Birifor Speech to Text: Preserving a Language Through AI

Birifor is a Gur language spoken by around 100,000 people in the southwestern regions of Burkina Faso and northern Côte d'Ivoire. It belongs to the Oti-Volta branch of the Niger-Congo family and is closely related to Dagaare and Moore. The language is written in a Latin script with additional characters for tones and vowel length, such as 'ɛ', 'ɔ', and 'ĩ'. Despite its relatively small speaker population, Birifor has a rich oral tradition of folktales, proverbs, and ceremonial speeches that are passed down through generations.

Why Accurate Birifor Speech-to-Text Matters

For Birifor speakers, accurate speech-to-text is not just a convenience; it is a tool for cultural preservation. Many Birifor elders are the last fluent speakers of certain dialects, and their knowledge of traditional medicine, farming practices, and history is at risk of being lost. By transcribing oral recordings into written form, communities can archive this wisdom for future generations. Additionally, Birifor-language media, such as radio programs and YouTube videos, can reach wider audiences when subtitles are available.

Transcription Challenges for Birifor

Birifor presents several challenges for automatic speech recognition:

• Tonal distinctions: Birifor uses three phonemic tones (high, mid, low). For example, 'bá' (to come) vs. 'bà' (to go) differ only in tone. Generic ASR models often ignore tone, leading to errors.
• Vowel harmony: The language has a system where vowels in a word must share certain features (e.g., advanced tongue root). This affects pronunciation and must be modeled correctly.
• Dialectal variation: Southern Birifor and Northern Birifor differ in vocabulary and pronunciation. A model trained on one dialect may fail on the other.
• Limited training data: Unlike major world languages, Birifor has few publicly available transcribed recordings. Most data comes from Bible translations or linguistic fieldwork.

Speechyou addresses these challenges with a specialized Birifor model that incorporates tone marking, vowel harmony rules, and dialect-specific training. The system can be fine-tuned with user-provided recordings, improving accuracy over time.
