Where rigorous research meets real-world impact
INFERENCE Lab publishes across speech intelligence, natural language processing, human-centered sensing, and applied AI — with each study designed from the ground up to be reproducible, citable, and deployable. Our work spans clinical voice diagnostics, low-resource corpora, cognitive fatigue detection, and post-quantum cryptography.
Research Areas & Domains
Our lab focuses on fundamental problems where theoretical rigor can be translated into open software, benchmarks, and clinical-grade tools.
Low-Resource Speech Intelligence & Acoustic Biomarkers
Pioneering clinical-grade vocal fatigue screening, speaker verification, and emotion recognition from raw speech. Developing novel neural representations (e.g. ECAPA-TDNN-VHE) that operate robustly with minimal training data.
Key Topics & Pipelines:
Low-Resource NLP & Regional Language Corpora
Curating large-scale foundational corpora and benchmarking language models for Roman Urdu and under-represented South Asian dialects. We build data-centric pipelines that enforce high inter-annotator agreement and privacy-preserving embeddings.
Key Topics & Pipelines:
Human-Centered Sensing & Cognitive Ergonomics
Investigating unobtrusive digital biomarkers—such as cursor kinematics and workstation interaction logs—as indicators of cognitive workload, acute stress, and fatigue in knowledge work and clinical environments.
Key Topics & Pipelines:
Deployable AI Systems & Security
Bridging scientific discovery and production engineering. Every research artifact is packaged into pip-installable libraries (PyPI), verifiable registries, and benchmarked cryptographic schemes.
