Dataset Card for sberdevices_golos_100h_farfield

Dataset Summary

Sberdevices Golos is a corpus of approximately 1200 hours of 16kHz Russian speech from crowd (reading speech) and farfield (communication with smart devices) domains, prepared by SberDevices Team (Alexander Denisenko, Angelina Kovalenko, Fedor Minkin, and Nikolay Karpov). The data is derived from the crowd-sourcing platform, and has been manually annotated. Authors divide all dataset into train and test subsets. The training subset includes approximately 1000 hours. For experiments with a limited number of records, authors identified training subsets of shorter length: 100 hours, 10 hours, 1 hour, 10 minutes. This dataset is a simpler version of the above mentioned Golos:

• it includes the farfield domain only (without any sound from the crowd domain);
• validation split is built on the 10-hour training subset;
• training split corresponds to the 100-hour training subset without sounds from the 10-hour training subset;
• test split is a full original test split.

Supported Tasks and Leaderboards

• automatic-speech-recognition: The dataset can be used to train a model for Automatic Speech Recognition (ASR). The model is presented with an audio file and asked to transcribe the audio file to written text. The most common evaluation metric is the word error rate (WER). The task has an active Hugging Face leaderboard which can be found at https://huggingface.co/spaces/huggingface/hf-speech-bench. The leaderboard ranks models uploaded to the Hub based on their WER.

Languages

The audio is in Russian.

Dataset Structure

Data Instances

A typical data point comprises the audio data, usually called audio and its transcription, called transcription. Any additional information about the speaker and the passage which contains the transcription is not provided.

{'audio': {'path': None,
  'array': array([ 1.22070312e-04,  1.22070312e-04,  9.15527344e-05, ...,

  'sampling_rate': 16000},
 'transcription': 'джой источники истории турции'}

Data Fields

• audio: A dictionary containing the path to the downloaded audio file, the decoded audio array, and the sampling rate. Note that when accessing the audio column: dataset[0]["audio"] the audio file is automatically decoded and resampled to dataset.features["audio"].sampling_rate. Decoding and resampling of a large number of audio files might take a significant amount of time. Thus it is important to first query the sample index before the "audio" column, i.e. dataset[0]["audio"] should always be preferred over dataset["audio"][0].
• transcription: the transcription of the audio file.

Data Splits

This dataset is a simpler version of the original Golos:

• it includes the farfield domain only (without any sound from the crowd domain);
• validation split is built on the 10-hour training subset;
• training split corresponds to the 100-hour training subset without sounds from the 10-hour training subset;
• test split is a full original test split. | | Train | Validation | Test |
