Spoofing detection under noisy conditions: a preliminary investigation and an initial database

2016 · arXiv (Cornell University)

Spoofing detection for automatic speaker verification (ASV), which is to discriminate between live speech and attacks, has received increasing attentions recently. However, all the previous studies have been done on the clean data without significant …

A Modularized Neural Network with Language-Specific Output Layers for Cross-lingual Voice Conversion

2019 · arXiv (Cornell University)

This paper presents a cross-lingual voice conversion framework that adopts a modularized neural network. The modularized neural network has a common input structure that is shared for both languages, and two separate output modules, one …

Improving Non-native Word-level Pronunciation Scoring with Phone-level Mixup Data Augmentation and Multi-source Information

2022 · arXiv (Cornell University)

Deep learning-based pronunciation scoring models highly rely on the availability of the annotated non-native data, which is costly and has scalability issues. To deal with the data scarcity problem, data augmentation is commonly used for …
