Voinosis, a South Korean startup developing AI to detect changes in brain health through voice analysis, won a competition at DETO 2026 in Seoul this week for a spot in TechCrunch Disrupt 2027’s Startup Battlefield 200, according to TechCrunch.
The company’s AI tool analyzes speech patterns including pitch, pauses, rhythm and response times to detect changes linked to brain health. Each voice check takes less than five minutes. Voinosis says its technology has been tested in Greek, Japanese and English without requiring separate training for each language.
In a clinical study involving 146 participants, the startup claims its technology achieved 88% accuracy in screening for potential cognitive issues. The company targets hospitals, senior living facilities, insurers and individual consumers, and plans to link voice checks with cognitive training, assessments and treatment provided by healthcare professionals.
Voinosis was founded by Grace Shin, who spent more than 25 years as an otologic surgeon. The startup is currently raising a Series A round and has secured a South Korean pharmaceutical company as a strategic investor.
Eight other early-stage South Korean startups competed at the event, working across healthcare, fintech, energy, semiconductors and AI. All nine startups are looking to enter the U.S. market as part of broader international expansion plans.
Among the other competitors, Awesome Lab makes ThermoFlux, a heating system that uses water electrolysis and ionization to generate heat for buildings, water supply and industrial processes. The company plans to supply core OEM modules in the U.S. and work with boiler, water heater and HVAC companies on product development.
