Hahon Speech to Text: Preserving a Papua New Guinea Language with AI

Hahon is an Austronesian language spoken by approximately 10,000 people in the New Ireland Province of Papua New Guinea. It is the mother tongue of the Hahon people, who live in the coastal and inland areas south of the Kavieng district. Like many small languages, Hahon faces pressures from Tok Pisin, the national lingua franca, and English, the language of education. Yet the Hahon community remains proud of their language, using it in homes, churches, and traditional ceremonies. Accurate speech-to-text technology can help bridge the gap between oral tradition and digital documentation.

Why Accurate Hahon Transcription Matters

For a language as small as Hahon, every piece of recorded speech is valuable. Elders hold unique knowledge of medicinal plants, oral history, and folklore that has never been written down. By transcribing these recordings, we create a permanent archive that can be read, searched, and studied. Hahon transcription also supports literacy: children who learn to read in their mother tongue before transitioning to English have better educational outcomes. With Speechyou, anyone can convert Hahon audio into text without needing a linguist or typing skills.

Specific Challenges for Hahon ASR

Developing automatic speech recognition for Hahon comes with unique hurdles:

• Vowel length distinction: Minimal pairs like /tana/ (coconut) vs /ta:na/ (to stand) require the model to detect subtle duration differences.
• Code-switching: Many Hahon speakers insert Tok Pisin words or phrases. The system must output both languages correctly.
• Background noise: Field recordings often contain village sounds, wind, or multiple speakers. Speechyou uses noise suppression preprocessing.
• Dialectal variation: North and South Hahon have different pronunciations of certain words. The model is trained on both variants.
• Limited data: Only a few hours of transcribed Hahon speech exist. Speechyou augments this with synthetic data and transfer learning from related languages like Nalik and Tigak.

Use Cases Across the Hahon Community

• Preserving oral history: Transcribe interviews with elders about traditional customs and place names.
• Creating subtitles for church services: Upload sermons in Hahon and generate SRT files for projection during services.
• Supporting bilingual education: Teachers can produce subtitled videos in Hahon for subjects like science and social studies.
• Accessibility for the deaf: Deaf community members who read Hahon can follow along with subtitles.
• Language research: Linguists can quickly transcribe field recordings for phonetic and grammatical analysis.
• Local media: YouTube channels and community radio stations can add Hahon subtitles to reach a wider audience.
• Family communication: Record and transcribe messages from relatives abroad to share with non-speaking family members.
