Few-Shot Calibration for Sim-to-Real Single-Channel Speaker Distance Estimation
Michael Neri, Archontis Politis, Tuomas Virtanen
Speaker distance estimators are trained almost exclusively on simulated room acoustics, because real recordings annotated with the true talker-to-microphone distance are scarce. We…
Domain-Incremental Learning for Multi-Channel Replay Speech Detection
Michael Neri
Replay attacks are the most accessible threat to voice-controlled systems, and the acoustic cues that expose them are strongly modulated by the environment in which the attack is m…
Dependence on Early and Late Reverberation of Single-Channel Speaker Distance Estimation
Michael Neri, Archontis Politis, Tuomas Virtanen
Single-channel speaker distance estimation has recently achieved centimeter-level accuracy in simulated environments, yet it remains unclear which components of the room impulse re…
Multi-Channel Replay Speech Detection using Acoustic Maps
Michael Neri, Tuomas Virtanen
Replay attacks remain a critical vulnerability for automatic speaker verification systems, particularly in real-time voice assistant applications. In this work, we propose acoustic…
Acoustic Simulation Framework for Multi-channel Replay Speech Detection
Michael Neri, Tuomas Virtanen
Replay speech attacks pose a significant threat to voice-controlled systems, especially in smart environments where voice assistants are widely deployed. While multi-channel audio…
Impact of Microphone Array Mismatches to Learning-based Replay Speech Detection
Michael Neri, Tuomas Virtanen
In this work, we investigate the generalization of a multi-channel learning-based replay speech detector, which employs adaptive beamforming and detection, across different microph…
Multi-channel Replay Speech Detection using an Adaptive Learnable Beamformer
Michael Neri, Tuomas Virtanen
Replay attacks belong to the class of severe threats against voice-controlled systems, exploiting the easy accessibility of speech signals by recorded and replayed speech to grant…
