The latest r20190227 release of the English Zamia-Speech models for Kaldi have been trained on two additional corpora:

     zamia_en       0:05:38
     voxforge_en   72:16:35
     cv_corpus_v1 247:32:39
     librispeech  427:13:56
NEW: ljspeech      20:34:33
NEW: m_ailabs_en   43:31:54

additionally 400 hours of noise-augmented audio derived from the above corpora were used (background noise and phone codecs).
