This dataset is a machine-learning-ready subset of the INEL Kalmyk Corpus (Version 1.0), processed specifically for Automatic Speech Recognition (ASR) / Speech-to-Text (STT) training. It translates the detailed EXMARaLDA XML annotations into the standard tabular layout utilized by Mozilla Common Voice. The dataset comprises 3 hours and 15 minutes of aligned supervised speech data (1,934 individual clips) across 26 speakers. It strictly populates the primary 'sentence' column using the 'ts' tier (scientific transcription) to ensure phonetic accuracy, with demographic metadata included where available.

This dataset is a machine-learning-ready subset of the INEL Kalmyk Corpus (Version 1.0), processed specifically for Automatic Speech Recognition (ASR) / Speech-to-Text (STT) training.
Kalmyk (ISO 639-3: xal) is a Mongolic language spoken primarily by the Kalmyk people in the Republic of Kalmykia (Russian Federation). The recordings in this corpus were collected between 2007 and 2018 in the Ketchenerovsky District and predominantly feature the Derbet and Torgut dialects.
Language: Kalmyk (xal)
Total Speakers: 26
Total Audio Clips: 1934 sentences
Total Audio Duration: 03:15:58 (HH:MM:SS)
Audio Format: MP3
The dataset provides audio clips aligned at the sentence level alongside a train.tsv metadata file.
The train.tsv contains the following Common Voice conforming fields:
client_id: Unique speaker abbreviation.
path: The filename of the corresponding audio clip.
sentence: The primary transcribed text of the audio.
age: The calculated age of the speaker at the time of recording.
gender: male or female.
accents: Specific dialect information (e.g., Derbet or Torgut dialect).
locale: Locale code (xal).
The original INEL Kalmyk corpus does not provide transcriptions in Kalmyk Cyrillic. To ensure the highest phonetic accuracy for training, this dataset strictly populates the primary sentence column using the ts tier (scientific transcription) from the original EXMARaLDA files.
Future Release Note: We plan to update the sentence column in future releases to use the official Kalmyk Cyrillic orthography. When this update occurs, the original INEL scientific transcriptions will remain fully preserved in the ts column.
The raw INEL tier is also preserved in the TSV for reference:
ts: Scientific/phonological transcription (exact source for the current sentence column).
Note: To maintain a streamlined, single-task focus on Speech-to-Text modeling, extensive linguistic annotations such as morphological glossing and secondary translations (English, Russian) have been excluded from this specific audio dataset. A separate parallel-text dataset may be released in the future.
The following represents all unique characters encountered in the sentence column of this dataset. They are sorted by uppercase, then lowercase, and finally all other symbols:
