Yemba Speech to Text: Preserving a Language Through AI

The Yemba Language and Its Speakers

Yemba (Yɛmba) is a Grassfields Bantu language spoken predominantly in the Western Region of Cameroon, particularly in the departments of Menoua and Mifi. It is the mother tongue of the Bamileke people in areas such as Bafou, Dschang, and Fongo-Tongo. With around 300,000 speakers, Yemba is vibrant but remains under-resourced in terms of digital tools. Most speakers are bilingual in French or English, but the language is central to daily communication, oral traditions, and community identity.

Why Accurate Yemba Speech to Text Matters

Oral tradition is the backbone of Yemba culture. Stories, proverbs, and historical accounts are passed down through spoken word. Transcribing these recordings into text is vital for preservation, education, and accessibility. Speech-to-text technology enables:

• Archiving elders' knowledge before it is lost
• Creating subtitles for Yemba-language media
• Supporting literacy by providing written versions of oral content
• Assisting researchers in documentary linguistics

Moreover, for Yemba speakers in the diaspora, text versions of family recordings help maintain connection to their heritage.

Transcription Challenges: Tones, Dialects, and Data Scarcity

Yemba's tonal system is the primary obstacle for ASR. The language uses four distinct tones (high, mid, low, falling) that change meaning. For example, shú (head) versus shù (water) differ only by tone. Most commercial speech engines, trained on non-tonal languages, fail to capture these distinctions. Speechyou's model explicitly learns tonal contours through spectral analysis and language-specific training.

Dialectal diversity adds another layer. A speaker from Bafou uses different intonation and vocabulary than someone from Dschang. Without dialect awareness, a transcription system may misinterpret common words. Speechyou allows dialect selection during transcription, improving accuracy for regional varieties.

Finally, there is a lack of large transcribed Yemba datasets. Speechyou overcomes this via transfer learning from related Bantu languages and active learning from user corrections. This strategy gradually builds a more robust model without requiring millions of hours of pre-labeled data.

Use Cases in the Yemba Community

• Local Media: Radios like Radio Bafou can transcribe their broadcasts for online platforms, reaching younger audiences who prefer reading.
• Religious Organizations: Churches use subtitled sermon videos to share teachings with the diaspora.
• Education: Teachers convert oral lessons into text for classroom materials.
• Cultural Preservation: Families upload recordings of elders telling folktales and receive verbatim transcripts with timestamps.
