Download Pretrained Models

# Usage: mfa model download [OPTIONS] [TYPE] [MODEL_NAME]
mfa model download --ignore_cache acoustic dutch_cv

Train G2P Model

# Usage: mfa train_g2p [OPTIONS] DICTIONARY_PATH OUTPUT_MODEL_PATH
mfa train_g2p --clean -j 16 dutch_cv ~/Documents/MFA/btamm/g2p/dutch_cv.zip
# mfa train_g2p --clean --phonetisaurus -j 16 dutch_cv ~/Documents/MFA/btamm/g2p/dutch_cv_phonetisaurus.zip --alignment_separator "°"

The arg --alignment_separator "°" avoids the following error, I haven't tested if it works properly though...

The symbol ";" is reserved for "alignment_separator", but is found in the graphemes or phonemes of your dictionary.
Please re-run and specify another symbol that is not used in your dictionary with the "--alignment_separator" flag.
