Warji Speech to Text: Preserving a Language Through AI

Warji is a Chadic language spoken by approximately 150,000 people in northern Nigeria, primarily in the states of Bauchi and Jigawa. It is part of the West Chadic branch of the Afro-Asiatic language family, related to Hausa but distinct in its phonology and grammar. The language is written in the Latin script, though many speakers are more comfortable with oral communication.

Why Accurate Warji Transcription Matters

For a minority language like Warji, speech-to-text technology is not just a convenience; it is a tool for cultural preservation and community empowerment. Oral traditions, folk tales, and historical narratives are passed down verbally, and without written records, they risk being lost. Accurate transcription allows these stories to be archived, studied, and shared with future generations.

Moreover, Warji speakers who create video content—whether for religious teachings, agricultural advice, or entertainment—can now add subtitles in their own language, reaching a wider audience and improving accessibility for the hearing impaired.

Challenges in Warji Automatic Speech Recognition

Developing ASR for Warji comes with unique challenges:

• Tonal system: Warji uses three distinct tones (high, mid, low) to differentiate words. For example, tà (low tone) means 'to eat', while tá (high tone) means 'to sell'. Our model uses pitch tracking and context to resolve these.
• Vowel harmony: Words must have vowels from the same harmonic set. This affects suffixes and can confuse models that treat vowels independently.
• Limited training data: Unlike English or Spanish, Warji lacks large publicly available speech corpora. Speechyou leverages transfer learning from related languages and allows users to contribute recordings.
• Dialectal variation: Central, Northern, and Southern Warji differ in vocabulary and pronunciation. Our system supports separate dialect profiles to maintain accuracy.

Use Cases for Warji Speech-to-Text

• Oral history preservation: Transcribe interviews with elders and community leaders.
• Video subtitling: Generate SRT/VTT files for Warji-language YouTube videos.
• Language learning: Convert spoken lessons into text for study materials.
• Research: Linguists can quickly transcribe field recordings for analysis.
• Accessibility: Provide text alternatives for Warji audio content.
