AccentCL: Robust Accent Classification with Incremental Expansion

Mu-Ruei Tseng, Waris Quamer, Ghady Nasrallah +1

Accent classifiers are typically trained with a fixed label inventory and cannot accommodate new accent categories as new data becomes available. Moreover, accented speech corpora…

VOSSA: Voiceprint Optimization for Streaming Speech Architectures

Mu-Ruei Tseng, Waris Quamer, Ghady Nasrallah +1

Real-time voice conversion (VC) systems commonly rely on pretrained speaker embeddings from automatic speaker verification (ASV) models. While effective for speaker discrimination,…

PHONOS: PHOnetic Neutralization for Online Streaming Applications

Waris Quamer, Mu-Ruei Tseng, Ghady Nasrallah +1

Speaker anonymization (SA) systems modify timbre while leaving regional or non-native accent cues intact, which is problematic because such cues can reveal a speaker's first-langua…

TVTSyn: Content-Synchronous Time-Varying Timbre for Streaming Voice Conversion and Anonymization

Waris Quamer, Mu-Ruei Tseng, Ghady Nasrallah +1

Real-time voice conversion and speaker anonymization require causal, low-latency synthesis without sacrificing intelligibility or naturalness. Current systems have a core represent…

DarkStream: real-time speech anonymization with low latency

Waris Quamer, Ricardo Gutierrez-Osuna

We propose DarkStream, a streaming speech synthesis model for real-time speaker anonymization. To improve content encoding under strict latency constraints, DarkStream combines a c…

Disentangling segmental and prosodic factors to non-native speech comprehensibility

Waris Quamer, Ricardo Gutierrez-Osuna

Current accent conversion (AC) systems do not disentangle the two main sources of non-native accent: segmental and prosodic characteristics. Being able to manipulate a non-native s…

End-to-end streaming model for low-latency speech anonymization

Waris Quamer, Ricardo Gutierrez-Osuna

Speaker anonymization aims to conceal cues to speaker identity while preserving linguistic content. Current machine learning based approaches require substantial computational reso…
