Towards Sensing Acoustic Cyber-Physical Coupling for Novel Mobile Systems

This paper presents recent findings on two novel mobile systems that leverage the acoustic coupling between mobile devices and the physical environment. Firstly, an acoustic sensing system is developed for mobile telecommunication systems, utilizing the reverberation of sound in rooms to detect robocallers. This approach aims to address the prevalent issue of unwanted automated calls. Secondly, the paper explores the concept of bone conduction in speech and introduces a speech enhancement system specifically designed for head-mounted wearables. By leveraging bone conduction technology, VibVoice system is developed to improve the speech quality in noisy environments.
