The Heidelberg IT enterprise EML European Media Laboratory will be represented at this year’s CallCenterWorld in Berlin (28 February to 1 March 2012) with a stand of its own (Hall 5, Stand A8).
EML offers enterprises speech technology solutions for their customer contacts over the phone. The “EML Transcription Platform” provides automatic transformation of incoming phone calls into written text, analysis of the calls, and the tuning of the speech recognition performance to customer-specific application domains.
At CallCenterWorld, EML’s speech technology experts will be demonstrating a novelty: “domain adaptation.” It enables users to adapt speech recognition to their own application domains at short notice and without assistance. For instance, an enterprise launching a new product can quickly and effectively insert product descriptions or new keywords into the language model.
Another unique selling point that EML has to offer is that speech recognition and domain adaptation capabilities will be available to enterprises on their own premises. “That safeguards data protection issues,” says Dr. Siegfried Kunzmann, head of research and development.
Incoming phone calls are automatically transformed into written text and classified in accordance with call-center-specific product or problem categories, patterns or conversational features. In addition, the calls are scanned for new terms and linked up with one another accordingly. The automatic transcription now boasts “advanced keyword spotting,” an extension of the search function for particular keywords.In conventional systems, every new keyword search involves reprocessing and rescanning all incoming calls that have been recorded. “Advanced Keyword Spotting finds the keywords in recognized texts as quickly as a search engine,” says Dr. Kunzmann. “And the new phonetic search function means we can find keywords not yet registered in the speech recognition system, for example unusual proper names.”

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
