Closing the Speech-Text Gap with Limited Audio for Effective Domain Adaptation in LLM-Based ASR

Thibault Bañeras-Roux, Sergio Burdisso, Esaú Villatoro-Tello +9

Conventional end-to-end automatic speech recognition (ASR) systems rely on paired speech-text data for domain adaptation. Recent LLM-based ASR architectures connect a speech encode…

Distilling Conversations: Abstract Compression of Conversational Audio Context for LLM-based ASR

Shashi Kumar, Esaú Villatoro-Tello, Sergio Burdisso +7

Standard LLM-based speech recognition systems typically process utterances in isolation, limiting their ability to leverage conversational context. In this work, we study whether m…

Nonparametric Variational Differential Privacy via Embedding Parameter Clipping

Dina El Zein, Shashi Kumar, James Henderson

The nonparametric variational information bottleneck (NVIB) provides the foundation for nonparametric variational differential privacy (NVDP), a framework for building privacy-pres…

Doctor or Patient? Synergizing Diarization and ASR for Code-Switched Hinglish Medical Conditions Extraction

Séverin Baroudi, Yanis Labrak, Shashi Kumar +7

Extracting patient medical conditions from code-switched clinical spoken dialogues is challenging due to rapid turn-taking and highly overlapped speech. We present a robust system…

Text-only adaptation in LLM-based ASR through text denoising

Andrés Carofilis, Sergio Burdisso, Esaú Villatoro-Tello +8

Adapting large language model (LLM)-based automatic speech recognition (ASR) systems to new domains using text-only data is a significant yet underexplored challenge. Standard fine…

Latent Space Factorization in LoRA

Shashi Kumar, Yacouba Kaloga, John Mitros +2

Low-rank adaptation (LoRA) is a widely used method for parameter-efficient finetuning. However, existing LoRA variants lack mechanisms to explicitly disambiguate task-relevant info…
