Spoken across the Visayas and Mindanao, and the language most often missing from commercial models.
What Cebuano supports today
Understanding and reply in written conversation — the floor every language here has.
Speech-to-text and text-to-speech for recorded voice notes, processed in batch, not live.
Live, real-time speech on a voice call — not yet built for any language.
Measured against published targets
Measured performance of the deployed ASR and TTS models for Cebuano, against Proto's target thresholds. Proto publishes these figures whether or not they clear the target.
Mean opinion score rates the naturalness of synthesised speech on a 1–5 scale. Tests ran on an Azure Standard NC4as T4 v3 instance with an NVIDIA Tesla T4 GPU; the ASR test set used audio samples of 5–10 seconds.
Where Cebuano is deployed
Cebuano is used for regional citizen support in the Visayas and Mindanao, where callers routinely code-switch between Cebuano, Tagalog and English within a single conversation.
Henry answers patient enquiries about services, doctors and diagnostic results in Tagalog, Cebuano and English, in text and voice, drawing on a live medical directory rather than manually maintained content — now handling 93% of enquiries automatically across more than ten locations spanning Metro Manila, Calabarzon and the Visayas, with the rest escalated to the client's own contact centre.
