replace google speech recognition with pocketsphinx (cmusphinx)

[r0ller]

Currently found no hungarian language model for pocketsphinx but found a hint according to which one can create a phonetic dictionary from a word list by espeak as a basis for training pocketsphinx:

cat word.list | espeak -v hu -x --sep=" " > phonetic.dictionary

Then train a language model with that dictionary using g2p-seq2seq.
