Distributed Spatial Audio Coding in Wireless Hearing Aids

Martin Vetterli, Olivier Roy

The information content of binaural signals can be beneficial to many algorithms deployed in current digital hearing aids. However, the exchange of such signals over a wireless communication link requires transmission schemes that must fulfill demanding te ...

Collaborating Hearing Aids

Martin Vetterli, Olivier Roy

Hearing aids are electronic, battery-operated sensing devices which aim at compensating various kinds of hearing impairments by means of appropriate signal processing. Most of today's hearing aid systems consist of two appliances working independently of e ...

Discriminant linear processing of time-frequency plane

Hynek Hermansky, Fabio Valente

Extending previous works done on considerably smaller data sets, the paper studies linear discriminant analysis of about 30 hours of phoneme-labeled speech data in the time-frequency domain. Analysis is carried both independently in time and frequency and ...

Spatio-Temporal Sampling and Distributed Compression of the Sound Field

Martin Vetterli, Emre Telatar, Luciano Sbaiz, Olivier Roy, Thibaut Ajdler, Robert Konsbruck

We investigate how the sound field induced by an acoustic event evolves over space and time. The characteristics of its bidimensional Fourier spectrum are analyzed and spatio-temporal sampling results using an array of microphones are provided for differen ...

New implantable hearing device based on a micro-actuator that is directly coupled to the inner ear fluid

Yves Perriard, Hans Bernhard

A new hearing therapy called Direct Acoustical Cochlear Stimulation (DACS) was developed and validated in a first clinical trial with four patients. The key component of this therapy based on an implantable hearing device is a micro-actuator that is implan ...

AV16.3: an Audio-Visual Corpus for Speaker Localization and Tracking

Daniel Gatica-Perez, Jean-Marc Odobez, Guillaume Lathoud

Assessing the quality of a speaker localization or tracking algorithm on a few short examples is difficult, especially when the ground-truth is absent or not well defined. One step towards systematic performance evaluation of such algorithms is to provide ...

Stochastic techniques in deriving perceptual knowledge

Hynek Hermansky

The paper argues on examples of selected past works that stochastic and knowledge-based approaches do not contradict each other. Frequency resolution of human hearing is decreasing with increasing frequency. Spectral basis designed for optimal discriminati ...

Binaural localization and separation techniques

Harald Viste

Abstract Based on binaural signals, i.e. the signals observed at the two ears, a listener can localize and recognize different sound sources and then focus on one of these. For decades, researchers have tried to invent a machine that can do the same under ...
