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.	Language: English The dataset is split into 3 sections with 100.6, 363.6, 496.7 hours of speech. The gender ratio of speakers is about half and half.	Dataset is made by Vassil Panayotov. Guoguo Chen, Daniel Povey, Sanjeev Khudanpur also contributed to the dataset and article below.	Alice Vanni Lifan Qu Ting Zhang Yilan Wei Siqi Zheng
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.	Prepared by Vassil Panayotov with the assistance of Daniel Povey	Yuxing Ouyang Xiaoling Lin Xueying Liu Jingxuan Yue M.Tepei The Part 2 of group work is on Librispeech.
LibriVoxDeEn	Audio based on audio books (.wav file format) German text and English translation (.tsv file format)	Low Disfluencies: The speech data in the dataset have a low level of disfluencies. Quality Evaluation: The quality of both audio and sentence alignments in the dataset has been assessed through manual evaluation. Sentence Alignment Quality: The quality of sentence alignments is stated to be comparable to widely-used parallel translation datasets.	Creative Commons Attribution 4.0 Non-Commercial ShareAlike Internation License	German audio and transcription, with English translation. >100 hours of audio material and >50k parallel sentences. Quality of audio and text has been evaluated manually.	Benjamin Beilharz, Xin Sun, Sariya Karimova, Stefan Riezler	Jocomin Galarneau & Ding Shenghuan & Ömer Tarik Özyilmaz
SPEECH-COCO	wav: spoken caption json: metadata of WAV file sqlite3: SQLite databases containing all the information contained in the JSON files	Using SOX tempo command, change the speed without changing the pitch to make the captions sound more natural. 1/3 of the captions are 10% slower than the original pace, 1/3 are 10% faster. Modify approximately 30% of the original captions and add disfluencies such as "um", "uh", "er" to make the captions more natural.	Creative Commons Attribution 4.0 International Liscence	Language: English This corpus contains 616,767 spoken captions from MSCOCO's val2014 and train2014 subsets 8 different voices. 4 of them have a British accent and the 4 others with American accent.

Europarl-ASR	Based on English-language annotated speech, with json metadata, txt, dfxp, srt	Official non-verbatim transcription of the speech, as a txt raw transcription file, as dfxp or srt force-aligned timed subtitle files, and its json metadata. Automatically filtered transcription of the speech, as dfxp or srt force-aligned timed subtitle files, and its json metadata. Automatically verbatimized transcription of the speech, as a txt transcription file, as dfxp or srt timed subtitle files, and its json metadata. Manually revised verbatim transcription of the speech, as a txt transcription file, as dfxp or srt timed subtitle files, and its json metadata. In each case, we will find 4 files, containing the official non-verbatim reference and the manually revised verbatim reference , as transcriptions and as segment time marked files. In all 4 cases, the text is presented preprocessed for evaluation (tokenized, lowercased, punctuation removed...).	Creative Commons Public Licenses CC BY 4.0 License	1300 hours of English-language annotated speech data. 3 full sets of timed transcriptions: official non-verbatim transcriptions, automatically noise-filtered transcriptions and automatically verbatimized transcriptions. 18 hours of speech data with both manually revised verbatim transcriptions and official non-verbatim transcriptions, split in 2 independent validation-evaluation partitions for 2 realistic ASR tasks (with vs. without previous knowledge of the speaker). 70 million tokens of English-language text data and Europarl-ASR English-language n-gram language model and vocabulary.

TED-LIUM 3	TED-LIUM 3 is an audio dataset collected from TED Talks: 2351 audio talks in NIST sphere format (SPH) and their aligned automatic transcripts in STM format TEDLIUM 2 dev and test data: 19 TED talks in SPH format with corresponding manual transcriptions Dictionary with pronunciations (159848 entries) Selected monolingual data for language modeling from WMT12 publicly available corpora	Accurate alignments between the speech and transcribed text were achieved using an in-house tool called LIUM_SpkDiarization, designed for speaker segmentation and clustering. Speech disfluencies like repetitions, hesitations, and false starts were handled as follows: repetitions were transcribed, hesitations were linked to specific filler words, and false starts were not accounted for.
