New developments in voice biometrics

17.07.2007
A new method which will allow more effective voice discrimination has been developed by researchers at the University of Hertfordshire.

Dr Aladdin Ariyaeeinia at the University’s School of Electronic Communication & Electrical Engineering and his team have 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 team’s most recent development is a new approach to speaker change detection, a process which captures when speakers change in a given conversational audio stream which could have very useful applications in criminal investigations and in managing audio-visual recordings.

According to Dr Ariyaeeinia, whose paper on this subject will soon be published in the IEEE Transactions on Audio, Speech and Language Processing, their new approach which incorporates Gaussian mixture models, is significantly more effective than any current techniques for speaker change detection.

“We have proved that through the use of this new method, the accuracy of speaker change detection can be enhanced by 30%,” said Dr Ariyaeeinia.

According to his paper, this is achieved through an effective means for tackling the problem posed by phonetic variation in speaker change detection, and by providing the capability for dealing with undesired effects of variations in speech characteristics.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

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...

Im Focus: Designing Architecture with Solar Building Envelopes

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...
