Guajajára Speech to Text: Preserving the Awá Language with AI
Guajajára, known natively as Awá, is a Tupí-Guaraní language spoken by the Guajajára people in the Brazilian state of Maranhão. With around 13,000 speakers, it is one of the more vibrant indigenous languages in the region, yet it remains under-resourced in terms of digital tools. Accurate speech-to-text technology for Guajajára can open doors to language preservation, education, and cultural expression.
Why Accurate Guajajára Speech-to-Text Matters
For the Guajajára community, transcription tools are not just a convenience; they are a bridge to the modern world. Elders' oral histories, traditional songs, and everyday conversations can be captured in writing, creating a permanent record for younger generations. Educators can produce subtitled videos in Guajajára for schools, and activists can transcribe community meetings for advocacy. Without reliable ASR, this work falls to manual transcription, which is slow and expensive.
Specific Transcription Challenges
Phonology: Nasal Vowels and Glottal Stop
Guajajára has a complex phonology that includes six nasal vowels (ã, ẽ, ĩ, õ, ũ, ỹ) and a phonemic glottal stop /ʔ/. These sounds are not present in Portuguese or English, so most speech-to-text engines ignore or misrepresent them. Speechyou's model is trained to detect these features, ensuring that words like "nhe'enga" (speech) are transcribed correctly rather than as "nheenga" without the glottal stop.
Low Resource Data
Unlike widely spoken languages, Guajajára has few publicly available transcribed audio datasets. This makes it challenging for generic ASR providers to justify support. Speechyou uses a combination of active learning and community contributions to grow its model. Every transcription you correct helps improve accuracy for everyone.
Dialectal Variation
There are at least three main dialect groups: Eastern, Western, and Pindaré. They differ in vowel pronunciation, consonant clusters, and vocabulary. For example, the word for "good" may be pronounced differently across regions. Speechyou allows users to select the dialect of their audio, and we maintain separate acoustic models to better match each variety.
