SpeechGuard: Exploring the Adversarial Robustness of Multimodal Large Language Models

no code implementations14 May 2024 Raghuveer Peri, Sai Muralidhar Jayanthi, Srikanth Ronanki, Anshu Bhatia, Karel Mundnich, Saket Dingliwal, Nilaksh Das, Zejiang Hou, Goeric Huybrechts, Srikanth Vishnubhotla, Daniel Garcia-Romero, Sundararajan Srinivasan, Kyu J Han, Katrin Kirchhoff

Despite safety guardrails, experiments on jailbreaking demonstrate the vulnerability of SLMs to adversarial perturbations and transfer attacks, with average attack success rates of 90% and 10% respectively when evaluated on a dataset of carefully designed harmful questions spanning 12 different toxic categories.

SpeechVerse: A Large-scale Generalizable Audio Language Model

no code implementations14 May 2024 Nilaksh Das, Saket Dingliwal, Srikanth Ronanki, Rohit Paturi, David Huang, Prashant Mathur, Jie Yuan, Dhanush Bekal, Xing Niu, Sai Muralidhar Jayanthi, Xilai Li, Karel Mundnich, Monica Sunkara, Sundararajan Srinivasan, Kyu J Han, Katrin Kirchhoff

The models are instruction finetuned using continuous latent representations extracted from the speech foundation model to achieve optimal zero-shot performance on a diverse range of speech processing tasks using natural language instructions.

End-to-End Single-Channel Speaker-Turn Aware Conversational Speech Translation

1 code implementation1 Nov 2023 Juan Zuluaga-Gomez, Zhaocheng Huang, Xing Niu, Rohit Paturi, Sundararajan Srinivasan, Prashant Mathur, Brian Thompson, Marcello Federico

Conventional speech-to-text translation (ST) systems are trained on single-speaker utterances, and they may not generalize to real-life scenarios where the audio contains conversations by multiple speakers.

Speaker Diarization of Scripted Audiovisual Content

no code implementations4 Aug 2023 Yogesh Virkar, Brian Thompson, Rohit Paturi, Sundararajan Srinivasan, Marcello Federico

The media localization industry usually requires a verbatim script of the final film or TV production in order to create subtitles or dubbing scripts in a foreign language.

Device Directedness with Contextual Cues for Spoken Dialog Systems

no code implementations23 Nov 2022 Dhanush Bekal, Sundararajan Srinivasan, Sravan Bodapati, Srikanth Ronanki, Katrin Kirchhoff

In this work, we define barge-in verification as a supervised learning task where audio-only information is used to classify user spoken dialogue into true and false barge-ins.

Representation learning through cross-modal conditional teacher-student training for speech emotion recognition

no code implementations30 Nov 2021 Sundararajan Srinivasan, Zhaocheng Huang, Katrin Kirchhoff

To improve the efficacy of our approach, we propose a novel estimate of the quality of the emotion predictions, to condition teacher-student training.

Speaker-conversation factorial designs for diarization error analysis

no code implementations10 Jun 2021 Scott Seyfarth, Sundararajan Srinivasan, Katrin Kirchhoff

Determining the cause of diarization errors is difficult because speaker voice acoustics and conversation structure co-vary, and the interactions between acoustics, conversational structure, and diarization accuracy are complex.
