Signal Processing, Interpretation and REpresentation (SPIRE) Laboratory

Established in May 2015 at the Indian Institute of Science (IISc), Bangalore, the Signal Processing, Interpretation and, REpresentation Lab (SPIRE Lab), under the direction of Dr. Prasanta Kumar Ghosh, is a leading research hub dedicated to advancing the frontiers of signal processing, speech processing, representation learning, and machine learning. The lab's core focus revolves around the analysis, modeling, and interpretation of human-centered multi-modal signals. This encompasses a wide spectrum of data, including speech, audio, Electrogastrogram (EGG), brain imaging, and various bio-medical signals. SPIRE Lab's research translates theoretical advancements into practical applications across diverse domains, including healthcare, education, and defense. Apart from government agencies, SPIRE lab also has collaborations with various industries and NGOs that specialize in sectors like health, engineering, innovation, data collection, startups etc.

The SPIRE lab is home to many graduates, project associates and interns. It continues to provide opportunities to aspiring candidates to further their career growth. The lab has always fostered a lively environment for research and development. As of January 2025, the lab, along with Dr. Prasanta Kumar Ghosh has contributed 50+ journal articles, 180+ conference papers/posters to the scientific community.

With the growing demand for data in the machine learning community and increased focus of Indian accents and languages, SPIRE lab is also in the process of releasing publicly available data to address this need.
