Speech Pseudonymisation Assessment Using Voice Similarity Matrices

Understand

The proliferation of speech technologies and rising privacy legislation calls for the development of privacy preservation solutions for speech applications.

• These are essential since speech signals convey a wealth of rich, personal and potentially sensitive information.
• Anonymisation, the focus of the recent VoicePrivacy initiative, is one strategy to protect speaker identity information.
• Pseudonymisation solutions aim not only to mask the speaker identity and preserve the linguistic content, quality and naturalness, as is the goal of anonymisation, but also to preserve voice distinctiveness.
