Ledo Kaili: Preserving a Sulawesi Language with AI Speech-to-Text

Ledo Kaili, or Basa Ledo, is a vibrant Austronesian language spoken by around 350,000 people in Central Sulawesi, Indonesia. It is the mother tongue of many communities in the districts of Palu, Sigi, Donggala, and Parigi Moutong. Despite its relatively large speaker base, Ledo Kaili is underrepresented in digital technology. There are few online resources, and automated transcription tools have largely ignored it. This is where Speechyou steps in, offering the first dedicated AI speech-to-text service for Ledo Kaili.

Why Accurate Speech-to-Text for Ledo Kaili Matters

Oral traditions are central to Ledo Kaili culture. Stories, songs, and rituals are passed down verbally, but they risk being lost as younger generations shift to Indonesian. Transcribing these recordings creates a permanent, searchable archive. Additionally, local media outlets produce news and entertainment in Basa Ledo, but subtitling remains manual and slow. Automated transcription accelerates this process, making content more accessible to both native speakers and learners. For researchers, having transcripts of interviews allows for efficient analysis and documentation of the language.

Transcription Challenges in Ledo Kaili

Ledo Kaili presents several challenges for automatic speech recognition:

• Limited training data: Unlike English or Indonesian, there are few publicly available speech corpora for Ledo Kaili. Speechyou overcomes this by using a multilingual model pre-trained on related languages and fine-tuned with a specialized dataset.
• Dialectal variation: The four main dialects (Da'a, Lindu, Palu, Sigi) differ in phonetics and lexicon. For instance, the Palu dialect has a more reduced vowel system, while Da'a retains final consonants. Speechyou's model is trained to recognize all major variants.
• Code-switching: Many Ledo Kaili speakers frequently mix Indonesian into their speech, especially in urban settings. The Speechyou model can detect and separate both languages, providing clean bilingual transcripts.
• Phonemic glottal stop: The glottal stop (often written with an apostrophe) is common in Ledo Kaili and must be accurately transcribed. The speech recognition system is trained to capture this feature.
