Call For Papers

Scope and Topics

Among the five human senses, we most heavily rely on sound and vision in our everyday lives. Advances in computer vision have profoundly impacted our daily lives and greatly bridged the gap between human and machine intelligence. However, without exploiting the rich information about the activities, events, and environment around us embedded in audio, it is not possible to fully unleash the potential of machine intelligence. Though many physical characteristics of acoustics have been explored, it has been rarely explored with the lens of pervasive sensing modality in mobile and intelligent systems. Audio presents numerous opportunities, including – (1) reduced power consumption and computational requirements; (2) higher omnidirectional coverage; (3) more susceptibility to physical obstruction; (4) cheaper and smaller sensors; and (5) better privacy preservation. Acoustic 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.

Topics of interest include, but not limited to:
  • Acoustic mobile applications and embedded systems
  • Novel acoustic sensors
  • Innovative acoustic sensing wearables, devices, and platforms
  • Novel software architectures for audio processing
  • Authentication and verification with audio
  • Privacy preservation of continuous listening devices
  • New acoustic features for information extraction
  • Audio augmented reality, AR/VR/Immersive reality applications of acoustic
  • Audio synthesis
  • Sound localization, denoising, and separation
  • Resource-efficient machine learning and artificial intelligence using acoustic signals
  • Multi-modal sensing and learning where acoustic modality enhances or gets enhanced by other sensing modalities
  • Audio + X; where X = edge computing, localization, battery-less, deep learning, robotics, etc
  • Multi-task learning leveraging wearables with microphones
  • Acoustic passive sensing support for vehicular and mobile robotic systems
  • Acoustic sensing in miniaturized aerial devices
  • Communication with audible sounds, ultra-sounds, infra-sound, and vibration
  • Quality-aware audio data collection with earables and wearables
  • Health and wellbeing applications utilizing acoustic signals
  • Emerging applications in earables based on audio signals

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.

Submission Guideline

We invite original research papers that have not been previously published and are not currently under review for publication elsewhere. 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.
