Real-time, Automatic Transcription of Phone Calls for Call Centers

23.02.2015

EML European Media Laboratory presents the advantages of real-time speech analytics in call centers at the international trade fair CCW in Berlin

The Heidelberg-based IT enterprise EML European Media Laboratory GmbH is again represented with a booth (hall 4, booth H13) at the CCW trade fair for telecommunication in Berlin from 24 February to February 2015. More than 7,000 visitors are expected at the fair.

EML speech technologists present their voice technology applications at the CCW which allow the real-time transcription of incoming customer calls into text. The recognized text can be further processed fast and easily.

The “EML Transcription Server” automatically converts incoming phone calls, speaker-independent and in real-time, into machine-searchable text. In a further step, the “EML Speech Mining Server” classifies the recognition results according to predefined categories, frequency of certain expressions and keywords and finally links the results. Real-time speech recognition facilitates the monitoring and efficient verification of conversation guidelines of call centers.

The automatic transcription allows an 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. “Advanced Keyword Spotting“ however finds keywords in the recognized texts as quickly as a search engine. The keywords can also be linked with each other. The phonetic search function can also find words that are not yet included in the speech recognition vocabulary, like for example unusual names.

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, R&D manager at EML.

Voicemails: Reading is faster than Listening

EML’s speech technologists also demonstrate the “EML Voicemail2Text Service“ and the corresponding Android app for the 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 https://vmt.eml.org/ or use the „EML Voicemail App“ that can be downloaded for free at the Google Play Store.

EML European Media Laboratory GmbH:
EML European Media Laboratory GmbH was established as a private IT enterprise by Klaus Tschira, a co-founder of SAP. EML develops software and technologies in automatic speech processing. The main focus is on the automatic conversion of speech into text (transcription) which is used for telephone (speech analytics, voicemail) and mobile applications (voice texting, voice search).

Im Focus: Hauchdünne magnetische Materialien für zukünftige Quantentechnologien entwickelt

Zweidimensionale magnetische Strukturen gelten als vielversprechendes Material für neuartige Datenspeicher, da sich die magnetischen Eigenschaften einzelner Molekülen untersuchen und verändern lassen. Forscher haben nun erstmals einen hauchdünnen Ferrimagneten hergestellt, bei dem sich Moleküle mit verschiedenen magnetischen Zentren auf einer Goldfläche selbst zu einem Schachbrettmuster anordnen. Dies berichten Wissenschaftler des Swiss Nanoscience Institutes der Universität Basel und des Paul Scherrer Institutes in der Wissenschaftszeitschrift «Nature Communications».

Ferrimagneten besitzen zwei magnetische Zentren, deren Magnetismus verschieden stark ist und in entgegengesetzte Richtungen zeigt. Zweidimensionale, quasi...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
