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.

“Fraunhofer IIS is definitely a special place“

„The positive work environment and being together with long-standing colleagues mean a lot to me”, explains Dr. Bernhard Grill, director and division head at Fraunhofer IIS. Grill has been at the institute since the early days and played a key part in its rise from the level of a working group to become a world-renowned research institute. He has also been a member of the institute’s management team since 2016. We asked him about his professional responsibilities and his most special places away from work.

A revolution in tv sound

MPEG-H Audio allows users to adjust the audio mix themselves.

For the first time in decades, a revolution in TV sound is about to enter our homes. With the exception of the introduction of 5.1 surround sound, TV has previously offered little in the way of audio innovations. Now, sound on TV and the Internet is about to become individual and capable of filling whole rooms. With the new audio codec MPEG-H Audio, TV and Internet audiences will be able to adjust their own soundmix and bring 3D cinema sound to their own homes.

Immersed in Sound

Fraunhofer Cingo® supplies perfect 3D sound for virtual reality headsets.

Fraunhofer IIS has been successfully developing audio coding technologies for many years. The goal of these technologies is to store and transmit audio signals in optimum quality. But what good is having the best audio quality if devices can only reproduce it inadequately? To address this prob- lem, scientists at Fraunhofer IIS have developed the Cingo® and Symphoria® technologies to improve playback sound quality.

Catching the Light - Film Technology of the future

Fraunhofer IIS's technology saves the entire light information for a scene.

Shooting is finished. During post-production, errors are discovered that had previously gone unnoticed. With light-field processing, this is no problem. The technology offers new possibilities for film production and allows scenes to be modified.
