**Data Fields:**
- `audio`: The speech audio file in the Tatar language
- `text`: The transcription of the audio file in Tatar
- `duration`: Length of the audio in seconds
- `file_id`: Unique identifier for the audio file
- `speaker_id`: Identifier for the speaker in the recording

## Data Processing

Information about text normalization or preprocessing is not explicitly provided in the source.

**Audio Processing:**  
The audio samples range from very short utterances (0.21s) to longer segments (31.1s).
