This project aims to discover how a biologically inspired auditory model can be tightly integrated into a state-of-the-art deep learning speech processing framework, to model, design and verify a deep learning based auditory model. Voice-based technologies, ranging from cochlear implants to smart homes, are growing at a rapid pace and speech interfaces are being integrated with all aspects of our lives. However, there is a growing demand to improve these voice-enabled services, making them more secure and less open to cyber-crime attack by unauthorised users. The project is expected to improve techniques for modelling and automatic processing of speech and audio signals, which should provide significant benefits, including improved voice biometrics and cochlear implants.Read moreRead less

Signal separation and tracking for augmented hearables and wearables. This project aims to develop augmentation technology in hearables, via solutions for source separation and tracking. Hearing is one of the five human senses. Augmented hearables or wearable devices with augmented hearing would extend and enhance hearing.

Dynamic substrates for surface-enhanced Raman scattering: piezoelectric actuated nanotextures with phase-locked signal processing. Surface-enhanced Raman scattering shows great promise for sensitive detection of a wide range of chemical and biological compounds. Novel electronic devices will be produced to actively tune the nanometre scale structures that generate the scattering signal, resulting in an improved fundamental understanding and control of the effect.

This project will build hollow-core metamaterial waveguides, where the large dimension (a few millimetres) of current rigid waveguides will be reduced to a few tens of microns. This project will demonstrate tuneable spectral filtering using these novel waveguides, leading to realisation of the world's first hollow-core waveguide-based metamaterial device.
