Replay Spoofing Detection System for Automatic Speaker Verification Using Multi-Task Learning of Noise Classes

2018

In this paper, we propose a replay attack spoofing detection system for automatic speaker verification using multi-task learning of noise classes. We define the noise that is caused by the replay attack as replay noise. …

Curriculum learning for self-supervised speaker verification

2022 · arXiv (Cornell University)

The goal of this paper is to train effective self-supervised speaker representations without identity labels. We propose two curriculum learning strategies within a self-supervised learning framework. The first strategy aims to gradually increase the number …

Chain-of-Thought Training for Open E2E Spoken Dialogue Systems

2025 · arXiv (Cornell University)

Unlike traditional cascaded pipelines, end-to-end (E2E) spoken dialogue systems preserve full differentiability and capture non-phonemic information, making them well-suited for modeling spoken interactions. However, existing E2E approaches often require large-scale training data and generates responses …
