Kafa Speech to Text: Preserving a Language Through AI Transcription

Kafa, also known as Keficho, is a North Omotic language spoken by around 800,000 people in the Kafa Zone of southwestern Ethiopia. It belongs to the Omotic branch of the Afroasiatic language family and is written in the Latin script. The language has a rich oral tradition, including folk tales, proverbs, and historical narratives that have been passed down through generations. However, like many minority languages, Kafa faces challenges in the digital age, including limited online content and lack of language technology support.

Why Accurate Kafa Speech-to-Text Matters

Accurate speech-to-text for Kafa is crucial for several reasons:

• Cultural preservation: Transcribing oral histories and traditional stories ensures they are documented for future generations.
• Education: Teachers can create subtitles for educational videos in Kafa, making learning materials more accessible.
• Media and communication: Local radio stations and community broadcasters can generate captions for news and programs.
• Research: Linguists and anthropologists can transcribe interviews and field recordings quickly.
• Accessibility: Deaf or hard-of-hearing Kafa speakers can access audio content through subtitles.

Specific Transcription Challenges for Kafa

Transcribing Kafa presents several challenges that Speechyou's AI has been designed to handle:

• Tonal system: Kafa uses pitch to distinguish words. For example, the word 'bó' (to come) and 'bò' (to go) differ only in tone. Our model is trained to recognize these tonal patterns.
• Ejective and implosive consonants: Kafa has sounds like /kʼ/ and /ɓ/ that are rare in many languages. Accurate acoustic modeling is needed to transcribe them correctly.
• Dialectal variation: Dialects such as Bonga, Gimira, and Sheka have different pronunciations and vocabulary. Speechyou supports multiple dialect models.
• Limited training data: With few digital resources, we use transfer learning from related Omotic languages to bootstrap the model.
