• Authors: Derek Tam, Surafel M. Lakew, Yogesh Virkar, Prashant Mathur, Marcello Federico
• Abstract summary: We introduce the task of prosody-aware machine translation which aims at generating translations suitable for dubbing. Dubbing of a spoken sentence requires transferring the content as well as the prosodic structure of the source into the target language to preserve timing information. We propose an implicit and explicit modeling approaches to integrate prosody information into neural machine translation.

• Abstract: We introduce the task of prosody-aware machine translation which aims at generating translations suitable for dubbing. Dubbing of a spoken sentence requires transferring the content as well as the prosodic structure of the source into the target language to preserve timing information. Practically, this implies correctly projecting pauses from the source to the target and ensuring that target speech segments have roughly the same duration of the corresponding source segments. In this work, we propose an implicit and explicit modeling approaches to integrate prosody information into neural machine translation. Experiments on English-German/French with automatic metrics show that the simplest of the considered approaches works best. Results are confirmed by human evaluations of translations and dubbed videos.

  We introduce a novel model framework TransVIP that leverages diverse datasets in a cascade fashion. We propose two separated encoders to preserve the speaker's voice characteristics and isochrony from the source speech during the translation process. Our experiments on the French-English language pair demonstrate that our model outperforms the current state-of-the-art speech-to-speech translation model.

  Video dubbing aims to translate the original speech in a film or television program into the speech in a target language. To ensure the translated speech to be well aligned with the corresponding video, the length/duration of the translated speech should be as close as possible to that of the original speech. We propose a machine translation system tailored for the task of video dubbing, which directly considers the speech duration of each token in translation.

  First sentences and titles of linked Wikipedia pages, as well as cross-lingual image captions, are strong signals for a seed parallel data to extract bilingual dictionaries and cross-lingual word embeddings for mining parallel text from Wikipedia. In image captioning, we train a multi-tasking machine translation and image captioning pipeline for Arabic and English from which the Arabic training data is a wikily translation of the English captioning data. Our captioning results in Arabic are slightly better than that of its supervised model.

  End-to-end speech translation aims to translate speech in one language into text in another language via an end-to-end way. Most existing methods employ an encoder-decoder structure with a single encoder to learn acoustic representation and semantic information simultaneously. We propose a Speech-to-Text Adaptation for Speech Translation model which aims to improve the end-to-end model performance by bridging the modality gap between speech and text.
