Urubú-Kaapor (Latin script) Speech to Text: A Complete Guide
Urubú-Kaapor Speech to Text: Preserving a Tupian Language with AI
The Kaapor Language and Its Speakers
Urubú-Kaapor (ISO 639-3: urb) is a Tupian language spoken by the Kaapor people in the Amazon rainforest of Brazil. With fewer than 2,000 speakers, it is classified as endangered. The language is rich in oral tradition, including myths, songs, and ceremonial speech. The Latin script is used for writing, but literacy rates are low, and most written materials are produced by linguists or missionaries. Accurate speech-to-text for Kaapor can bridge the gap between oral and written forms, helping to document and revitalize the language.
Why Accurate Speech-to-Text Matters for Kaapor
For indigenous languages like Kaapor, transcription is not just a technical convenience—it is a tool for survival. Every year, elder speakers pass away, taking with them irreplaceable knowledge. Transcribing audio recordings ensures that future generations can access the language even if they no longer hear it spoken daily. Additionally, speech-to-text enables the creation of subtitles for videos, which can be used in bilingual education programs. With Speechyou, Kaapor speakers can generate transcripts in minutes, without needing to hire expensive human transcribers.
Specific Transcription Challenges
Kaapor presents several challenges for automatic speech recognition:
- Nasal vowels: The language has six nasal vowel phonemes (ĩ, ẽ, ã, õ, ũ, ɨ̃) that must be distinguished from their oral counterparts.
- Glottal stop: The phoneme /ʔ/ occurs frequently and can change meaning (e.g., 'ka' meaning 'to burn' vs 'kaʔ' meaning 'to say').
- Tone and intonation: While not tonal, Kaapor uses pitch for emphasis and grammatical distinctions.
- Code-switching: Many speakers mix Portuguese words into Kaapor, requiring the ASR to handle both languages.
Speechyou's model is trained to handle these features, using a custom acoustic model and a language model that includes common Portuguese loanwords.
