A pair of Israeli health tech companies, Beyond Verbal and Healthymize, plan to merge to form Newton, Mass.-based Vocalis Health. The company will be focused on developing vocal biomarkers, which track voice patterns via phone calls or smart devices to screen for various voice-indicating ailments including chronic respiratory and cardiac conditions, as well as depression. Vocalis has raised a $9 million financing led by Israeli health tech and life science venture firm Amoon to accumulate additional clinical data and enhance its voice database.
