2025 IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP 2025) is a flagship conference on speech and audio processing, which was held in Hyderabad from 6 to 11 April. IIIT Hyderabad participated very actively in ICASSP 2025 in various capacities. Faculty, students and staff from IIIT Hyderabad have played their fair share in the successful organization of the conference.

The following are the highlights of IIIT Hyderabad @ ICASSP: 

• IIIT Hyderabad was a sponsor of ICASSP. A sponsorship booth was given to IIIT, where posters related to some centers of interest to ICASSP and smart city living lab were showcased. Prof. Santosh coordinated the setup of the IIIT booth at the conference. The sponsorship benefit itself was offered because IIITH provided eduroam support to the entire conference by installing a server at the venue. Sriranjani and Prakash, along with Prof. Sachin, held multiple discussions with the organizing committee and HICC before the conference. Madhubabu from the IT team gave in-person support at the conference venue. Hundreds of attendees joined the network through the eduroam server.
•  Prof. Jayanthi served on the awards committee. The awards committee was responsible for selecting the best papers in the conference. She also gave an invited talk in the NeuroDA workshop and was a panelist in the PROGRESS workshop.
•  Prof. Sachin co-chaired the ICASSP Show and Tell Demos session. The ICASSP 2025 Show and Tell emphasized the demonstration of novel and interactive signal processing innovations. A total of 47 proposals were submitted from around the world.The Show and Tell sessions were a big success, drawing large crowds of curious attendees. People actively engaged with the presenters, asking questions and having lively discussions about the demos.
•  Prof. Lalitha served as the local organization committee chair of the conference. She (along with the other co-chairs) was responsible for most of the local arrangements and contributed heavily along with the rest of the organizing committee.
•  Prof. Anil Vuppala (along with his students) entirely took care of the poster printing activity. This activity was very crucial to the conference since for around 1300 posters, the authors could not come to the conference. Based on the available posters and video presentations in the conference portal, around 1200 posters were printed along with the video QR code. Prof. Anil and his students have taken care of this humongous activity, all by themselves.
•  Student volunteers: Around 30 students from IIITH (primarily from SPCRC, LTRC and CVIT) very actively volunteered for the organization of ICASSP. They had volunteered for more than half of the entire poster sessions (this is around 150+ in number). As part of volunteering, the students would put up posters in the poster area and ensure the smooth organization of the poster sessions. IIIT students were the most active volunteers in the entire conference. They also helped with setting up videos, helped the general chairs with ICASSP50 Pavilion and many other tasks.

   

• Prof. Bapi Raju organized the Neuro Data Analytics workshop at the conference and Prof. Vinoo Alluri co- organized the workshop on Indian Music Analysis and Generative Applications.
