Malayic Dayak Speech to Text: Preserving Borneo's Heritage Through AI

Malayic Dayak (Bahasa Dayak) is an Austronesian language spoken by around 1.5 million people in the interior of Borneo, primarily in West Kalimantan (Indonesia) and Sarawak (Malaysia). It belongs to the Malayic branch and includes several dialects such as Ibanic, Kendayan, Maloh, and Kayanic. Despite its large speaker base, it has been largely ignored by global speech recognition providers. This digital gap means Dayak speakers often have to use Indonesian or Malay for voice-based applications, losing the nuance of their mother tongue.

Why Accurate Dayak Speech Recognition Matters

Accurate speech-to-text for Malayic Dayak is not just a technical convenience; it is a tool for cultural preservation. Many Dayak communities still pass down knowledge orally through epic poems, genealogies, and ritual chants. Transcribing these recordings into text creates a permanent, searchable archive. For educators, it means producing reading materials in Dayak for bilingual schools. For content creators, it unlocks subtitling for Dayak-language videos, increasing visibility on platforms like YouTube.

Specific Challenges in Transcribing Dayak

• Limited Training Data: Unlike English or Indonesian, Dayak has very few publicly available transcribed audio datasets. Most ASR models fail because they lack exposure to Dayak phonetics.
• Dialectal Diversity: A speaker from the Iban community may use different vocabulary and intonation than a Kendayan speaker. A one-size-fits-all model would produce errors.
• Phonological Features: Dayak has phonemic vowel length, glottal stops, and consonant clusters that are rare in other regional languages. Standard ASR models often misinterpret these sounds.
• Code-Switching: Many Dayak speakers mix Indonesian or Malay words into their speech, especially for modern concepts. The ASR must handle this seamlessly.

How Speechyou Overcomes These Challenges

Speechyou's Malayic Dayak model is built on a foundation of transfer learning from related Malayic languages, then fine-tuned with a curated corpus of Dayak speech from multiple dialects. Our system:

• Uses dialect-specific acoustic models that users can select from the interface.
• Incorporates a language model that includes common loanwords from Indonesian and Malay.
• Handles background noise and varying recording quality, which is common in field recordings.
• Outputs SRT and VTT subtitle files ready for use.

Use Cases in Practice

• Oral History Projects: NGOs and cultural centers can transcribe hours of elder interviews automatically.
• Podcasts and Radio: Dayak-language broadcasters can provide transcripts for their shows, improving accessibility and SEO.
• Academic Research: Linguists studying Dayak syntax and phonetics can quickly obtain written transcriptions of their recordings.
• Social Media Content: YouTubers creating Dayak-language vlogs can add subtitles to reach a wider audience.
• Government Services: Local administrations in West Kalimantan can transcribe public meetings and announcements for transparency.
