Bissa Speech to Text: Transcribing a Mande Language with AI

Bissa (ISO 639-3: bib) is a Mande language spoken by the Bissa people in West Africa, primarily in Burkina Faso, with smaller communities in northern Ghana and Togo. Estimates place the number of speakers at around 350,000. The language uses a Latin-based orthography developed by missionaries and linguists, and it is recognised as a national language in Burkina Faso. Despite its cultural richness, Bissa has very few digital resources, making automatic speech recognition a challenge.

Why Accurate Bissa Transcription Matters

Oral tradition is central to Bissa culture. Elders pass down history, proverbs, and songs orally, and much of this knowledge remains undocumented. With accurate speech-to-text, communities can create written archives of their heritage. Additionally, Bissa-language media — such as community radio programs and podcasts — can reach wider audiences when transcripts and subtitles are available. For the diaspora, transcribed family videos help maintain language ties across generations.

Transcription Challenges Specific to Bissa

Bissa presents several hurdles for automatic speech recognition:

• Tonal distinctions: Three tones (high, mid, low) change word meanings. For example, 'bá' (father) vs 'bà' (mother).
• Vowel quality: Contrasts between short and long vowels, and between oral and nasal vowels (e.g., 'ka' vs 'kã').
• Dialectal variation: Four main dialects with differences in pronunciation and lexicon.
• Limited training data: Few publicly available transcribed Bissa audio corpora.

Speechyou tackles these challenges with a specialised Bissa model that uses transfer learning from related Mande languages and continuous fine-tuning with user-submitted data.
