Preserving the Uma Language with AI Speech-to-Text

Uma is a minority language spoken in the highlands of Central Sulawesi, Indonesia. With around 20,000 speakers, it is an essential part of the region's cultural fabric. The language is used in daily conversation, traditional ceremonies, and local governance. However, like many small languages, Uma faces the risk of decline as younger generations shift to Indonesian. Accurate speech-to-text technology offers a powerful tool to document, teach, and revitalize the language.

Why Accurate Speech-to-Text for Uma Matters

Transcribing Uma audio is not just a technical convenience; it is a means of preserving oral history. Elders carry knowledge of traditional medicine, agriculture, and rituals that have never been written down. By converting spoken words into text, we create a permanent record that can be studied, shared, and used in schools. Additionally, subtitles in Uma enable deaf or hard-of-hearing community members to access local media.

Specific Challenges in Transcribing Uma

• Limited Training Data: Most ASR models are trained on major languages like English or Mandarin. Uma has almost no public datasets, making it necessary to build custom models from scratch.
• Dialectal Diversity: The three main dialects—Tobaku, Kulawi, and Pipikoro—have distinct phonetic and lexical features. A model trained on one dialect will perform poorly on another.
• Code-Switching: In everyday speech, Uma speakers frequently mix Indonesian words, especially for modern concepts. This bilingual context confuses standard language-specific models.

Use Cases for Uma Transcription

• Oral History Archives: Record and transcribe interviews with elders to create a digital library of traditional knowledge.
• Local Media: Generate subtitles for Uma-language radio programs and community videos, making them accessible to a wider audience.
• Education: Develop teaching materials for Uma language classes, including reading exercises and vocabulary lists.
• Research: Linguists can transcribe field recordings quickly, accelerating documentation efforts.
• Accessibility: Provide real-time captions for community meetings and religious services.
