In Real Time: Automatic call transcription in call centers


From research into the market: EML European Media Laboratory to present the benefits of real time speech analytics for call centers at the international exhibition CCW 2016 in Berlin

The Heidelberg-based IT company EML European Media Laboratory GmbH will be presenting its products at this year’s CCW trade fair (hall 2, C19). The fair is taking place in Berlin from February 23rd to 25th. More than 7000 visitors are expected.

At the CCW, the Heidelberg speech recognition experts will show applications for telephone customer contact that allow for real-time transcription of incoming customer calls into text. The recognized text can be further processed fast and easily.

Newest technologies for speech recognition

The “EML Transcription Server” automatically converts incoming phone calls, speaker-independent and in real-time, into machine-searchable text. "We apply neural networks and deep learning techniques," explains R & D manager Dr. Siegfried Kunzmann. "Thus we achieve excellent recognition rates." In a further step, the “EML Speech Mining Server” classifies the recognition results according to predefined categories, calculates the frequency of certain expressions and keywords and finally links the results with each other. Real-time speech recognition facilitates the monitoring and efficient verification of conversation guidelines of call centers.

Automatic transcription is the key requisite for efficient, extended search for particular keywords. In conventional systems every new keyword search involves the reprocessing of all calls, that is of all recorded audio data. EML's “Advanced Keyword Spotting“, however, finds keywords in the recognized text as quickly as a search engine. The keywords can also be linked with each other. In addition, the phonetic search function will find words that are not yet included in the speech recognition vocabulary - unusual names, for example.

Individual customization and privacy

Call center operators can furthermore adapt the speech recognition to their own application domains. With the launch of a new product, the adaptation process allows to easily add product descriptions or new keywords to the language model. This makes it possible to quickly recognize current issues or emerging trends. Another advantage of this customization is that “speech recognition and model adaption take place on the companies’ own premises which guarantees data protection,” says Dr. Siegfried Kunzmann.

Voicemail: Reading is faster than listening

EML’s speech technologists also demonstrate the “EML Voicemail2Text Service“ and the corresponding Android app for automatic transcription of voicemails. This service is free of charge for private users. With the “EML Voicemail2Text Service” owners of a VoIP router, such as Fritz!Box, can receive an automatic transcription of incoming voicemails on their smartphones without additional installations on their router. They simply sign up at or use the „EML Voicemail App“ that can be downloaded for free at the Google Play Store.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
