Oroko Speech to Text: Preserving a Bantu Language with AI

Oroko is a Bantu language spoken by around 100,000 people in the Southwest Region of Cameroon, mainly in the Ndian and Meme divisions. It is part of the broader Bantu family that includes Swahili and Zulu, but unlike those languages, Oroko has very few digital resources. Accurate speech-to-text for Oroko is essential for preserving oral traditions, supporting bilingual education, and enabling local media production.

Why Oroko Transcription Matters

• Cultural preservation: Elders hold vast knowledge in Oroko. Transcribing their stories ensures future generations can access them.
• Education: Schools in Oroko-speaking areas need subtitled materials for literacy programs.
• Accessibility: Deaf or hard-of-hearing community members benefit from subtitles in their native language.
• Research: Linguists studying Bantu languages require accurate transcriptions for analysis.

Challenges in Automatic Speech Recognition for Oroko

Oroko presents several challenges for ASR:

• Tone: Like many Bantu languages, Oroko uses pitch to distinguish meaning. For example, mbɔ́ (house) vs. mbɔ̀ (bag). Speechyou's model is trained to recognize these tonal contrasts.
• Vowel harmony: Oroko has a seven-vowel system with advanced tongue root harmony, which affects vowel pronunciation in context.
• Dialectal diversity: The language has at least four major dialects—Londo, Mbonge, Ekombe, and Bima—each with distinct phonetic and lexical features.
• Limited data: Few transcribed Oroko datasets exist. Speechyou uses transfer learning from related Bantu languages and data augmentation to overcome this.

How Speechyou Helps

Speechyou offers a dedicated Oroko speech-to-text engine that handles these challenges. Users can upload audio or video files and receive accurate transcriptions with timestamps. The system supports:

• Dialect detection: Automatically identifies whether the speech is Londo, Mbonge, or Ekombe and applies the correct model.
• Tone marking: Outputs tonal diacritics where needed for clarity.
• Subtitle generation: Exports SRT and VTT files for video captioning.
• Real-time mode: For live events like church services or community meetings.

Local radio stations in Kumba and Mundemba use Speechyou to subtitle news broadcasts in Oroko, reaching a wider audience. Schools in the Mbonge subdivision create subtitled lesson videos for science and math. Researchers from the University of Buea transcribe oral history interviews for a language documentation project. All of this is possible because Speechyou makes Oroko transcription accessible and affordable.
