Before the Mic: Physical-Layer Voiceprint Anonymization with Acoustic Metamaterials
EchoMask employs reconfigurable acoustic metamaterials to generate physical-layer frequency-selective interference that raises voiceprint miss-match rates above 90% across tested microphones while preserving speech intelligibility.
