Audio technology developed by the Fraunhofer IDMT in Oldenburg used in Deutsche Telekom’s smart speaker
The Fraunhofer IDMT in Oldenburg has developed the audio technology for Deutsche Telekom’s smart speaker. At the heart of the work is the optimized interaction of speakers and microphones for voice control even in a noisy environment.

What’s more, the experts have achieved particularly good acoustics for telephony and music playback in a small enclosure. The product will be launched on 31.08.2018 at IFA in Berlin, the trade exhibition for consumer electronics and home appliances.
Oldenburg, 31.08.2018. With their audio development of Deutsche Telekom’s new smart speaker, audio experts from the Fraunhofer Institute for Digital Media Technology IDMT, Branch Hearing, Speech and Audio Technology HSA in Oldenburg have succeeded in creating a superb sound in a small space.
By refining and combining microphone and loudspeaker technologies, they have achieved a very robust voice control system that also works reliably when listening to music at the same time and in a noisy environment.
What was special for the product developers in Oldenburg was the fact that they were involved in the project from the outset and able to contribute their know-how right up to end-of-line testing. This allowed a close and trusting relationship to grow with Deutsche Telekom at a high technical level. “Our experience shows that our clients often want an integrated system and increasingly also trustworthy support in every stage of implementation.
From concept development to first hardware and software prototypes to the start of production – we were able to map all this out for Telekom in the way they wanted,” says Dr. Jens-E. Appell, Head of Branch Speech and Audio Technology HSA at the Fraunhofer IDMT in Oldenburg, underlining the good cooperation between the two organizations.
“Through controllable directional microphones and signal enhancement for recognition of voice commands, we were able to give the device superb ‘hearing’. This also makes itself noticeable when using the integrated hands-free function to make phone calls as well as when accessing other services and operating entertainment equipment,” adds Jan Wellmann, Head of the Audio System Technology Group at Fraunhofer IDMT-HSA in Oldenburg.
“Since the quality of our products is always in the foreground, the main focus for our smart speaker was the acoustics. In first discussions, we quickly recognized that the experts in Oldenburg can assist us throughout the entire development process.
Starting with the finetuning of our first draft designs, followed by the many questions that arose and each stage in product optimization during the course of the development work to quality assurance during the final product inspection, the Fraunhofer IDMT was a reliable partner that accompanied us along the way,” highlights Dirk A. Böttger, Vice President Product Management Fixed Line Devices at Deutsche Telekom.
And: “We believe that voice control in intelligent products has come to stay. This means that it’s time for our smart speaker which complies with German standards. At the same time, the system is explicitly designed as an open platform onto which each and every company and ecosystem can dock – from large supermarket chains such as REWE to corner shops,” continues Böttger.
Numerous functions in compliance with European data protection rules
With the personal assistant, voice control can be used to operate connected devices in the home such as TV and Telekom’s smart home applications – without the need for a remote control. The personal assistant can also be used to make telephone calls – the audio quality is excellent. Other applications are available via cooperation partners such as Radioplayer and the news programme “Tagesschau”.
Users of Amazon’s cloud-based Alexa voice service can also access a large number of apps with Deutsche Telekom’s smart speaker. The new voice-controlled assistant conforms to the highest data security requirements. Data processing takes place exclusively within the European Union and complies with Telekom’s high data protection standards.
Hearing, speech and audio technology at the Fraunhofer Institute for Digital Media Technology IDMT in Oldenburg
The objective of the Branch Hearing, Speech and Audio Technology HSA of the Fraunhofer IDMT in Oldenburg is to transpose scientific findings related to hearing perception into technological applications. Its applied research priorities are the enhancement of sound and speech intelligibility, personalized audio reproduction and acoustic speech and event detection. The fields of application include Consumer Electronics, Transportation, Automotive, Manufacturing, Security, Telecommunications and Health. Through scientific partnerships, it has close links with the Carl von Ossietzky University, Jade University and other institutions in Oldenburg engaged in hearing research. It is also a partner in the »Hearing4all« Cluster of Excellence.
WE MAKE IT LISTEN! » We teach your devices to hear.«
With the speech recognizers developed at the Fraunhofer IDMT-HSA, enterprises can operate their machines reliably even in a loud environment and, if wanted, without transferring data to the internet. Or they can incorporate the speech recognizers in their own products and in this way create unique selling points and generate new value added for their customers.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
