Walmart's AI Voice System Allegedly Collected Illinois Callers' Biometric Voiceprints Without Consent

A proposed class action alleges that Walmart's AI voice system captured biometric voiceprints from Illinois residents who called local stores without first obtaining meaningful consent or explaining how the biometric data would be retained and deleted. Plaintiff Amber Smith said the system captured her voiceprint during two calls in December 2025 and one in July 2026.
