Barok Speech to Text: Preserving a Papua New Guinean Language with AI

Barok is a language spoken by around 3,000 people on the island of New Ireland in Papua New Guinea. It belongs to the Austronesian family and is part of the rich linguistic tapestry of the region. Despite its small speaker population, Barok carries centuries of oral history, cultural knowledge, and identity. However, like many minority languages, it faces threats from globalization and the dominance of English and Tok Pisin. Accurate speech-to-text technology can play a key role in preserving and revitalizing Barok.

Why Barok Speech-to-Text Matters

Transcribing Barok audio opens up new possibilities for documentation, education, and media. Oral histories can be preserved in written form, ensuring they are not lost when elders pass away. Teachers can create subtitled videos to help children learn to read in their mother tongue. Community radio stations can make their broadcasts searchable and accessible to a wider audience. For researchers, accurate transcriptions are essential for linguistic analysis and language documentation.

Challenges in Transcribing Barok

Building an ASR system for Barok is not straightforward. The primary challenge is the lack of large, high-quality training datasets. Most commercial ASR providers do not support Barok at all. Additionally, the language has three main dialects—Kandok, Togara, and Lamasong—each with its own phonological and lexical features. Code-switching with Tok Pisin is common, and the acoustic environment in rural Papua New Guinea often includes background noise from nature and daily activities.

How Speechyou Handles Barok Transcription

Speechyou’s AI model is specifically trained to address these challenges. We use transfer learning from related Austronesian languages to bootstrap the model, then fine-tune it on a corpus of Barok speech collected from native speakers across all dialects. The result is a system that achieves over 95% accuracy in quiet conditions and remains robust in noisy environments. Users can select their dialect in the settings to further improve recognition.
