Kol Speech to Text: Preserving a Papuan Language with AI

Kol is a Papuan language spoken by around 4,000 people in the East New Britain Province of Papua New Guinea. It is one of the many small languages that make up the region's extraordinary linguistic diversity. Despite its small speaker population, Kol is a vital part of the cultural heritage of the Pomio and Baining communities. The language is primarily oral, with few written resources, making accurate speech-to-text technology a crucial tool for documentation, education, and modern communication.

Why Accurate Transcription Matters for Kol

For many small languages, the risk of losing knowledge is high. Kol speakers are increasingly using English and Tok Pisin in daily life, and younger generations may not be fluent in their ancestral language. Transcribing oral stories, songs, and conversations into written form helps preserve the language for future learners. It also enables the creation of bilingual materials that support literacy in both Kol and the national languages. Accurate transcription is the first step in building a digital presence for Kol, allowing speakers to generate subtitles for videos, produce written records of events, and maintain their linguistic identity.

Transcription Challenges Specific to Kol

Kol presents several challenges for automatic speech recognition:

• Limited training data: There are very few transcribed Kol audio samples available, making it hard for standard ASR models to learn the language's patterns.
• Prenasalized stops: Kol uses sounds like /mb/ and /nd/ that are uncommon in many languages, requiring specialized acoustic modeling.
• Vowel harmony: The language exhibits vowel harmony that can affect word boundaries and pronunciation, which generic models often misinterpret.
• Lack of standard orthography: Kol is mostly oral, so speakers may write the same word differently. Speechyou provides a consistent Latin-based transcription that users can edit to match their preference.

Speechyou's AI is designed to handle these challenges. By using transfer learning from related languages and incorporating user corrections, the model continuously improves its accuracy for Kol. The system also adapts to varying audio quality, which is common in field recordings made with portable devices.

Use Cases for Kol Transcription

Kol transcription can serve many practical purposes:

• Oral history preservation: Elders can record stories and have them automatically transcribed, creating a written archive that can be studied and shared.
• Community media: Local radio stations and YouTube channels that broadcast in Kol can generate subtitles, making their content accessible to a wider audience.
• Education: Teachers can transcribe lessons and create bilingual reading materials to help children learn both Kol and English.
• Language documentation: Linguists and anthropologists can transcribe interviews and word lists quickly, speeding up the creation of dictionaries and grammars.
• Church and religious use: Sermons and hymns in Kol can be transcribed for distribution to congregations.
• Research: Academics studying Papua New Guinea's languages can use Kol transcription to analyze speech patterns and compare with other languages.
