Assistive Speech and Language Analysis

Against this background, the Assistive Speech and Language Analysis Group is working on the integration of speech therapy know-how into digital applications. At the centre of the group’s applied research are computer-assisted digital technologies for automatic language, speech and voice assessment. Here, the Oldenburg team is using and further developing its own technical methods for automatic speech recognition, acoustic voice analysis and digital signal processing as well as machine learning and computational linguistics.

In health research, the Assistive Speech and Language Analysis Group is making a significant contribution to counteracting the social withdrawal of persons affected by speech problems, for example due to illnesses such as Parkinson’s disease or after a stroke, and to helping them communicate. In addition, language features are applied as biomarkers, contributing in this way to the prevention and early detection of disease. The group’s language technologies and activities also support language education and literacy as well as their accessibility for a broader public via digital learning platforms.

Combining AI and mobile devices generates analysis and assessment tools for a wide range of health-related and learning applications, which are also available on a privacy-compliant server infrastructure.

Our services for you

Assistive speech and language analysis make a significant contribution to connected health and thus also to pioneering health research. To this end, Fraunhofer IDMT is working closely with the European Medical School at the University of Oldenburg. In addition to voice and speech analyses, researchers are also studying and developing the recording of biosignals as a means to describe health and other vital parameters through body-worn sensors.

Findings from research and development are transposed into practice in the shape of mobile, sensor-based systems that can be used flexibly and without clinical infrastructure. As networked technological solutions, they facilitate improved diagnostics and therapy for specific diseases as well as digital language learning and support.

Insight into our reseach and practice


Listening and pronunciation training for the hearing impaired

The developments in the project THERESIAH are intended to complement existing forms of therapy.


Intelligent speech training with ISi-Speech

In the ISi-Speech project, a training system is being developed that allows affected persons to independently train their speech capability. 


Connected Health

The work area Connected Health dedicates its research and development activities to sensor-based health systems that can be deployed flexibly and without clinical infrastructure.

Speech Recognition for Products and Processes

Speech detection systems allow operation of technical systems without visual or physical contact. The speech recognition technology of the Fraunhofer IDMT in Oldenburg functions robustly - with and without an internet connection.
