Dataset Summary

SOVA Dataset is free public STT/ASR dataset. It consists of several parts, one of them is SOVA RuDevices. This part is an acoustic corpus of approximately 100 hours of 16kHz Russian live speech with manual annotating, prepared by SOVA.ai team.

Authors do not divide the dataset into train, validation and test subsets. Therefore, I was compelled to prepare this splitting. The training subset includes more than 82 hours, the validation subset includes approximately 6 hours, and the test subset includes approximately 6 hours too.

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': '/home/bond005/datasets/sova_rudevices/data/train/00003ec0-1257-42d1-b475-db1cd548092e.wav',
  'array': array([  0.00787354,  0.00735474,  0.00714111, ...,
                   -0.00018311, -0.00015259, -0.00018311]), dtype=float32),
  'sampling_rate': 16000},
 'transcription': 'мне получше стало'}

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 consists of three splits: training, validation, and test. This splitting was realized with accounting of internal structure of SOVA RuDevices (the validation split is based on the subdirectory 0, and the test split is based on the subdirectory 1 of the original dataset), but audio recordings of the same speakers can be in different splits at the same time (the opposite is not guaranteed).
