All the main application functions work well with any MP3 file, though subtitle files will make your life easier. The major advantage is that you would not need to switch to another application to see the text, if a fragment of your audio is not clear.

Let’s have a look at how the main window changes if a subtitle file is opened:

Main form

First, a subtitles area appears. Depending on whether "Show always" button is switched on or off the application behaves differently.

  • "Show always" is switched on:

    Subtitles are shown at all times corresponding to the selected sound fragment.
  • "Show always" is switched off:

    To see subtitles for the selected fragment press in the subtitles area. Subtitles will disappear when you move onto the next fragment. Also you can hide them by quickly pressing again in the subtitles area. I suggest you study in this mode as it trains your hearing better. See more on "Learning Methodology" page.

You can translate an unknown word in subtitles. First, select it by pressing on it for a few seconds. Then, press "Find in the Dictionary" button. Your dictionary app should be chosen at Settings screen.

Other buttons:

  • Select more, less, all text
  • Copy into Clipboard
  • On the phone: Switch to file information or notes or back to subtitles

Subtitle file can have a table of content. In this case "Go" button shows "Heading" item. Also notches appear on the progress bar, showing headings’ positions.

This application supports two formats of subtitles:

  • SRT (SubRip) format:

    The most common subtitle format for movies. Files should have "srt" extension.
  • WorkAudioBook HTML format:

    Subtitles format specially designed for this application. It is fully compatible with HTML format of web pages. Files should have "html", "htm" or "txt" extensions.

Secondary subtitles. Apart from the main subtitles, you can open additional ones. For example, if you learn Russian and you have a sound track of some Russian movie and subtitles in Russian and English, you can open English subtitles as primary, and Russian as secondary. In this case, if you doubt your translation of a Russian phrase, you can look into the version translated by the professional. To open secondary subtitles, press "Open" > "Secondary Subtitles File"

Use this button to switch between primary and secondary subtitles:

If subtitles file’s name matches with the name of the MP3 file, for example, there is a file named "SomeBook.html", "SomeBook.htm", "SomeBook.txt" or "SomeBook.srt" in the same folder with "SomeBook.mp3" file – then the application will open such files automatically together with opening the MP3 file. If the name of a subtitles file differs from the name of the MP3 file – you can open it separately with the help of "Open" button, after MP3 is opened. Please, pay attention, that the "SomeBook.html", "SomeBook.htm" or "SomeBook.txt" files should have a specific markup according to WorkAudioBook HTML format, not just to be an arbitrary text files.


Subtitles settings

  • Select phrases. You can change phrase searching algorithm:

    • Use "Exactly as subtitles" or "Use subtitles as hints" mode if subtitles file contains a high-quality correspondence between the timing of subtitles text and audio.
    • Use "Subtitles don't affect phrase selection" mode, if the correspondence is inaccurate.
  • How to select text. Select "By letters" if you learn Japanese or Chinese, where words aren't separated by spaces.

Secondary subtitles settings

  • Suffix. If you specify the correct suffix, the secondary subtitle files will be opened automatically. For example, if for file "01.mp3" you have secondary subtitle file "01.rus.srt", then specify ".rus" as suffix.

Where to get subtitled audio materials

There are several options:

  • If you are studying English, then you can download several audiobooks to which I and other users have created subtitles.
  • If you have movies with the audio tracks in the language you are studying, plus you have the SRT subtitles files – you can extract the audio tracks in MP3 files. See more on "Audio tracks from Movies" page.
  • From video on YouTube. See more on "Audio tracks from YouTube" page.
  • And last, but not the least, if you have the text of an audiobook, then you can:
    • Create subtitles in Subtitles Editor in Windows version (the fastest variant!)
    • Copy text into notes for file
    • Create subtitles based on "notes for file" with the help of bookmarks (in Android version)
    Then, you can share the results of your work with other people and make the world better! :)
