  This paper introduces GigaST, a large-scale pseudo speech translation (ST)
corpus. We create the corpus by translating the text in GigaSpeech, an English
ASR corpus, into German and Chinese. The training set is translated by a strong
machine translation system and the test set is translated by human. ST models
trained with an addition of our corpus obtain new state-of-the-art results on
the MuST-C English-German benchmark test set. We provide a detailed description
of the translation process and verify its quality. We make the translated text
data public and hope to facilitate research in speech translation.
Additionally, we also release the training scripts on NeurST to make it easy to
replicate our systems. GigaST dataset is available at
https://st-benchmark.github.io/resources/GigaST.
