Tagbanwa Speech to Text: Preserving an Indigenous Voice with AI

Tagbanwa is a Philippine language spoken by around 10,000 people in the province of Palawan. It is part of the Palawanic branch of Austronesian languages and is closely related to Palawano and Molbog. The language has three main dialects: Central, Northern, and Southern. Despite its small speaker population, Tagbanwa is a vital part of the cultural identity of the Tagbanwa people, who are known for their traditional tattoos, weaving, and oral epics.

Why Accurate Tagbanwa Speech-to-Text Matters

Oral tradition is the backbone of Tagbanwa culture. Stories of creation, heroic journeys, and ancestral laws are passed down through generations by word of mouth. However, with younger generations shifting to Filipino and English, these narratives are at risk of being lost. Transcribing Tagbanwa audio into text creates a permanent record that can be studied, translated, and shared. For linguists, anthropologists, and the community itself, accurate speech-to-text is a tool for language preservation.

Moreover, Tagbanwa is used in local governance and education. The Philippine government promotes mother-tongue-based multilingual education, and Tagbanwa is one of the languages used in early-grade instruction. Teachers need transcribed materials and subtitled videos to support learning. NGOs working in Palawan also require transcription of community meetings and interviews conducted in Tagbanwa.

Challenges in Tagbanwa Automatic Speech Recognition

Developing ASR for Tagbanwa comes with specific hurdles:

• Low digital resources: There are very few public datasets of Tagbanwa speech or text. Most ASR models are trained on major languages, so they fail on Tagbanwa without adaptation.
• Phonetic nuances: Tagbanwa distinguishes between short and long vowels, and glottal stops are phonemic. For example, "bata" (child) vs. "bata'" (carry) differ only by a glottal stop. Generic ASR often misses these contrasts.
• Dialectal variation: A word in Central Tagbanwa may be pronounced differently in Northern or Southern dialects. Without dialect-aware models, accuracy drops.

Speechyou addresses these challenges by using transfer learning from related languages (like Tagalog and Cebuano) and by offering dialect-specific model options. The AI is fine-tuned to recognize Tagbanwa phonemes, including glottal stops and vowel length, ensuring high accuracy even with limited training data.
