By "convert audio to text", I assume that the audio is of spoken words 
in a human spoken language, rather than music or white noise. Another 
term for that operation is "speech recognition".

I have never tried to perform speech recognition with FFmpeg. However, I 
do see documentation for an "asr" filter:


"Automatic Speech Recognition. This filter uses PocketSphinx for speech 
recognition. To enable compilation of this filter, you need to configure 
FFmpeg with |--enable-pocketsphinx|."

Perhaps this will help you make progress figuring out a command line.
