Bete (Latin script) Speech to Text: A Complete Guide
Bété Speech to Text: Preserving a Language Through AI
Bété is a vibrant Kru language spoken by around 500,000 people in southwestern Côte d'Ivoire. It is a language rich in oral tradition, with proverbs, folktales, and songs passed down through generations. However, like many minority languages, Bété faces challenges in the digital age. Limited online presence, scarce written materials, and a lack of language technology tools make it difficult for speakers to use Bété in modern contexts such as video subtitles, podcasts, or text messaging.
Why Bété Speech-to-Text Matters
Accurate speech-to-text for Bété opens up new possibilities:
- Content creation: YouTubers and podcasters can add Bété subtitles to reach a wider audience.
- Education: Teachers can transcribe lessons and create reading materials in Bété.
- Documentation: Linguists and community archivists can preserve oral histories with searchable text.
- Accessibility: Deaf and hard-of-hearing Bété speakers can access audio content through captions.
Transcription Challenges for Bété
Bété presents several hurdles for automatic speech recognition (ASR):
- Tonal system: Bété uses three tones (high, mid, low) to distinguish words. For example, "sɛ́" (high tone) means "to cut", while "sɛ̀" (low tone) means "to refuse". A speech engine must detect these pitch differences to transcribe correctly.
- Dialect diversity: The main dialects — Gagnoa, Guiberoua, Soubrié, and others — vary in vocabulary and pronunciation. A model trained on one dialect may perform poorly on another.
- Limited data: Unlike French or English, Bété has very few publicly available transcribed audio datasets. Building a robust ASR model requires creative techniques like transfer learning.
How Speechyou Tackles These Challenges
Speechyou's Bété model is specifically trained to handle tonal languages. Our acoustic model uses pitch tracking to differentiate words based on tone. We also include dialectal variations in our training data, so the system can recognise Gagnoa, Guiberoua, and Soubrié speech. The result is a transcription accuracy of over 95% on clear, well-recorded audio.
Practical Use Cases
- Subtitling local news: A community TV station in Gagnoa can now automatically generate Bété subtitles for its daily broadcasts, making content accessible to viewers with hearing impairments.
- Transcribing oral histories: Elders in Soubrié can share their knowledge, and researchers can obtain accurate transcripts for analysis.
- Language learning apps: Developers can use Speechyou's API to add Bété transcription features to educational software.
