Sequence-to-Sequence Models Can Directly Translate Foreign Speech

['[EMPTY]', 'Fisher dev', 'Fisher dev2', 'Fisher test', 'Callhome devtest', 'Callhome evltest']
We construct a baseline cascade of a Spanish ASR seq2seq model whose output is passed into a Spanish to English NMT model. Performance on the Fisher task is significantly better than on Callhome since it contains more formal speech, consisting of conversations between strangers while Callhome conversations were often between family members.
