Kuot Speech to Text: Preserving a Unique Language with AI

The Kuot language, spoken in several villages along the east coast of New Ireland, Papua New Guinea, is a rare linguistic treasure. As a language isolate, it shares no proven genetic relationship with any other language, making its documentation a priority for linguists. However, with only around 2,400 native speakers and most of them bilingual in Tok Pisin, Kuot is considered endangered. Accurate speech-to-text technology can support revitalization by making it easier to create written materials, subtitles, and educational content.

Why Kuot Transcription Matters

Transcribing Kuot audio is not just about converting sound to text; it is about capturing the full phonological richness of the language. The three tones (high, mid, low) are phonemic and must be represented in transcription. Moreover, the bilabial trill /ʙ/ is a sound that occurs in very few languages worldwide. Without specialized ASR models, these features are lost. Speechyou's Kuot model is trained on fieldwork recordings that include explicit tone and trill labels.

Transcription Challenges Specific to Kuot

• Tonal Recognition: Most ASR engines treat tone as irrelevant. Speechyou uses a pitch-tracker and tone classifier integrated into the acoustic model.
• Limited Data: Only about 5 hours of transcribed Kuot audio exist publicly. The model uses transfer learning from tonal languages and synthetic data generation.
• Nasal Vowels: Kuot has nasalized vowels (ã, ẽ, etc.) that can overlap with oral vowels. Acoustic features such as the relative energy in the nasal formant are used.
• Dialectal Variation: The three main dialect groups differ in vowel quality and intonation. The model is trained on Central Kuot but can adapt to other variants with minimal additional data.

Use Cases for Kuot Speech-to-Text

• Community Language Archives: Record and transcribe oral histories, stories, and songs for future generations.
• Education: Create subtitled videos for literacy classes where children match spoken Kuot to written words.
• Bible Translation: Speed up the process of creating written scriptures in Kuot by transcribing recordings of translators.
• Linguistic Research: Allow researchers to quickly obtain time-aligned transcriptions of field recordings for grammatical analysis.
• Healthcare: Broadcast health messages in Kuot and provide written summaries for community health workers.
• Podcasting: Kuot content creators can generate subtitles to reach a wider audience, including hearing-impaired community members.

How Speechyou Helps

Speechyou offers a dedicated Kuot language model that is accessible through a simple web interface. You can upload audio or video files and receive SRT and VTT subtitle files in return. The system preserves tone marks using Unicode combining characters and clearly indicates the bilabial trill with the proper IPA character (ʙ). For users who need higher accuracy on specific vocabulary, the custom boost feature allows uploading a list of words. The service is included in the Solo plan with unlimited transcription, making it affordable for community projects.

Getting Started

Using Speechyou for Kuot is straightforward. Select 'Kuot' from the language list, upload your file, and wait for processing. The model works best with clear, slow speech and minimal overlap. For noisy recordings, we recommend using a directional microphone or our noise reduction preprocessing. Once the transcription is ready, you can edit the text in the online editor before exporting the subtitle file.

We are committed to supporting endangered languages like Kuot. If you have additional recordings that can improve our model, please contact us. Together, we can ensure that the voices of Kuot speakers are preserved in text.
