MuST-SHE is a multilingual benchmark allowing for a fine-grained analysis of gender bias in Machine Translation and Speech Translation.

MuST-SHE is a subset of the TED-based MuST-C corpus and is available for English-French, English-Italian and English-Spanish. The dataset is composed of (audio, transcript, translation) triplets annotated with qualitatively differentiated and balanced gender-related phenomena. Each triplet requires the translation of at least one English gender-neutral word into the corresponding masculine/feminine target word(s). MuST-SHE comprises 3,367 triplets (1,164 for En-Es, 1,108 for En-Fr, and 1,095 for En-It) uttered by 295 different speakers. Also, a common subset of 1,040 instances allows for comparative evaluations of gender translation across the three language directions.
