Lugbara Speech to Text: Empowering a Central African Language with AI Transcription

Lugbara is a Central Sudanic language spoken by over 1.5 million people in the West Nile region of Uganda and the northeastern Democratic Republic of the Congo. It is the primary language of the Lugbara people, used in daily life, local government, radio, and education. Despite its size and importance, Lugbara has been largely neglected by the global speech technology industry. Most commercial speech-to-text services do not support it, leaving speakers without tools to transcribe audio, generate subtitles, or preserve oral content.

Why Accurate Speech-to-Text for Lugbara Matters

• Cultural preservation: Oral histories, folk tales, and traditional knowledge are passed down orally. Transcribing them creates a permanent record.
• Education: Teachers can create subtitles for Lugbara-language instructional videos, helping students learn in their native language.
• Media: Local radio stations and content creators need cost-effective transcription to repurpose broadcasts and reach wider audiences.
• Accessibility: Video subtitles in Lugbara make content accessible to the deaf and hard of hearing.
• Research: Linguists and anthropologists require accurate transcriptions for language documentation and analysis.

Specific Transcription Challenges

Lugbara presents unique challenges for automatic speech recognition:

• Tone: Three tones (high, mid, low) distinguish words. For example, átí (to kill) vs. àtí (to buy). The ASR model must capture pitch patterns.
• Vowel harmony: Lugbara has a vowel harmony system where vowels in a word must be either all [+ATR] or [-ATR]. The model must respect these constraints.
• Dialect variation: The two main dialects, Lugbara Proper and Aringa, differ in pronunciation and vocabulary. A robust system should handle both.
• Limited data: Few transcribed speech datasets exist for Lugbara. Speechyou uses transfer learning and community-driven data collection to build a reliable model.

Use Cases for Lugbara Transcription

• Podcasts: Lugbara-language podcasters can automatically generate show notes, transcripts, and social media captions.
• Subtitles for video: Create SRT and VTT files for films, news, and educational videos in Lugbara.
• Oral history archives: Convert interviews with elders into searchable text for museums and cultural centers.
• Accessibility: Provide real-time captions for Lugbara events and meetings.
