Rapa Nui Speech-to-Text: Preserving the Language of Easter Island with AI

Rapa Nui (Reo Rapa Nui) is the native language of the Rapa Nui people, the inhabitants of Easter Island (Rapa Nui) in the southeastern Pacific Ocean. A member of the Polynesian language family, it is closely related to Tahitian and Māori, but has developed its own unique phonology and vocabulary over centuries. Today, the language is spoken by approximately 2,000 to 5,000 people, most of whom live on the island or in diaspora communities in Chile. Despite its small speaker population, Rapa Nui holds immense cultural significance, and efforts to revitalize it are gaining momentum through education, media, and digital tools.

Why Accurate Speech-to-Text for Rapa Nui Matters

Transcription plays a vital role in language preservation. It allows elders' stories, songs, and everyday conversations to be recorded and studied. It also enables the creation of subtitles for videos, making cultural content accessible to both Rapa Nui learners and the wider world. For the Rapa Nui community, having a reliable speech-to-text tool means they can document their oral history without relying on costly manual transcription. It also supports bilingual education, where children can see Rapa Nui text alongside Spanish while listening to native speakers.

Key Challenges in Transcribing Rapa Nui

• Limited data: Most ASR models require thousands of hours of training data. Rapa Nui has very few publicly available transcribed corpora.
• Phonemic contrasts: The glottal stop (ʻ) and vowel length are meaningful and must be transcribed accurately.
• Code-switching: Speakers frequently mix Rapa Nui and Spanish, sometimes within a single sentence.
• Noise: Many recordings are made outdoors, capturing wind, waves, and crowd sounds typical of island life.
