Speech-to-speech translation (S2ST) consists on translating speech from one language to speech in another language. This can be done with a cascade of automatic speech recognition (ASR), text-to-text machine translation (MT), and text-to-speech (TTS) synthesis
sub-systems, which is text-centric. Recently, works on S2ST without relying on intermediate text representation is emerging.

CVSS is a massively multilingual-to-English speech to speech translation (S2ST) corpus, covering sentence-level parallel S2ST pairs from 21 languages into English. CVSS is derived from the Common Voice speech corpus and the CoVoST 2 speech-to-text translation (ST) corpus, by synthesizing the translation text from CoVoST 2 into speech using state-of-the-art TTS systems

Each episode directory contains word-level and segment-level information of the whole episode and also parallel samples extracted under segments_eng and segments_spa subdirectories. Each sample is stored as an WAV audio file, text file and a CSV file containing word timing information and word-level paralinguistic and prosodic features. This dataset contains short audio and text excerpts from the TV series "Heroes" (Copyright Universal Media Studios (2006-2007,2007-2008, 2008-2009)). It is compiled and used only for research purposes. Creation of this dataset is partially financed by the UPF DTIC-Maria de Maeztu Strategic Program. This dataset is created with automated tools. There might be errors due to the automated process. Description from: https://repositori.upf.edu/handle/10230/35572
LibriS2S is a Speech to Speech Translation (S2ST) dataset build further upon existing resources. The dataset provides English-German speech and text quadruplets ranging just over 50 hours for both languages.
