Researchers from the Hebrew University of Jerusalem have succeeded for the first time in devising a model that describes and identifies a basic cellular mechanism that enables networks of neurons to efficiently decode speech in changing conditions.
The research may lead to the upgrading of computer algorithms for faster and more precise speech recognition as well as to the development of innovative treatments for auditory problems among adults and young people.
Our brain has the capability to process speech and other complex auditory stimuli and to make sense of them, even when the sound signals reach our ears in a slowed, accelerated or distorted manner.
However, the neuronal mechanisms that enable our brain to perceive a word correctly, for example, that is pronounced in different ways by different speakers or to understand a heavy accent, was a mystery to scientists until now.
Research associate Dr. Robert Gütig and Prof. Haim Sompolinsky of the Edmond and Lily Safra Center for Brain Sciences at the Hebrew University have succeeded in describing a cellular process by which sensory neurons in the brain can automatically adjust their perceptual clocks and thus correct large temporal variations in the rate of sounds and speech that arrive from the environment.
According to their findings, which were recently published in the PLoS Biology journal, the bio-physical mechanism that exists in our brain enables single nerve cells in the cerebral cortex to perform word identification tasks almost perfectly.
The understanding of the process of speech decoding and the possibilities of its implementation in technology – by the development of neural network algorithms for the identification and processing of various patterns of sound signals – could lead to the significant upgrading of speech recognition technology in communications and computing, for instance in telephone voice dialing or in voice and sound monitoring devices.
The technology has been patented by Yissum, the Hebrew University's technology transfer company.

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...

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...
