Dr Aladdin Ariyaeeinia at the University’s School of Electronic Communication & Electrical Engineering has been conducting research into voice biometrics (speaker recognition) for over 10 years. The process has various potential applications such as verifying individuals’ identities when they try to access cash machines or try to bank or shop online.
“The technique we have developed works well in different environments because it encompasses methods to reduce the effects of background noise,” said Dr Ariyaeeinia.
“The process of verifying a claimant will result in a match score. This represents the similarity of the user’s voice to the reference material for the identity being claimed. The University’s method operates in such a way that when the claimant is an impostor, his/her verification score will be suppressed in relation to those for genuine claimants.”
The research in the above area has been the basis for the User Voice Identification (URVIN) project at the University. This is funded by DTI under the New Wave Technologies and Markets programme, and is conducted in collaboration with industry.
Another area of investigation in Dr Ariyaeeinia’s group is the use of voice biometrics for the indexation of conversational audio. This project (part funded by EPSRC) has already led to the development of effective methods for audio data navigation and retrieval. The technique has valuable applications in managing audio-visual recordings, and in processing audio surveillance material for the purpose of combating crime.
Dr Ariyaeeinia commented: “Voice biometrics has the advantage of being useful in areas where you cannot use other biometrics. For instance, the increase in the use of online and telephone banking is expected to lead to the deployment of voice biometrics as an additional means of security.”
Dr Ariyaeeinia’s team is also looking at the fusion of different types of biometrics. The primary purpose of this work on multimodal biometrics is to achieve a level of reliability beyond that obtainable with individual types of biometrics.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
