Significance of Data Augmentation for Improving Cleft Lip and Palate Speech Recognition
Protima Nomo Sudro, Rohan Kumar Das, Rohit Sinha +1
The automatic recognition of pathological speech, particularly from children with any articulatory impairment, is a challenging task due to various reasons. The lack of available d…
Self-supervised Speaker Recognition with Loss-gated Learning
Ruijie Tao, Kong Aik Lee, Rohan Kumar Das +2
In self-supervised learning for speaker recognition, pseudo labels are useful as the supervision signals. It is a known fact that a speaker recognition model doesn't always benefit…
Graph Fourier Transform based Audio Zero-watermarking
Longting Xu, Daiyu Huang, Syed Faham Ali Zaidi +2
The frequent exchange of multimedia information in the present era projects an increasing demand for copyright protection. In this work, we propose a novel audio zero-watermarking…
Is Someone Speaking? Exploring Long-term Temporal Features for Audio-visual Active Speaker Detection
Ruijie Tao, Zexu Pan, Rohan Kumar Das +3
Active speaker detection (ASD) seeks to detect who is speaking in a visual scene of one or more speakers. The successful ASD depends on accurate interpretation of short-term and lo…
Data Augmentation with Signal Companding for Detection of Logical Access Attacks
Rohan Kumar Das, Jichen Yang, Haizhou Li
The recent advances in voice conversion (VC) and text-to-speech (TTS) make it possible to produce natural sounding speech that poses threat to automatic speaker verification (ASV)…
