Experience unprecedented quality for speech, music and mixed content with Fraunhofer IIS' communication solutions. Explore the future of phone calls, teleconferences and voice-controlled human-machine interaction.



The Allinga voice assistant solution uses the latest AI technology. Two modules, namely speech recognition and speech synthesis “Allinga Voice”, are currently available, and function completely independently of one another. They provide a fully customizable voice assistant system that is compliant with European data-protection standards and with full data sovereignty. Further components are currently in development.



The new LC3/LC3plus audio codec was developed in order to solve essential shortcomings present in today’s wireless communication platforms such as Bluetooth and Digital Enhanced Cordless Telecommunications (DECT). The codec’s operation modes range from medium bit rates for optimal voice transmission up to high bit rates for high-resolution music streaming services.  


upHear Voice Quality Enhancement

The Fraunhofer upHear Voice Quality Enhancement (VQE) software is designed to facilitate voice-controlled human-machine interactions using microphones built into mobile phones and smart home devices such as smart speakers.

AAC-ELD Family

Already being widely used for professional and consumer communication applications, are state-of-the-art MPEG-4 audio codecs for maximum speech and audio quality at very low coding delay.  


EVS is especially designed for VoLTE (Voice over LTE) services. It enables phone calls with Full-HD Voice quality, bringing call fidelity up to the same level as today’s other digital media services.

Spatial Audio Conferencing

The technology renders participants of a teleconference into a 3D soundstage and allows listening over stereo headsets.
