STAM-ASR: Speaker-Temporal Anchoring with Memory for Multi-Speaker ASR

Natural conversations make both speech recognition and speaker attribution challenging for ASR, as speakers take turns, overlap, and reappear over time. We propose STAM-ASR, Speaker-Temporal Anchoring with Memory, a lightweight framework that extends an already pretrained AudioLLM for multi-speaker ASR. Without relying...

The Alignment Gap: A Benchmark Demonstrating the Lack of Cross-Lingual Mapping in Dialect-Specialized Language Models - The Case of Ehugbo

This work introduces the first information retrieval benchmark resource for Ehugbo, a high-quality parallel multimodal corpus constructed from a high-quality parallel multimodal corpus that reveals the ''Alignment Gap'', where African-centric foundation models that excel at linguistic familiarity with Igbo achieve <5%...

TransSLR: A Lightweight Transformer for Sign Language Recognition

This work proposes TransSLR, a lightweight Temporal Transformer Encoder trained from scratch on 64-frame normalized pose sequences, with average pooling and a classification head that achieves signer-independent generalization without relying on visual appearance on the CASL-W60 benchmark.
