Empty strings in transcription results

[dimqua]

Hello. Each time when I transcribe English-language films I get lots of empty strings in the resulted subtitles. Basically more than half of all dialogues aren't fully transcribed. I use the following command: autosub -S en-us -of all -i movie.mkv The json file contains lots of emptiness as well:

    {
        "start": 72.58,
        "end": 82.57,
        "content": ""
    },
    {
        "start": 82.58,
        "end": 92.57,
        "content": ""
    }

I wonder why it may happen, and whether or not I can do something about it? With movies in other languages, I don't have such a problem.
