I am looking for simple converter from mp3 to txt. I have tried, without success: julius, CMU Sphinx, ... In the past 4 hours I did not find a way how to use them (or properly install them).
What I am looking for is something like:
$ converterapp -infile myspeech.mp3 -outfile myspeech.txt
I am also fine with GUI application since I only have a few files to convert and can click around.
Edit: With the help of this answer Speech-recognition app to convert MP3 to text? I manged to get it working but it produces no output. Well, actually it produces a couple of blank lines (no words detected)...
