Dataset Card for CrowdSpeech

Dataset Summary

CrowdSpeech is the first publicly available large-scale dataset of crowdsourced audio transcriptions. The dataset was constructed by annotation LibriSpeech on Toloka crowdsourcing platform. CrowdSpeech consists of 22K instances having around 155K annotations obtained from crowd workers.

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 is a corpus of approximately 1000 hours of 16kHz read English speech.

Annotations

Annotation was done on Toloka crowdsourcing platform 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.
