Please see
https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#fine-tuning-for-impact

The following command extracts the .lstm file from the .traineddata file.

training/combine_tessdata -e tessdata/best/eng.traineddata \
  ~/tesstutorial/impact_from_full/eng.lstm

lstm file is the language model. It is saved in traineddata file.

dawgs are a kind of compressed files, created from lists of words,
punctuation or numbers.

You can use dawg2wordlist to unpack them.

Please follow the instructions on the training wiki page.
