Dataset name	Type of data	Annotation remarks	License	Metadata	Name/s of people who are entering the data	Who are you entering the data?
LibriSpeech	Audio books (clean, flac format)	Text is converted into upper-case, removed punctuation, expanding common abbreviations and non-standard words. The transcriptions are aligned and segmented automatically.	Creative Commons Attribution 4.0 International License.

LibriSpeech	LibriSpeech is a corpus of approximately 1000 hours of read English speech with sampling rate of 16 kHz. The data is derived from read audiobooks from the LibriVox project, and has been carefully segmented and aligned.	Each book’s text is normalized by converting it into upper-case, re- moving the punctuation, and expanding common abbreviations and non-standard words.	CC BY 4.0	The audio recordings and transcriptions are all English The dataset is divided into different portions such as "train", "dev", and "test" to facilitate both training and evaluation The dataset is segmented into various sizes, denoted as "100" for 100 hours of audio, "360", and "500". The dataset is categorized into "clean" and "other" sets. The "clean" sets have high-quality recordings, while the "other" sets have recordings that might have more background noise or less clear pronunciations.

The LIUM team released two versions (respectively 118 hours of audio and 207 hours of audio) from the TED conference videos. Ubiqus joined these efforts to pursue the improvements both from an increased data standpoint, as well as from a technical achievement one.	Annie Zhou, XInyi Ma, Jingsi Huang, Igor, Wansu Zhu
