Conference calls that almost feel as if the participants were in the same room? This dream could soon come true thanks to the Immersive Voice and Audio Services (IVAS) codec, a technology that creates a spatial experience during phone calls or teleconferences. IVAS makes conversations feel more vivid, which improves communication.

AI algorithms that generate text, images, or videos based solely on prompts – i.e., input in human language – will play a major role in business, research, and society in the future. Known as generative algorithms, these broaden the options for making use of artificial intelligence. And Fraunhofer IIS is at the forefront of their development.

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.

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.

New sound technologies make it possible to craft highly realistic audio experiences in which the sound comes from all sides – even from above. Sound engineer Daniela Rieger completed her Master of Engineering at Stuttgart Media University and is part of the team in the Media Systems and Applications department at Fraunhofer IIS, where she works to optimize these types of audio formats.

Transmitting 4K and 8K resolutions in production quality via Ethernet can’t be done? Think again! The new JPEG XS video codec was “custom designed“ for the migration of broadcast studios and productions to Internet Protocol (IP). Building on JPEG XS, we developed a software-based en-/decoding solution that has come through its baptism of fire as a market-ready solution for production under real conditions. Together with the Japanese broadcaster NHK, we have successfully completed a pilot test for 8K transmission.

When Elena Burdiel talks about her work in the Audio Coding & Multimedia Software group at the Fraunhofer Institute for Integrated Circuits IIS in Erlangen, you immediately notice her enthusiasm and how her eyes light up. It quickly becomes clear that her world revolves (almost) entirely around music and sound. But delving a little deeper reveals that the 29-year-old has many exciting qualities that make her a unique “innovation artist” in the Nuremberg metropolitan region.

Voice assistants are growing in popularity and are even being adopted in industry. To work reliably, they need to »hear« voice commands clearly and must be trained to understand what is being said. A platform »made in Germany« is needed in order to retain ultimate control over these training models and the data the assistant collects. The Fraunhofer SPEAKER project is pursuing precisely that objective.

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.

Hybrid radios merge analog, digital and Internet radio together. They allow users to listen to a regional radio program even when they are outside its broadcasting range. We offer software solutions that enable car radios to use all three sources. Furthermore, our audio codecs ensure good audio quality even at low bit rates.
