Lokoya Speech to Text: Transcribing a Nilotic Language with AI

The Lokoya language, a member of the Eastern Nilotic branch of the Nilo-Saharan family, is spoken primarily in the Eastern Equatoria region of South Sudan. With an estimated 30,000 speakers, Lokoya is a vital part of the cultural identity for the Lokoya people. However, like many minority languages, it faces challenges from dominant languages such as English and Arabic. Accurate speech-to-text technology offers a lifeline for documentation and revitalization.

Why Accurate Transcription Matters for Lokoya

Transcribing Lokoya audio is essential for several reasons:

• Cultural Preservation: Elders' stories, songs, and rituals can be recorded and transcribed to create a permanent written record.
• Education: Literacy materials in Lokoya help children learn to read in their mother tongue, improving early education outcomes.
• Accessibility: Subtitles in Lokoya make video content accessible to deaf or hard-of-hearing members of the community.
• Research: Linguists studying tonal languages rely on accurate phonetic transcriptions to analyze Lokoya's tonal patterns.

Transcription Challenges Specific to Lokoya

Lokoya presents unique difficulties for automatic speech recognition:

• Tonal Contrasts: Lokoya uses tone to distinguish word meanings. For example, a high tone on a syllable can change the word entirely. Speechyou's model incorporates tonal recognition to ensure accuracy.
• Limited Digital Corpus: Unlike major languages, there are few transcribed Lokoya datasets available for training. Speechyou uses transfer learning from related Nilotic languages like Dinka and Nuer to bootstrap performance.
• Dialectal Variation: The three main dialect groups — Central, Northern, and Southern — show variation in pronunciation and vocabulary. Speechyou allows users to specify the dialect for better results.
