Through our research we continue to answer new questions about the nature of the infant cry, while also designing and developing efficient signal-processing and machine-learning algorithms for analysis.

Clinical Study

Our clinical studies with partners in Nigeria and Canada are aimed at acquiring a large database of clinically-annotated infant cries and further validating the Ubenwa algorithm in a real setting. Our goal is to acquire up to 10,000 cries from 2,500 patients within 2 years. This will ensure that we have the right amount and diversity of data to demonstrate the efficacy of Ubenwa.
