Uncovering Audio-Text Alignment in Large Audio-Language Models through Cross-Modal Concept Neurons

Read the original on arXiv Computation and Language →

The paper investigates how large audio‑language models (LALMs) integrate audio and text representations. By identifying cross‑modal neurons that encode both modalities, the authors demonstrate that audio and text representations align within a shared subspace across three LALMs and four acoustic attribute types. Causal interventions on these neurons confirm their necessity for prediction and show they can be manipulated to steer model outputs.

Heard but Not Heeded: Paralinguistic Information Encoding and Loss in Audio-Language Models

The paper investigates whether audio‑language models capture paralinguistic cues beyond spoken content. Using the Expresso dataset and four open‑source models, the authors trace how speaking style information is encoded in the late layers of the audio encoder but is degraded before reaching the final output. They find that some models are content‑driven while others are acoustic‑driven, revealing a gap between what is encoded and what is utilized in current audio‑language models.

BAT-CLIP: Trimodal Alignment of Brain, Audio and Text

BAT-CLIP is a trimodal alignment framework that jointly aligns intracranial EEG (iEEG) neural embeddings to both pretrained audio and text anchors within a shared, frozen audio‑text manifold. Unlike existing CLIP‑style brain‑speech models that anchor neural activity to a single modality, BAT‑CLIP leverages both audio and text to preserve temporal structure and linguistic separability. On the naturalistic Podcast benchmark, BAT‑CLIP produces more robust representations than bimodal CLIP baselines and demonstrates the value of self‑supervised foundation models for CLIP training.
