Kalmyk Speech to Text: Preserving a Minority Language with AI

Kalmyk (Хальмг келн) is a Mongolic language spoken primarily in the Republic of Kalmykia, a federal subject of Russia located on the steppes northwest of the Caspian Sea. It is the only Mongolic language spoken in Europe and belongs to the Oirat subgroup. With an estimated 80,000 native speakers, Kalmyk is classified as endangered by UNESCO. The language uses a Cyrillic script with additional letters, including Әә, Җҗ, Ңң, Өө, and Үү, to represent sounds specific to Kalmyk phonology.

Why Accurate Speech to Text Matters for Kalmyk

Accurate speech-to-text technology can help preserve and revitalize Kalmyk. Many native speakers are elderly, and younger generations often prefer Russian. Transcription makes oral literature, folk songs, and everyday conversations accessible in written form. It also supports language learning, media production, and academic research. Without reliable automatic transcription, documenting the language remains slow and labor-intensive.

Challenges in Transcribing Kalmyk Audio

Kalmyk presents several challenges for automatic speech recognition:

• Vowel harmony and long vowels: The language distinguishes front and back vowels, rounded and unrounded, and vowel length. These features are phonemic and must be captured correctly.
• Unique Cyrillic characters: The alphabet includes letters not found in Russian. Generic ASR systems often map these incorrectly or omit them.
• Dialectal variation: Torgut, Derbet, and Buzava dialects differ in pronunciation and vocabulary. A model trained only on standard Derbet may fail on other dialects.
• Limited training data: As a minority language, Kalmyk has far fewer publicly available speech datasets than major languages.

Speechyou addresses these challenges with a dedicated Kalmyk language model trained on diverse dialectal data and optimized for the Cyrillic script. The system uses transfer learning to achieve high accuracy despite data scarcity.

Use Cases for Kalmyk Transcription

Oral History and Folklore Preservation

Kalmyk has a rich oral tradition, including the epic Jangar, which consists of thousands of verses. Transcribing recordings of elders reciting these epics creates a searchable digital archive. Researchers can analyze linguistic features, compare versions, and share content with a global audience.

Education and Language Revitalization

Schools in Kalmykia use Kalmyk as a medium of instruction. Teachers can transcribe classroom discussions and create subtitled videos for students. Language learners benefit from having written transcripts alongside audio for pronunciation practice.

Media and Subtitling

Local television and radio stations produce content in Kalmyk. Automatic subtitle generation (SRT/VTT) makes these programs accessible to deaf and hard-of-hearing viewers. It also enables translation into Russian or other languages for wider distribution.

Academic Research

Linguists studying Mongolic languages, vowel harmony, or minority language documentation can transcribe field recordings quickly. Speechyou's export features allow integration with linguistic analysis tools.

How Speechyou Helps

Speechyou offers a simple interface for uploading audio or video files in Kalmyk. The AI processes the speech and outputs text in the correct Cyrillic orthography. Users can edit the transcript, generate subtitles, or export the text. The Solo plan includes unlimited transcription minutes, making it cost-effective for long recordings. With support for multiple dialects and a focus on accuracy, Speechyou is a practical solution for anyone working with the Kalmyk language.
