Additional reference translations were collected for 3 out of the 14 language directions covered by MuST-C, i.e. English-German/Italian/Spanish, and consist of professional post-edits of the output of two state-of-the-art systems that represent the main current ST approaches, namely a cascade ASR+MT system and a direct ST system.
For each language direction, the PE-SET includes 550 segments, corresponding to around 10,000 English source words.
For each segment we release the audio file, the manual reference transcription and translation from MuST-C, the outputs of the cascade and direct ST systems, the post-edits of the two systems.
The segments are largely overlapping across the three covered language directions to allow cross-lingual comparative evaluation.
