Praykinson turned elderly Thais' daily prayer into voice therapy

Parkinson's disease progressively steals the voice, and speech or singing exercises are the standard therapy to slow that loss. But for Thailand's elderly patients the prescription didn't fit: singing is not embedded in their everyday routine, so the exercises felt foreign, were hard to practice alone at home, and were quietly abandoned — the exact adherence gap that lets the disease's stranglehold on speech advance.

The obvious fix is to make the existing singing-based therapy more accessible or more motivating — better apps, gamified scores, hospital-led group sessions. All of it still asks an elderly Thai to adopt a practice (singing) that isn't part of the life they already lead, and that is precisely the barrier that made the therapy fail in the first place.

Dentsu Thailand and Vajira Hospital built Praykinson, a karaoke-style app in which the 'song' the patient performs is a familiar prayer. With 75.9% of Thais praying daily, the app turns an act patients already perform into a structured voice exercise: it shows the prayer text with colour-coded cues for rhythm and pace, an on-screen EQ bar feeds back vocal control, and each session ends in a progress score — alongside daily reminders that hook therapy onto a routine that already exists.
