The dataset is organized into the following directories and files:

audio/

other/: Contains .tar archives like uz_other_0.taruz_other_1.tar
train/: Contains .tar archives like uz_train_0.tar.
validated/: Contains .tar archives like uz_validated_0.tar, uz_validated_1.tar, and uz_validated_2.tar.
test/: Contains individual .wav files.
transcription/: Contains .tsv files including:

other.tsv
train.tsv
validated.tsv
test.tsv
The .tsv files have two columns: file_name and transcription. Each entry provides the path to the audio file and its corresponding transcription.

Data Instances
A typical data point includes:

Audio File: Path to the .wav and mp3 files.
Transcription: Text transcribed from the audio.
Example data instance:


{
  "file_name": "audio/train/common_voice_uz_28907218.mp3",
  "transcription": "Bugun ertalab Gyotenikiga taklifnoma oldim."
}

Data Preprocessing Recommended by Hugging Face
The following are data preprocessing steps advised by the Hugging Face team. They are accompanied by an example code snippet that shows how to put them to practice.

Many examples in this dataset have trailing quotations marks, e.g "Musibat yomonlarning zulmida emas, yaxshilarning jim turishida.". These trailing quotation marks do not change the actual meaning of the sentence, and it is near impossible to infer whether a sentence is a quotation or not a quotation from audio data alone. In these cases, it is advised to strip the quotation marks, leaving: the cat sat on the mat.

In addition, the majority of training sentences end in punctuation ( . or ? or ! ), whereas just a small proportion do not. In the dev set, almost all sentences end in punctuation. Thus, it is recommended to append a full-stop ( . ) to the end of the small number of training examples that do not end in punctuation.
