The data is organized in 3 main directories: "train" (training data), "dev" (validation data) and "test" (evaluation data). Each directory contains the subdirectories "original_audio" and "text", the first one containing speech data with annotations (for acoustic modelling), the second one containing text data (for language modelling).
Here we can see more completely the corpus structure, with additional subdirectories:
Europarl-ASR

│ │ │ ├── lists

└── raw
In the cases of "dev" and "test", they are subdivided in directories "spk-dep" and "spk-indep". Thus, for speech data, we have 2 train-dev-test partitions for 2 different ASR tasks, as follows:
ASR with known speakers (MEP):
train ; dev/original_audio/spk-dep ; test/original_audio/spk-dep
ASR with unknown speakers (Guest):
train ; dev/original_audio/spk-indep ; test/original_audio/spk-indep
Each of these partition directories contains 3 to 4 subdirectories (depending on whether it is the train set or the dev/test sets): "lists", "metadata", "refs" (only in "dev" and "test") and "speeches".
"lists" contains lists of all the speeches in "speeches", as well as lists of speeches per speaker.
"metadata" contains metadata for each speech and for each speaker in the corresponding set (as csv and json files). For each speech we will find these metadata (as reflected in speeches.headers.csv):
term;session_date;speech_id;speaker_type;speaker_id;raw_dur;
aligned-speech_dur;filtered-speech_dur;cer;ar;path;agenda_item_title
And for each speaker (as reflected in speakers.headers.csv):
type;id;name;gender;url
"speeches" contains a subdirectory for each speech in the corresponding set, according to this subdirectory structure:
speeches/<term>/<session_date>/<speech_id>/
For each speech, we will find some of the following files (depending on whether it is in the train set or in the dev/test sets):
ep-asr.en.orig.<term>.<session_date>.<speech_id>.m4a
[In all sets] Audio of the speech.
ep-asr.en.orig.<term>.<session_date>.<speech_id>.tr.orig.{dfxp,json,srt,txt}
[In all sets] 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.
ep-asr.en.orig.<term>.<session_date>.<speech_id>.tr.filt.{dfxp,json,srt}
[In train set] Automatically filtered transcription of the speech, as dfxp
or srt force-aligned timed subtitle files, and its json metadata.
ep-asr.en.orig.<term>.<session_date>.<speech_id>.tr.verb.{dfxp,json,srt,txt}
[In train set] Automatically verbatimized transcription of the speech, as
a txt transcription file, as dfxp or srt timed subtitle files,
and its json metadata.
ep-asr.en.orig.<term>.<session_date>.<speech_id>.tr.rev.{dfxp,json,srt,txt}
[In dev/test sets] Manually revised verbatim transcription of the speech,
as a txt transcription file, as dfxp or srt timed subtitle
files, and its json metadata.
Finally, in "refs" (only in "dev" and "test") each file contains every speech
in the corresponding dev or test set, that is, the full reference for that
set. In each case, we will find 4 files, containing the official non-verbatim
reference (*.orig.*
) and the manually revised verbatim reference (*.rev.*
), as
transcriptions (*.ref
) and as segment time marked files (*.stm
). In all 4
cases, the text is presented preprocessed for evaluation (tokenized,
lowercased, punctuation removed...).
In the case of "train", they are subdivided in directories "external" and "internal". "internal" contains all the official non-verbatim transcriptions and translations in the train set, together with the selected non-overlapping Europarl v10 transcriptions and translations; "external" contains the files to make use of the external DCEP: Digital Corpus of the European Parliament.
Each "text" directory contains 2 subdirectories: "raw" (except in "train/external"), "prepro" (in all sets), or "scripts" (only in "train/external").
"raw" contains the raw text data for the corresponding set (*.txt.gz
), and
its metadata (*.csv
). In the cases of "dev" and "test", both the official
non-verbatim transcriptions (*.orig.*
) and the manually revised verbatim
transcriptions (*.rev.*
) are included.
"prepro" contains the text data for the corresponding set, preprocessed for training or evaluation (tokenized, lowercased, punctuation removed...). This data is released to facilitate the reproducibility of our experiments.
Finally, "scripts" (only in "train/text/external") contains the script
get_DCEP.sh, which can be used to download the DCEP corpus from its original
website and save it in compressed plain text (.txt.gz
).
Europarl-ASR (EN) is a large English-language speech and text corpus of parliamentary debates for (streaming) ASR benchmarking and speech data filtering/verbatimization, including 1300 hours of annotated English-language speeches from European Parliament sessions held in the period 1996-2020.
It was compiled and released by the Machine Learning and Language Processing (MLLP) research group of VRAIN Institut Valencià d'Investigació en Intel·ligència Artificial, Universitat Politècnica de València ( www.mllp.upv.es ).
Europarl-ASR (EN) includes:
This data comprises most of the European Parliament's English-language debate recordings, transcriptions and translations available from the Parliament's website from 1999 to 2020 (recordings being only available from 2008). This is complemented by including all English-language transcriptions and translations from the Europarl v10 text corpus for the period 1996-1999.
Additionally, to increase text data for language modelling up to 170M tokens, Europarl-ASR also includes tools to add all English-language text from the DCEP Digital Corpus of the European Parliament.
Detailed dates of the EP speech and text data gathered:
