Marba Speech to Text: Preserving a Chadic Language with AI

Marba is a Chadic language spoken by around 250,000 people in southwestern Chad, primarily in the regions of Mayo-Kebbi Est, Tandjilé, Logone Occidental, and Chari-Baguirmi. As a member of the Masa subgroup of the Afro-Asiatic family, Marba shares features with neighboring languages like Massa and Musey. Despite its relatively small speaker population, the language plays a vital role in community identity, oral tradition, and local governance. However, like many minority languages, Marba faces pressures from dominant languages such as French and Arabic. Digital tools that support Marba can help strengthen its presence in modern media and education.

Why Accurate Marba Transcription Matters

Oral communication is the backbone of Marba society. Stories, proverbs, historical accounts, and legal agreements are passed down verbally. Converting this spoken heritage into written form is essential for preservation, education, and accessibility. Accurate Marba speech to text enables:

• Cultural preservation: Transcribing interviews with elders ensures that traditional knowledge is not lost.
• Education: Teachers can create written materials for literacy programs.
• Media: Community radio stations can produce subtitled content for wider reach.
• Healthcare: Health messages can be documented and shared accurately.
• Legal processes: Court proceedings and witness statements can be recorded in writing.

Without reliable transcription, these efforts remain dependent on manual work, which is slow and costly. AI-powered transcription offers a scalable solution.

Challenges in Transcribing Marba Audio

Developing automatic speech recognition for Marba comes with unique hurdles:

• Tonal system: Marba uses tone to distinguish meaning. For example, 'kà' (to go) vs. 'ká' (to come). Generic ASR models often miss these distinctions.
• Vowel harmony: Vowels within a word must agree in features like height or backness. This requires the model to understand morphophonological rules.
• Dialectal variation: Differences in pronunciation and vocabulary across regions. A model trained on one dialect may fail on another.
• Limited digital resources: Marba has few transcribed datasets, making it a low-resource language for AI.

Speechyou addresses these challenges through specialized acoustic modeling, dialect selection, and transfer learning from related languages.
