Guinea-Bissau Creole Speech to Text: Bridging the Digital Divide

Guinea-Bissau Creole, known affectionately as Kriol, is the vibrant lingua franca of Guinea-Bissau. Spoken by over 90% of the country's 2 million people, it serves as the primary language of trade, daily conversation, and cultural expression. Yet, for years, Kriol has been overlooked by mainstream speech recognition technology. Most commercial transcription tools, from Google Speech-to-Text to Rev, simply do not support it. This leaves a gap in accessibility for Kriol speakers who want to convert their spoken language into written text for subtitles, documentation, or analysis.

Why Accurate Kriol Transcription Matters

Accurate speech-to-text for Kriol is not just a technical challenge; it is a matter of digital equity. In Guinea-Bissau, literacy in Portuguese (the official language) is low, estimated at around 60%. Kriol is the language of the home, the market, and the radio. Transcribing it automatically can help:

• Preserve oral traditions and local knowledge.
• Create subtitles for videos in Kriol, improving accessibility.
• Support journalism by converting interviews into text.
• Enable academic research in linguistics and anthropology.
• Assist language learners to connect spoken and written forms.

Without a reliable tool, these tasks require manual transcription, which is time-consuming and expensive. Speechyou changes that by offering a dedicated Kriol speech-to-text model that is both accurate and affordable.

The Challenges of Transcribing Kriol

Kriol presents several unique challenges for automatic speech recognition. First, it is a low-resource language, meaning there is limited digital data available to train ASR models. Speechyou overcomes this by using transfer learning and data augmentation techniques, building on related Creole languages and augmenting with synthetic data.

Second, Kriol has four main dialects: Bissau, Cacheu, Bafatá, and Bijagós. These differ in pronunciation, particularly in vowels and certain consonants. Speechyou's model is trained on recordings from all four regions, ensuring it can handle the diversity of accents.

Third, code-switching with Portuguese is very common. Speakers often mix Kriol and Portuguese within the same sentence, especially in formal or educational contexts. Speechyou's multilingual architecture can distinguish between the two languages and transcribe each correctly.

Finally, Kriol's orthography is not standardized. While it uses the Latin script, different writers may spell the same word differently. Speechyou allows users to customize the output to their preferred spelling, making it flexible for various use cases.

Use Cases for Kriol Transcription

Podcasts and radio: Many community radio stations in Guinea-Bissau broadcast in Kriol. Transcribing their shows can create written archives, improve searchability, and provide content for websites.

Subtitles for local video: From YouTube vlogs to educational documentaries, adding Kriol subtitles makes content accessible to deaf viewers and helps learners follow along. Speechyou generates SRT and VTT files with ease.

Oral history preservation: Elders in rural villages hold valuable knowledge about traditional medicine, agriculture, and history. Transcribing their spoken stories in Kriol ensures this knowledge is not lost.

Academic research: Linguists studying Creole languages can use Speechyou to quickly transcribe field recordings, saving weeks of manual work.

Accessibility: For deaf individuals who read Kriol, captions in their language are essential. Speechyou makes it possible to add such captions to videos and live streams (via batch uploads).
