We have a large client/customer in Illinois who has decided against using our voice sdk in their iOS/Android app because of the fear of getting sued for BIPA violation. It's not that they think we're creating voice prints without consent, it's just that their legal team has warned them that if they get sued, it could be very costly to defend. We even changed our privacy policy to note that "biometrics" are not obtained, and even went to on-device speech recognition apis provided by Google and Apple.
