Press release from: audEERING GmbH

The competence and professionalism of call center service agents is an important precondition for customer satisfaction. Systematically training call center agents requires an automatic analysis of various conversation parameters, like meeting the goals set by the company and defining the predominant atmosphere during the call. This is what the company audEERING, founded by the internationally renowned Affective Computing expert Prof. Björn Schuller (University of Passau and Imperial College London), is specializing on. Together with the Swiss company Spitch, a leading provider of solutions for automatic speech recognition (ASR), voice user interfaces (VOI), and speech analytics, audEERING is integrating new technologies for automatic recognition of emotions in call center environments to allow for personalized training of service agents and improvement of service quality in call centers.

Gilching/Oberpfaffenhofen - Zurich, 28.02.2017. The market for call centers is growing steadily since almost every company is nowadays offering their customers some kind of a service desk. Online shops, mobile phone providers, banks or insurance companies offer instant support by telephone for their customers. But not only the number of call centers is growing – so is the frustration on both ends of the line. Angry customers complain about long waiting times and swamped call center agents – about high levels of stress. To continuously improve service quality, agents need to be trained regularly – not only on technical aspects but also with respect to their general communication skills. The evidence base for such trainings are automatically analyzed calls.

One of the most important parameters for customer satisfaction during a service call is the predominant atmosphere, determined by emotions of agent and caller. Emotions may also affect the customer answers affecting Net Promoter Score (NPS) measurements. Due to decades of research at the Technische Universität München (TUM), the company audEERING, which was founded by former TUM employees, is able to offer an automated solution for emotion and personality recognition. Modern approaches for pattern recognition allow for reliable automatic recognition of emotions from speech signals. The core technology for this comes from the software toolkit “openSMILE” which was developed by audEERING and has received multiple awards.

In a joint project with the Swiss company Spitch, audEERING’s audio analysis methods are being optimized for service call recordings. For calibrating of the recognition software with respect to the service call domain, real call center audio recordings are used and labeled by experts in order to “teach” the software extracting emotions in a learning phase. The labeling of speech recordings is performed by the innovative crowdsourcing technology applied within the iHEARu-PLAY platform, which was developed by audEERING in cooperation with the University of Passau. iHEARu-PLAY is a platform allowing its users to assign emotions to recordings via the internet.

“Every innovative company nowadays explores new approaches for productive customer interaction. Speech, voice, and emotion recognition can be seen as essential elements of a continuative business strategy. Spitch is a leading provider of speech and voice recognition and we are happy about the cooperation with audEERING, the leading vendor in the area of emotion recognition from audio. Together, we offer a complete integration of identification, verification, speech recognition, and emotion recognition, allowing our customers to use this potential for competitive advantages”, says Alexey Popov, CEO and founder of Spitch.

„By this trend-setting solution and cooperation between audEERING and Spitch, companies can not only profit from enhanced customer satisfaction due to better training and prevention measures – they also get support in improving psychological stress of call center agents. This generates added value on all areas”, adds Univ.-Prof. Dr. Björn Schuller, CEO of audEERING.
