Emberá-Catío Speech to Text: Preserving an Indigenous Language with AI

Emberá-Catío, known simply as "Emberá" by its speakers, is a Chocó language spoken primarily in the tropical rainforests of Colombia and Panama. With around 10,000 speakers, it is a minority language rich in oral tradition. The Emberá people have a deep connection to their language, which carries stories, laws, and knowledge of the forest. However, as younger generations increasingly adopt Spanish, the need for digital tools to transcribe, subtitile, and archive Emberá-Catío has never been greater.

Why Accurate Transcription Matters

Transcription of Emberá-Catío audio is critical for several reasons:

• Language preservation: Oral histories and songs can be turned into written records.
• Education: Bilingual schools can use subtitled videos to teach reading in Emberá.
• Research: Linguists and anthropologists can analyze spoken material without manual transcription bottlenecks.
• Accessibility: Deaf Emberá community members who read the written form can access spoken content.
• Media production: Podcasts, radio shows, and documentaries can be captioned for wider audiences.

Unique Challenges in Transcribing Emberá-Catío

Emberá-Catío has phonological features that make automatic speech recognition (ASR) difficult for generic systems:

• Nasalized vowels: The language contrasts oral and nasal vowels. For example, "ã" is different from "a". Many ASR models treat them as the same.
• Prenasalized consonants: Sounds like [mb] and [nd] are single phonemes, but they can be misrecognized as sequences.
• Low digital footprint: Most training data for ASR is in high-resource languages. Emberá-Catío has very little online text or audio, which means models must be built from scratch or adapted carefully.

How Speechyou Handles Emberá-Catío

Speechyou has developed a dedicated speech-to-text model for Emberá-Catío using a combination of supervised learning from field recordings and transfer learning from related Emberá varieties. The model is trained to recognize nasal vowels, prenasalized stops, and the unique intonation patterns of the language. Users can simply upload an audio or video file, select "Emberá-Catío" from the language list, and receive an accurate transcript with timestamps. The output can be exported as SRT or VTT subtitles, perfect for video content.

Use Cases in the Community

• Oral history preservation: Emberá elders can record stories and have them automatically transcribed, creating a digital archive.
• Classroom materials: Teachers can create subtitled videos in Emberá-Catío for language classes.
• Legal and health services: Interpreters can transcribe consultations to ensure accurate records in both Emberá and Spanish.
• Cultural documentation: Museums and cultural centers can transcribe interviews with artisans and healers.
