Bauro Speech to Text: Preserving a Language of Makira Island

Bauro is an Oceanic language spoken by around 5,000 people on Makira (San Cristobal) Island in the Solomon Islands. It is part of the Southeast Solomonic family and is closely related to neighboring languages like Arosi. Despite its small number of speakers, Bauro has a rich oral tradition and is used in daily life, church, and community events. However, like many minority languages, it faces pressure from English and Solomon Islands Pijin.

Accurate speech-to-text for Bauro is not just a technical achievement; it is a tool for language preservation and cultural continuity. Transcribing audio in Bauro allows communities to document stories, songs, and knowledge that have been passed down orally for generations. It also enables the creation of subtitles for video content, making media accessible to deaf community members and learners.

Key Challenges in Bauro Speech Recognition

Developing automatic speech recognition (ASR) for Bauro comes with unique hurdles:

• Phonetic complexity: Bauro has prenasalized stops such as /mb/ and /nd/, which are rare in world languages and easily confused with plain nasals by standard ASR systems.
• Limited data: With fewer than 10,000 speakers, there is very little transcribed audio available for training. Most existing datasets are from linguistic fieldwork and are not publicly accessible.
• Dialect diversity: Three main dialects — Haununu in the north, Ravenga in the south, and central Bauro — differ in pronunciation, vocabulary, and intonation. A one-size-fits-all model would perform poorly.

Speechyou addresses these challenges through dedicated models trained on community-contributed recordings and field data. The system allows users to select their dialect before transcription, and the acoustic model has been fine-tuned to recognize prenasalized stops and other distinctive sounds.

Why Bauro Transcription Matters

The ability to convert Bauro speech into text has practical applications across many domains:

• Oral history preservation: Elders can record traditional stories and have them transcribed for archives and future generations.
• Church and community: Sermons and announcements can be transcribed and shared with those who cannot attend services.
• Education: Schools can create subtitled videos in Bauro to support bilingual education and literacy.
• Media accessibility: Community radio stations can subtitle their programs, reaching deaf listeners.
• Language documentation: Linguists can quickly search and analyze transcribed recordings for research.
