Our Journey


Seeing the Future

Working with verbal signal processing technologies during his early studies, Dirk discovered the potential of Vocal Biomarkers to detect and monitor diseases. Back in the days, voice and speech samples were recorded under laboratory conditions using sophisticated microphones and costly high-performance computers.
