Research

The research conducted in the unit is of highest international quality, in many of these areas, and the cooperation tight with several ICT and other high-tech companies.

With these companies, we boost practical applications that create societal impact.

Metrology Research Institute

Metrology Research Institute focuses on optical radiation measurements and related activities. We do not forecast the weather!

Communication acoustics: spatial sound and psychoacoustics

Capturing, transmission, reproduction, synthesis, and perception of sound - these are the fields that interest us in the communication acoustics team.

Audio signal processing

We are working on wideband sound technology, which is extensively applicable for example in smart phones, music technology, gaming, sound reproduction, and noise control.

Speech communication technology

Speech communication technology aims at describing, explaining and reproducing communication by speech.

Speech production

Speech recognition

Our goal is to generally improve the speech recognition methodology with the help of the new algorithms developed in Aalto University. Speech recognition offers challenging benchmarking tasks for efficient algorithms that can process and learn to represent large quantities of data.

Speech Interaction Technology

Our objective is to improve spoken interaction, in applications such as telecommunication as well as when using speech interfaces.

Group Members

Virtual Acoustics

The Virtual Acoustics Research Group is concentrating on room acoustics – how it could be measured, simulated, and auralized as well as how humans perceive different rooms, in particular the team is world-know on the research of concert halls.

Sound In Virtual Reality

We combine spatial audio, acoustic simulation, and auditory perception with interaction and narrative design
