Pijao Speech to Text: Preserving an Endangered Language with AI

The Pijao language, known natively as Pijao, is a critically endangered indigenous language of Colombia. It was historically spoken by the Pijao people in the departments of Tolima and Huila, including areas around Coyaima, Natagaima, and the central Pijao region. Today, only a few dozen fluent speakers remain, and the language is at risk of disappearing. However, efforts are underway to revive and document Pijao, and modern technology — especially speech-to-text — plays a vital role.

Why Accurate Pijao Speech-to-Text Matters

For the Pijao community, having the ability to transcribe spoken Pijao into written text is essential for several reasons. First, it allows elders to share their knowledge and stories in a form that can be preserved and studied. Second, it supports language teaching: learners can hear the language and see the written form simultaneously. Third, it enables the creation of subtitles for videos, making content accessible to a wider audience, including those who are not fluent in Spanish.

Speechyou offers a dedicated Pijao speech-to-text model that understands the unique phonology of the language. Pijao features sounds like glottal stops, vowel length contrasts, and consonant clusters that are rare in other languages. Generic ASR systems fail to recognize these, but Speechyou's model is trained to handle them.

Transcription Challenges for Pijao

Transcribing Pijao is not straightforward. The language has three main dialects: Coyaima, Natagaima, and Pijao proper. Each has its own pronunciation and vocabulary. Additionally, there is very little existing digital audio data — most recordings are from field linguists and community archives. Speechyou overcomes this by:

• Using transfer learning from related languages.
• Allowing users to upload their own audio to improve the model.
• Offering dialect-specific models for better accuracy.

Another challenge is the lack of a standardized orthography. While the language is written in Latin script, there are variations in how sounds are represented. Speechyou uses a consistent orthography based on the most common conventions used in revitalization work.

Use Cases for Pijao Transcription

• Oral History Preservation: Transcribe interviews with elders to create a digital archive of Pijao stories, songs, and traditional knowledge. This ensures the language is not lost when the last speakers pass away.
• Education: Generate subtitles for Pijao language classes and online courses. Learners can follow along with the text as they listen, improving comprehension.
• Community Media: Transcribe radio programs and podcasts in Pijao, making them searchable and shareable. This helps spread the language beyond the immediate community.
• Linguistic Research: Provide researchers with accurate transcriptions for phonological and grammatical analysis. This contributes to the scientific understanding of the language.
• Accessibility: Offer real-time captioning for Pijao community meetings and events, ensuring that even those with hearing impairments can participate.
