About 19 years ago, Fraunhofer IIS and the Chair of Information Technology (LIKE) at the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) founded a digital campus radio station. It was a research project aimed at testing technical innovations and digital broadcasting systems and working with FAU students on developing innovative, content-related concepts. The campus radio station has long since outgrown its status as a research project, and in 2022, the broadcasting studio moved from Erlangen’s E-Werk cultural center to the “Blue House” on the Europa Canal in Erlangen. On the occasion of this move, we take a look back at 19 years of fruitful collaboration.

Dr. Alessandra Zarcone holds a PhD in linguistics and works at the interface between natural language processing and cognitive science. She joined Fraunhofer IIS in 2018, where her job focuses on voice assistants and human-machine interaction.

Gender bias and bias in general play an increasing role in natural language processing. AI applications use vast amounts of data to learn associations relating to all kinds of variables or features. But in doing so, they also adopt existing prejudices and stereotypes. In this interview, Dr. Alessandra Zarcone discusses whether gender bias is also a factor in industrial natural language processing, to what extent she herself is concerned with the issue, and whether Fraunhofer IIS is addressing this problem.

Project manager Birgit Brüggemeier is researching intelligent human-machine interaction using voice. Together with other AI experts, she is developing future voice interfaces.

Voice assistants such as Alexa, Siri and the like are becoming more and more popular, but the systems struggle when it comes to understanding complex contents and context or deriving semantic meaning. Birgit Brüggemeier knows what the problem is: »The machine lacks common sense.« Together with her project team, she is working on the European version of a voice assistant, looking at how these error messages can be communicated to the user without them getting annoyed and ending their interaction with the voice assistant.

3D sound that transports viewers to the heart of the action.

Until now, recording high-quality 360° sound or enjoying immersive audio in a home theater was exclusive to users willing to install and operate a multitude of microphones or loudspeakers. Such complex setups will, however, soon be a thing of the past. Thanks to the special algorithms of the Fraunhofer upHear family of technologies capturing and playback of 3D sound is now possible just with a single device.
