Preview moves quickly
Preview does not affect the SOP itself: Since it's Preview-only, the Confirmed Audio playback data is not Changed

When you cannot Preview or hear no sound

Check that Subtitle Audio is not OFF for the Affected steps (Audio and Subtitles Settings)
If the Subtitle has no Text entered, or is set to Hide, it is not eligible for Preview
Check that your browser audio is not Muted, and also check your PC's own volume Settings
The first playback requires User Operation (clicking). Auto-play may be blocked by browser restrictions
