Perception and Reproduction of Auditory Spatial Impression

As audio reproduction systems evolve to incorporate many loudspeakers, the potential to evoke faithful auditory spatial impressions increases. Psychoacoustic principles of auditory spatial perception, and methods for production and reproduction of acoustic ...

Improved overlap speech diarization of meeting recordings using long-term conversational features

Hervé Bourlard, Sree Harsha Yella

Overlapping speech is a source of significant errors in speaker diarization of spontaneous meeting recordings. Recent works on speaker diarization have attempted to solve the problem of overlap detection using classifiers trained on acoustic and spatial fe ...

Wordless Sounds: Robust Speaker Diarization using Privacy-Preserving Audio Representations

Hervé Bourlard, Daniel Gatica-Perez, Sree Hari Krishnan Parthasarathi

This paper investigates robust privacy-sensitive audio features for speaker diarization in multiparty conversations: ie., a set of audio features having low linguistic information for speaker diarization in a single and multiple distant microphone scenario ...

EnviroMeter: A Platform for Querying Community-Sensed Data

Karl Aberer, Dipanjan Chakraborty, Saket Sathe

Efficiently querying data collected from Large-area Communitydriven Sensor Networks (LCSNs) is a new and challenging problem. In our previous works, we proposed adaptive techniques for learning models (e.g., statistical, non-parametric, etc.) from such dat ...

Method and arrangement for measuring the distance to an object

Cristiano Niclass

Arrangement (10) for measuring the distance to an object, comprising: a photonic source for illuminating said object using a continuous modulated photonic wave, a solid-state image sensor, comprising an array of avalanche photodiodes and a plurality of cir ...

A Simple Continuous Pitch Estimation Algorithm

Petr Motlicek, Philip Neil Garner, Milos Cernak

Recent work in text to speech synthesis has pointed to the benefit of using a continuous pitch estimate; that is, one that records pitch even when voicing is not present. Such an approach typically requires interpolation. The purpose of this paper is to sh ...

Processing and Consolidation of TaC/HfC Based Composites Using MoSi2 and Carbon Nanotubes

Mehdi Mazaheri

Tantalum and hafnium carbides are classified as Ultra High Temperature Ceramics (UHTC) because of their extreme melting temperatures (above 3900 degrees C). Therefore, these materials can safely operate in the range of temperature that any other materials ...

Echo thresholds for reflections from acoustically diffusive architectural surfaces

Christof Faller, Andreas Walther

When sound reflects from an irregular architectural surface, it spreads spatially and temporally. Extensive research has been devoted to prediction and measurement of diffusion, but less has focused on its perceptual effects. This paper examines the effect ...

EMG-based pattern recognition approach in post stroke robot-aided rehabilitation: a feasibility study

Silvestro Micera

Background: Several studies investigating the use of electromyographic (EMG) signals in robot-based stroke neurorehabilitation to enhance functional recovery. Here we explored whether a classical EMG-based patterns recognition approach could be employed to ...

Speaker diarization of overlapping speech based on silence distribution in meeting recordings

Fabio Valente, Sree Harsha Yella

Speaker diarization of meetings can be significantly improved by overlap handling. Several previous works have explored the use of different features such as spectral, spatial and energy for overlap detection. This paper proposes a method to estimate proba ...
