Tewa Speech-to-Text: Preserving a Tanoan Language with AI

Tewa is a Tanoan language spoken by the Pueblo people of northern New Mexico. It is a language of deep cultural significance, used in ceremonies, oral histories, and daily life in communities like Ohkay Owingeh, San Ildefonso, Santa Clara, Tesuque, Nambe, and Pojoaque. With fewer than 2,000 speakers, Tewa is considered endangered, and efforts to revitalize it rely heavily on technology. Accurate speech-to-text for Tewa is a powerful tool for language preservation, education, and accessibility.

Why Accurate Tewa Transcription Matters

Transcribing Tewa audio is not just about converting speech to text. It is about capturing the nuance of a language that uses tone to distinguish meaning. For example, the word "p'ó" with a high tone means "water," while "p'ò" with a low tone means "path." Without accurate tone recognition, a transcription can be misleading. Speechyou's AI is trained to detect these tonal patterns, ensuring that the written output faithfully represents the spoken word.

Challenges in Tewa Speech Recognition

• Tonal system: Tewa has three tones (high, low, falling) that can change the meaning of words. Speechyou's model uses pitch tracking to differentiate them.
• Ejective consonants: Sounds like /pʼ/, /tʼ/, /kʼ/ are common in Tewa and are rare in many other languages. The model is trained on phonetic data to recognize these bursts.
• Dialectal variation: Tewa has several dialects with differences in pronunciation and vocabulary. Speechyou's model is trained on a multi-dialect corpus to generalize better.
• Limited data: As a low-resource language, Tewa has few transcribed corpora. Speechyou uses transfer learning and data augmentation to build a robust model.

Use Cases for Tewa Speech-to-Text

• Language revitalization: Schools and community programs can use transcribed texts to create reading materials and subtitled videos for learners.
• Oral history preservation: Recordings of elders telling stories can be transcribed and archived, allowing future generations to study the language.
• Tribal media: Radio stations and YouTube channels producing Tewa content can add subtitles, making their work accessible to a broader audience.
• Academic research: Linguists can transcribe field recordings more quickly, analyzing syntactic and phonological patterns.
• Accessibility: Real-time transcription during meetings helps elders who are hard of hearing or prefer reading to follow conversations.

How Speechyou Helps

Speechyou offers a dedicated Tewa speech-to-text model that is accessible through a simple web interface or API. It supports:

• Real-time and batch transcription.
• Speaker diarization (identifying who spoke when).
• Export to SRT, VTT, or plain text.
• Custom vocabulary for specialized terms (e.g., ceremonial names, place names).

The model is included in the Solo plan with unlimited transcription, making it affordable for individuals and small organizations. By providing accurate ASR for Tewa, Speechyou helps bridge the digital divide for indigenous languages.

The Future of Tewa in the Digital Age

With continued use and feedback from the Tewa community, Speechyou's model can be refined to handle even more diverse accents and recording conditions. As more Tewa speakers use the tool, the data will improve the model's accuracy. This is a step toward ensuring that Tewa remains a living language, not just in oral tradition but also in the digital world.
