Dictionary - How to select thousands of words from WAV file and save each into single files?

Hello, Could someone help me please?
I got an WAV audio file with 5000 single words in english read one by another with 1s space between - for a dictionary needs. And i got the same in polish.

I got 2 questions?

  1. how can i automated check in Audacity to select all the phrases/words and save it into 5000 single words.
  2. how can i join then 5000 words eng + 5000 words pl - into one file (1 eng word + 1 pl word) ?

Is there a functionality here?

Thank you.

There is a Silence Finder effect that would create labels for you, and there is probably a macro that would export audio files by label.
