Gulay Speech to Text: Preserving a Language Through AI

The Gulay Language and Its Speakers

The Gulay language, also known as Gulay or Gulai, is spoken by approximately 200,000 people in the southwestern part of Chad, particularly in the Mayo-Kebbi Est region. It belongs to the Adamawa-Ubangi subgroup of the Niger-Congo language family and is written in the Latin script. The language has several dialects, including Western, Eastern, and Southern Gulay, which vary slightly in pronunciation and vocabulary. Despite its relatively small speaker population, the language is a vital part of the cultural identity of the Gulay people.

Why Accurate Speech-to-Text for Gulay Matters

Accurate speech-to-text for Gulay is not just a technical achievement; it is a tool for cultural preservation and accessibility. Many Gulay speakers are bilingual in French or Arabic, but the Gulay language remains the primary means of communication in homes and community gatherings. Transcribing oral histories, traditional stories, and everyday conversations into text helps preserve the language for future generations. Moreover, it enables the creation of educational materials and subtitles for media, making Gulay content accessible to a wider audience.

Transcription Challenges Specific to Gulay

Gulay presents several unique challenges for automatic speech recognition:

• Tonal distinctions: Gulay is a tonal language, meaning that pitch changes can alter the meaning of a word. For example, a word pronounced with a high tone may mean something entirely different from the same phonetic sequence with a low tone. The ASR model must be sensitive to these tonal differences.
• Vowel harmony: The language exhibits vowel harmony, where vowels within a word must belong to a specific class (e.g., advanced or retracted tongue root). This can cause allophonic variation that the recognizer must handle.
• Limited data: As a low-resource language, there are few publicly available transcribed speech datasets. This scarcity makes training a robust ASR system difficult. Speechyou overcomes this by leveraging transfer learning from related languages and augmenting data with synthetic speech.

Despite these challenges, Speechyou's Gulay model achieves high accuracy by focusing on the linguistic features that matter most.
