Audio signal processing

The Audio Signal Processing Research Group is working on wideband sound technology, which is extensively applicable for example in mobile phones, music technology, and noise control.

Speech technology

The Speech Technology research group works on developing new methods and approaches to discovering and processing patterned information within speech and audio signals.

Speech communication technology

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

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.

Deep learning can fool listeners by imitating any guitar amplifier

A study from the Aalto Acoustics Lab demonstrates that digital simulations of guitar amplifiers can sound just like the real thing. The implications are that as the software models continue to improve, they can replace traditional analogue guitar amplifiers, which are bulky, fragile and expensive.
