I want to run Deepspeech (native_client/java) on my mobile phone using Android Studio (Win 7 64)

Set --n_hidden to 800?
The remaining parameters are correct?

python3 DeepSpeech.py --n_hidden 800 --checkpoint_dir path / to / checkpoint / folder --epochs 3 --train_files my-train.csv --dev_files my-dev.csv --test_files my_dev.csv --learning_rate 0.0001

On which computer and how long can such training take? About. If you use Common Voice data for the English language.
Can be specified in dozens of hours.

Thank.
