New framework enhances speech anonymization while preserving data utility

Researchers have developed a new two-stage framework for speech anonymization that aims to preserve both linguistic content and acoustic identity while maintaining data utility. This framework uses a generative speech editing model to replace personally identifiable information and a novel flow-matching-based approach called F3-VA to create diverse anonymized speakers. The proposed evaluation protocol assesses privacy using speaker verification metrics and utility by training downstream models for Automatic Speech Recognition, Text-to-Speech, and Speech Emotion Recognition from scratch, showing improved privacy with minimal utility loss compared to existing methods.
