Hands off in real time: the many advantages of call transcription for customer contact

06.02.2017

From research into the market: EML European Media Laboratory demonstrates how real-time speech analytics benefit call centers at the 2017 CCW International Trade Show in Berlin

Once again this year the Heidelberg-based IT company EML European Media Laboratory GmbH will have its own stand (Hall 2, Stand C19) at the telecommunications trade show CCW. The show will run from February 21 to 23 in Berlin and is expected to attract more than 7,000 visitors.

The Heidelberg speech recognition experts will present applications for telephone customer contact that transcribe incoming calls into text in real time. The recognition results can then be further processed, quickly and easily.

State-of-the-art technologies for speech recognition

The EML Transcription Server immediately converts incoming calls into machine-searchable text, automatically and speaker independent. “We use machine learning techniques like neural networks and deep learning,” explains EML’s R&D manager Dr Siegfried Kunzmann, “which enable us to achieve the highest recognition rates.”

The EML Speech Mining Server then classifies the results according to pre-defined categories, the frequency of certain expressions, and keywords; it identifies new terms that occur frequently and combines the results. Real-time speech recognition also makes it possible to verify and monitor compliance with conversation guidelines at the call center, simply and efficiently.

Automatic call transcription facilitates the efficient, extended search for certain keywords. With every new keyword search, conventional systems have to re-process and check all calls, that is, all recorded audio data. Advance Keyword Spotting, on the other hand, finds keywords in the converted text as quickly as a search engine. “Of course, we support traditional Keyword Spotting (KWS), as well,” Siegfried Kunzmann explains, “but Advanced Keyword Spotting does much more: you can connect the keywords with one another.”

Customized marketing tool

In addition, call center operators can adapt speech recognition to their own application domains. When a new product is launched, for instance, the product description and new keywords can be added to the language model. Immediate issues or emerging trends are thus quickly recognized.

Employing speech recognition also allows the call center to elucidate exactly how many callers have used a certain product name – interesting information for a company’s strategy and marketing departments: after all, the calls are authentic customer statements which can be used to adapt products, services and activities more quickly and directly. “This helps employees in call centers to be more efficient and customer friendly in their communication with callers,” says Dr Kunzmann.

Data protection

Another advantage of domain adaptation is that speech recognition and model adaption are conducted on premise, within their own four walls. “This means call centers can comply with the strict German data protection legislation,” Dr Kunzmann summarizes.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
