Sound and vision are two of the senses we most heavily rely on in our everyday lives. Advances in computer vision have profoundly impacted our daily lives and greatly bridged the gap between human and machine intelligence. Despite being less explored, audio contains just as much rich information about the activities, events, and environments around us. Audio is vital in many applications and has numerous advantages that position it to be the most pervasive sensing modality in mobile and intelligent systems: 1) less power consuming and computational requirements; 2) greater omnidirectional coverage; 3) less impacted by physical obstructions; 4) cheaper and more portable sensors; and 5) less privacy intrusive. Audio intelligence will enable low-power, low-cost, real-time, hands-free, and more interactive communication between machines, humans, and the environment. This workshop aims to push the boundaries of machine intelligence by exploring the sensing, communication, system implementation, algorithm design, and applications of intelligent acoustic systems.

IASA welcomes contributions in all aspects of acoustic sensing, systems, and applications, including mobile and wearable sensing or communication utilizing sound, vibration, ultrasound, and infrasound, algorithms in acoustic intelligence, security and privacy utilizing acoustics, and data or deployment experiences.

• Large language models (LLMs) for acoustic understanding and generation
• Self-supervised learning (SSL) acoustic foundation models
• Few-shot and zero-shot learning for acoustic applications
• Transformer-based architectures for acoustic processing
• Energy-efficient deployment of acoustic foundation models on resource-constrained devices

In addition to the research papers, we also invite “Challenge Papers” that present revolutionary new ideas that challenge existing assumptions prevalent among acoustic signal processing, machine learning, and the mobile systems community in general. These “challenge papers” should provide stimulating ideas that may open up exciting avenues and/or influence the direction of future intelligent acoustic research. An exhaustive evaluation of the proposed ideas is not necessary for this category; instead, insight and in-depth understanding of the issues are expected.

We invite original research papers that have not been previously published and are not currently under review for publication elsewhere. All submitted papers will be evaluated through a single-blind reviewing process. Submitted papers should be no longer than six pages for research papers and four pages for challenge papers (including references and appendices). Your submission must use a 10pt font (or larger) and be correctly formatted for printing on Letter-sized (8.5" by 11") paper. Paper text blocks must follow ACM guidelines: double-column, with each column 9.25" by 3.33", 0.33" space between columns and single-spaced. The title of challenge papers must bear a "Challenge:" prefix.

Papers are to be submitted at: https://iasa2025.hotcrp.com

All accepted papers will be published as part of the ACM proceedings.

• Camera-ready papers should adhere to the ACM templates that can be found here: http://www.acm.org/publications/proceedings-template. Templates are provided for formatting papers in MS Word and LaTeX. In LaTeX, you should use \documentclass[sigconf, 10pt]{acmart}.
• Font size no smaller than 10 points.
• Please do NOT number the pages of your camera-ready paper (by default page numbers are disabled in the ACM template).
• You should provide proper indexing information in the final version according to the ACM Computing Classification System (CCS). More information about the ACM CCS is available on the ACM CCS website.
• Avoid using any special characters or non-standard fonts. We must be able to display and print your submission exactly as we receive it using only standard tools and printers, so we strongly suggest that you use only standard fonts embedded in the PDF file.
