Europarl-ST: A Multilingual corpus for Speech Translation of Parliamentary Debates
Table 4: ASR results in terms of WER on the test sets.
['[EMPTY]', 'De', 'En', 'Es', 'Fr']
, WER figures computed from the ASR part only. Rows represent source (ASR) languages, whilst columns represent target (MT) languages. It is important to remind that the set of source speeches, though mostly overlapping, are different because the correspoding target text translation may not exist. Results show that most WER figures are below 20%, except in those pairs having French as input language. This is explained because the French ASR system does not feature BLSTM acoustic models, and it is the language with least acoustic resources.
