Impact of Acoustic Event Tagging on Scene Classification in a Multi-Task Learning Framework

no code implementations27 Jun 2022 Rahil Parikh, Harshavardhan Sundar, Ming Sun, Chao Wang, Spyros Matsoukas

We conclude that this improvement in ASC performance comes from the regularization effect of using AET and not from the network's improved ability to discern between acoustic events.

An Empirical Analysis on the Vulnerabilities of End-to-End Speech Segregation Models

no code implementations20 Jun 2022 Rahil Parikh, Gaspar Rochette, Carol Espy-Wilson, Shihab Shamma

Knowing that harmonicity is a critical cue for these networks to group sources, in this work, we perform a thorough investigation on ConvTasnet and DPT-Net to analyze how they perform a harmonic analysis of the input mixture.

Canary Extraction in Natural Language Understanding Models

no code implementations ACL 2022 Rahil Parikh, Christophe Dupuy, Rahul Gupta

In this work, we present a version of such an attack by extracting canaries inserted in NLU training data.

Acoustic To Articulatory Speech Inversion Using Multi-Resolution Spectro-Temporal Representations Of Speech Signals

no code implementations11 Mar 2022 Rahil Parikh, Nadee Seneviratne, Ganesh Sivaraman, Shihab Shamma, Carol Espy-Wilson

We used U. of Wisconsin X-ray Microbeam (XRMB) database of clean speech signals to train a feed-forward deep neural network (DNN) to estimate articulatory trajectories of six tract variables.

Harmonicity Plays a Critical Role in DNN Based Versus in Biologically-Inspired Monaural Speech Segregation Systems

no code implementations8 Mar 2022 Rahil Parikh, Ilya Kavalerov, Carol Espy-Wilson, Shihab Shamma

We evaluate their performance with mixtures of natural speech versus slightly manipulated inharmonic speech, where harmonics are slightly frequency jittered.
