End-to-end speech synthesis is a promising approach that directly converts raw text to
speech. Although it was shown that Tacotron2 outperforms classical pipeline systems with …

To secure automatic speaker verification (ASV) systems from intruders, robust
countermeasures for spoofing attack detection are required. The ASVspoof series of …

The rise in demand of voice biometric systems also increases the threat from various kinds
of spoofing attacks from unauthorized users. The latest ASVspoof 2021 challenge devotes to …

Gas-insulated switchgears (GISs) are an essential component of the power system, but in
the event of a failure they may pose a serious threat to the safe operation of the entire power …

Over the past few years, significant progress has been made in the field of presentation
attack detection (PAD) for automatic speaker recognition (ASV). This includes the …

From speech to images, and videos, advances in machine learning have led to dramatic
improvements in the quality and realism of so-called AI-synthesized content. While there are …

Speech data conveys sensitive speaker attributes like identity or accent. With a small
amount of found data, such attributes can be inferred and exploited for malicious purposes …

This paper presents a cross-lingual voice conversion approach using bilingual Phonetic
PosteriorGram (PPG) and average modeling. The proposed approach makes use of …

We introduce a novel speech synthesis system, called NAUTILUS, that can generate speech
with a target voice either from a text input or a reference utterance of an arbitrary source …

Synthesising spontaneous speech is a difficult task due to disfluencies, high variability and
syntactic conventions different from those of written language. Using found data, as opposed …
