If your level is good enough you can download classical audiobooks from LibriVox: https://librivox.org/
Also you can use audio tracks from movies: http://www.workaudiobook.com/WorkAudioB ... ag=windows
But WorkAudioBook isn't good enough in splitting audio, if there are a lot background noise.
But if you also have good subtitles in SRT format for this movie this will help you.
With subtitles you can select in Settings > Subtitles > Select phrases: "Exactly as subtitles" option.
Also you can extract audio tracks and subtitles from YouTube videos: http://www.workaudiobook.com/WorkAudioB ... ag=windows
