Bakoko Speech to Text: Preserving a Cameroonian Language with AI

Bakoko is a Bantu language spoken in the forests of central Cameroon, primarily by communities in the Littoral and Centre regions. It belongs to the larger Bantu family that stretches across sub-Saharan Africa. With around 150,000 speakers, Bakoko is considered a vulnerable language, as younger generations increasingly use French or English in daily life. Digitisation offers a pathway to document and revitalise the language, and accurate speech-to-text technology is a key component.

Why Accurate Bakoko Transcription Matters

Recording and transcribing spoken Bakoko helps preserve oral history, folktales, and indigenous knowledge. Researchers, community leaders, and educators need reliable tools to convert audio into text. Until recently, no commercial speech-to-text service supported Bakoko. Speakers had to rely on manual transcription, which is time-consuming and costly. Speechyou bridges this gap with a dedicated model for Bakoko that understands its tonal system and dialectal variations.

The Linguistic Challenge of Bakoko

Like many Bantu languages, Bakoko is tonal. The same sequence of consonants and vowels can have different meanings depending on pitch. For example, the word "bɔ́lɔ́" (to be sick) vs. "bɔ̀lɔ̀" (a type of tree) differ only by tone. Standard ASR models struggle with such distinctions if they are not trained on tonal data. Speechyou’s model incorporates pitch tracking and uses language models that are aware of tone minimal pairs.

Another challenge is dialectal diversity. Bakoko has several regional variants:

• Yambetta – notable for lenition of certain consonants
• Bafia – influenced by neighbouring languages like Bassa
• Ndikiniméki – retains older consonant clusters
• Bokito – exhibits vowel harmony shifts

Speechyou’s base model is trained on a multi-dialect corpus, but users can upload dialect-specific audio for improved accuracy. The system adapts to the input without requiring extensive retraining.

Specific Use Cases for Bakoko

• Oral history preservation: Elders’ recordings of traditions and proverbs can be transcribed and archived.
