Towards Audio Token Compression in Large Audio Language Models

Saurabhchand Bhati, Samuel Thomas, Hilde Kuehne +2

Large Audio Language Models (LALMs) deliver strong performance across speech and audio tasks, but their audio encoders generate high-rate token sequences (e.g., 25 tokens/s), makin…

Towards Unsupervised Speech Recognition at the Syllable-Level

Liming Wang, Junrui Ni, Kai-Wei Chang +4

Training speech recognizers with unpaired speech and text -- known as unsupervised speech recognition (UASR) -- is a crucial step toward extending ASR to low-resource languages in…

Recognizing Dementia from Neuropsychological Tests with State Space Models

Liming Wang, Saurabhchand Bhati, Cody Karjadi +2

Early detection of dementia is critical for timely medical intervention and improved patient outcomes. Neuropsychological tests are widely used for cognitive assessment but have tr…

USAD: Universal Speech and Audio Representation via Distillation

Heng-Jui Chang, Saurabhchand Bhati, James Glass +1

Self-supervised learning (SSL) has revolutionized audio representations, yet models often remain domain-specific, focusing on either speech or non-speech tasks. In this work, we pr…

Omni-R1: Do You Really Need Audio to Fine-Tune Your Audio LLM?

Andrew Rouditchenko, Saurabhchand Bhati, Edson Araujo +4

We propose Omni-R1 which fine-tunes a recent multi-modal LLM, Qwen2.5-Omni, on an audio question answering dataset with the reinforcement learning method GRPO. This leads to new St…
