Urak Lawoi' Speech-to-Text: Preserving a Sea Gypsy Language with AI

The Urak Lawoi' language (Thai: อูรักลาโวย) is spoken by a small community of sea nomads living along the Andaman coast of Thailand and on islands such as Phuket, Ko Phi Phi, and the Adang archipelago. With an estimated speaker population of around 3,000 to 5,000, it is classified as endangered by UNESCO. The language belongs to the Malayic subgroup of the Austronesian family, closely related to Malay and Indonesian. Traditionally, Urak Lawoi' has no written literature; however, in recent decades, speakers and linguists have adopted the Thai script for writing. This development opens new possibilities for digital preservation, but also introduces specific challenges for automatic speech recognition.

Why Accurate Speech-to-Text Matters for Urak Lawoi'

For a minority language like Urak Lawoi', speech-to-text technology can be a lifeline. Transcribe Urak Lawoi' audio from oral histories, folk tales, and everyday conversations to create a permanent written record. Accurate transcription enables the community to produce subtitles for videos, make content accessible to younger generations who may be more comfortable reading Thai, and support language revitalization programs. Moreover, researchers can use transcripts for linguistic analysis, while tourism operators can add Urak Lawoi' signage and promotional materials to celebrate local culture.

Transcription Challenges Specific to Urak Lawoi'

The main challenges for an Urak Lawoi' speech-to-text system include:

• Non-tonal phonology in a tonal script: Thai script relies on tone marks, but Urak Lawoi' is not tonal. Our model ignores tone markers when they are absent in speech, outputting a phonetic spelling that matches the spoken form.
• Lack of standardized orthography: Different writers may spell the same word differently (e.g., /ikan/ for 'fish' can be ikan หรือ อีแกน). Speechyou learns common variations from training data.
• Small dataset: Most commercial ASR systems skip Urak Lawoi' because there is little labeled audio. Speechyou's dedicated collection effort has produced a robust training corpus covering both major dialects.
• Background noise from sea and wind: Many recordings are made outdoors near the coast. Speechyou's noise-robust models are trained on similar environments.

Use Cases for Urak Lawoi' Transcription

Urak Lawoi' speech-to-text serves multiple purposes:

1. Cultural Archives: Transcribe storytelling sessions from elders and create searchable digital libraries.
2. Educational Materials: Produce transcripts for bilingual textbooks that teach Urak Lawoi' to children.
3. Media Subtitling: Add Urak Lawoi' subtitles to documentaries and YouTube videos about the community.
4. Tourism: Generate Thai translations from Urak Lawoi' audio to improve communication with visitors.
5. Community Radio: Create written records of radio broadcasts for later reference.
6. Academic Research: Provide linguists with aligned transcripts for phonetic and grammatical analysis.
