While biometric authentication has advanced significantly in recent years, evidence shows
the technology can be susceptible to malicious spoofing attacks. The research community …

A speaker verification system automatically accepts or rejects a claimed identity of a speaker
based on a speech sample. Recently, a major progress was made in speaker verification …

In recent years, automatic speaker verification (ASV) is used extensively for voice biometrics.
This leads to an increased interest to secure these voice biometric systems for real-world …

Voice conversion-the methodology of automatically converting one's utterances to sound as
if spoken by another speaker-presents a threat for applications relying on speaker …

This paper re-examines the threat of spoofing or presentation attacks in the context of
automatic speaker verification (ASV). While voice conversion and speech synthesis attacks …

The vulnerability of automatic speaker verification systems to spoofing is now well accepted.
While recent work has shown the potential to develop countermeasures capable of detecting …

Voice conversion technique, which modifies one speaker's (source) voice to sound like
another speaker (target), presents a threat to automatic speaker verification. In this paper …

This paper presents a new countermeasure for the protection of automatic speaker
verification systems from spoofed, converted voice signals. The new countermeasure …

We study the scenario where individuals (speakers) contribute to the publication of an
anonymized speech corpus. Data users leverage this public corpus for downstream tasks …

This paper analyses the threat of replay spoofing or presentation attacks in the context of
automatic speaker verification. As relatively high‐technology attacks, speech synthesis and …
