 ### Dataset Summary
 
-CrowdSpeech is the first publicly available large-scale dataset of crowdsourced audio transcriptions.
+CrowdSpeech is the first publicly available large-scale dataset of crowdsourced audio transcriptions.
+The dataset was constructed by annotation [LibriSpeech](https://www.openslr.org/12) on [Toloka crowdsourcing platform](https://toloka.ai).
+CrowdSpeech consists of 22K instances having around 155K annotations obtained from crowd workers.
+
+
+### Supported Tasks and Leaderboards
+Aggregation of crowd transcriptions.
+
+### Languages
+English
+
+## Dataset Structure
+
+### Data Instances
+
+A data instance contains a url to the audio recording, a list of transcriptions along with the corresponding performers identifiers and ground truth.
+For each data instance, seven crowdsourced transcriptions are provided.

+
+### Data Fields
+
+* task: a string containing a url of the audio recording
+* transcriptions: a list of the crowdsourced transcriptions separated by '|'
+* performers: the corresponding performers' identifiers.
+* gt: ground truth transcription
+
+### Data Splits
+
+There are five splits in the data: train, test, test.other, dev.clean and dev.other.
+Splits train, test and dev.clean correspond to *clean* part of LibriSpeech that contains audio recordings of higher quality with accents 
+of the speaker being closer to the US English. Splits dev.other and test.other correspond to *other* part of LibriSpeech with 
+the recordings more challenging for recognition. The audio recordings are gender-balanced.
+
+## Dataset Creation
+
+### Source Data
+
+[LibriSpeech](https://www.openslr.org/12) is a corpus of approximately 1000 hours of 16kHz read English speech.
+
+### Annotations
+
+Annotation was done on [Toloka crowdsourcing platform](https://toloka.ai) with overlap of 7 (that is, each task was performed by 7 annotators).
+
+Only annotators who self-reported the knowledge of English had access to the annotation task.
+Additionally, annotators had to pass *Entrance Exam*. For this, we ask all incoming eligible workers to annotate ten audio
+recordings. We then compute our target metric — Word Error Rate (WER) — on these recordings and accept to the main task all workers 
+who achieve WER of 40% or less (the smaller the value of the metric, the higher the quality of annotation).
+
+The Toloka crowdsourcing platform associates workers with unique identifiers and returns these identifiers to the requester. 
+To further protect the data, we additionally encode each identifier with an integer that is eventually reported in our released datasets.
+
