The Kalagan Language and the Need for AI Speech-to-Text

Kalagan (also known as Kagan) is a Malayo-Polynesian language spoken by around 100,000 people in the southern Philippines, primarily in the provinces of Davao del Sur, Davao Oriental, Sarangani, and Compostela Valley. It belongs to the Danao subgroup of the Austronesian family, closely related to Tagalog, Cebuano, and Maranao. The language is written in the Latin script, with an orthography similar to Filipino. Despite its relatively small speaker population, Kalagan has a vibrant oral culture, including epic poems, folk tales, and songs. However, like many minority languages, it faces pressures from larger languages such as Cebuano and Filipino, leading to language shift among younger generations.

Why Accurate Kalagan Speech-to-Text Matters

Digital tools for transcription and subtitling can play a crucial role in language preservation and revitalization. By converting spoken Kalagan into written text, communities can create archives of oral history, produce educational materials, and make their culture accessible to a global audience. Yet, most mainstream speech-to-text services do not support Kalagan. This is where Speechyou steps in, offering a dedicated AI model trained to understand the unique sounds and grammar of the language.

Specific Transcription Challenges

Transcribing Kalagan comes with its own set of hurdles:

• Phonemic vowel length: Kalagan distinguishes between short and long vowels, which can change meaning (e.g., bata 'child' vs. bataa 'to carry'). Our model captures these subtle differences.
• Glottal stops: The glottal stop is a consonant in Kalagan, often appearing between vowels or at word endings. Standard ASR systems may miss it, but Speechyou's acoustic model is trained to recognize it.
• Dialectal variation: Western Kalagan, Eastern Kalagan, and the Kagan dialect have lexical and phonological differences. Speechyou's model is trained on data from multiple dialects to ensure broad coverage.
• Code-switching: Many Kalagan speakers mix Filipino and English in daily conversation. Speechyou's multilingual capabilities allow it to transcribe mixed-language audio accurately.

Use Cases for Kalagan Transcription
