We present EchoSpeech, a minimally-obtrusive silent speech interface (SSI) powered by
low-power active acoustic sensing. EchoSpeech uses speakers and microphones mounted …

Silent speech interface is a promising technology that enables private communications in
natural language. However, previous approaches only support a small and inflexible …

Silent speech recognition (SSR) allows users to speak to the device without making a
sound, avoiding being overheard or disturbing others. Compared to the video-based …

We present HPSpeech, a silent speech interface for commodity headphones. HPSpeech
utilizes the existing speakers of the headphones to emit inaudible acoustic signals. The …

This paper presents EarIO, an AI-powered acoustic sensing technology that allows an
earable (eg, earphone) to continuously track facial expressions using two pairs of …

Ground surfaces are often carefully designed and engineered with various textures to fit the
functionalities of human environments and thus could contain rich context information for …

This research presents a music theory-inspired acoustic representation (hereafter, MTAR) to
address improved speech emotion recognition. The recognition of emotion in speech and …

Silent Speech Interfaces (SSI) on mobile devices offer a privacy-friendly alternative to
conventional voice input methods. Previous research has primarily focused on smartphones …

Sensing movements and gestures inside the oral cavity has been a long-standing challenge
for the wearable research community. This paper introduces EchoNose, a novel nose …

Nod and shake of one's head are intuitive and universal gestures in communication. As
smartwatches become increasingly intelligent through advances in user activity sensing …
