Toura (Neb) Speech to Text: Preserving a Mande Language with AI

The Toura Language and Its Speakers

Toura, also known as Neb, is a Mande language spoken by approximately 100,000 people in the Ivory Coast, primarily in the region around the town of Toura. The language belongs to the southern Mande branch and is closely related to other languages like Guro and Yaure. Toura is rich in oral tradition, with elders passing down histories, proverbs, and songs. However, like many minority languages, it faces pressure from French, the official language of Ivory Coast, and from larger regional languages. Speech-to-text technology offers a powerful means to document and revitalize Toura.

Why Accurate Speech-to-Text Matters for Toura

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

• Language preservation: Transcribing oral histories and folk tales creates a permanent written record.
• Education: Teachers can create Toura language learning materials, including subtitles for videos.
• Media: Local radio and television stations can subtitle their Toura-language content, reaching a wider audience.
• Accessibility: Deaf and hard-of-hearing Toura speakers can access spoken content through captions.

Without reliable transcription tools, these efforts are slow and expensive. Human transcription is scarce for Toura, and most commercial speech recognition systems do not support the language at all.

Challenges in Transcribing Toura

Toura presents several unique challenges for automatic speech recognition:

• Tonal system: Toura uses three tones (high, mid, low) to distinguish words. For example, the word "ba" can mean "father" or "go" depending on tone. Speechyou's model is trained to detect these tonal differences.
• Limited data: As a low-resource language, there are few recorded speech datasets. Speechyou uses transfer learning from related languages and allows users to contribute their own recordings to improve accuracy.
• Dialectal variation: Toura has Northern, Central, and Southern dialects, each with distinct phonological features. The system handles multiple dialects in a single model.
• Vowel harmony: The language requires vowels within a word to be from the same class (e.g., front or back). The transcription engine respects these rules to avoid grammatical errors.
