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

Widespread adoption of GaAs-based solar cells for space applications has also brought about large reductions in material costs. However, GaAs cells are still much more expensive than silicon cells. This application addresses the development of a manufacturable technique for lifting off thin films of GaAs. This approach allows a significantly reduced cost due to reduced materials usage, while maintaining high efficiency. Light-trapping for lifted-off cells will also be developed, which will allow the theoretical limit to performance to be approached, and fundamental processes in GaAs to be investigated.
