Dangaléat Speech to Text: Preserving a Chadic Language with AI
Dangaléat is a Chadic language spoken by around 60,000 people in the Guéra region of Chad. It belongs to the East Chadic branch of the Afro-Asiatic family and is written in the Latin script. Like many minority languages, Dangaléat faces challenges in the digital age, including a lack of online content and limited support from mainstream technology. Accurate speech-to-text tools can help preserve and promote the language.
Why Accurate Dangaléat Transcription Matters

Transcription Challenges Specific to Dangaléat
Dangaléat presents unique difficulties for automatic speech recognition:
- Tonal contrasts: Three lexical tones (high, mid, low) can change word meaning. For example, bàl (to be) vs. bál (to cut).
- Vowel length: Long and short vowels are phonemic, as in dàr (to buy) vs. dàar (to cry).
- Dialectal variation: Central, Western, and Korbo dialects differ in vocabulary and pronunciation.
- Limited training data: Few digitized recordings exist, making model training challenging.
