Unlabeled Sensing of Multi-Input FRI Signals
Shannon's sampling theorem for bandlimited signals, formulated in 1949, has become a cornerstone for modern digital communications and signal processing. The importance of sampling and reconstruction of analog signals has led to great advances in the field ...
2022Probabilistic Symbol Sequence Matching and its Application to Pathological Speech Intelligibility Assessment
Matching of a test signal to a reference word hypothesis forms the core of many speech processing problems, including objective speech intelligibility assessment. This paper first shows that the comparison of two speech signals can be formulated as matchin ...
Idiap2021AM-FM DECOMPOSITION OF SPEECH SIGNAL: APPLICATIONS FOR SPEECH PRIVACY AND DIAGNOSIS
Petr Motlicek, Hynek Hermansky, Sriram Ganapathy, Amrutha Prasad
Although current trends in speech processing consider deep learning through data-driven technologies, many potential applications exhibit lack of training or development data. Therefore, considerably light signal processing techniques are still of interest ...

2019Sampling the Multiple Facets of Light
The theme of this thesis revolves around three important manifestations of light, namely its corpuscular, wave and electromagnetic nature. Our goal is to exploit these principles to analyze, design and build imaging modalities by developing new signal proc ...
EPFL2018Method and apparatus for presenting to a user of a wearable apparatus additional information related to an audio scene
Martin Vetterli, Ivan Dokmanic, Juri Ranieri
A method for presenting to a user of a wearable audio device a modified audio scene together with additional information related to the audio scene, comprising: capturing audio signals with a plurality of microphones; outputting an audio signal with a plur ...
2017"Can you hear me now?"
This thesis deals with signal-based methods that predict how listeners perceive speech quality in telecommunications. Such tools, called objective quality measures, are of great interest in the telecommunications industry to evaluate how new or deployed sy ...
EPFL2016Enhancing Measurement Quality through Active Sampling in Mobile Air Quality Monitoring Sensor Networks
Alcherio Martinoli, Ali Marjovi, Adrian Arfire
In recent years, a growing number of research groups have targeted the development and deployment of networks using low-cost chemical sensors for monitoring air quality. Due to economical reasoning, most of these systems make use of some sort of mobility t ...
IEEE2016Novel GCC-PHAT Model in Diffuse Sound Field for Microphone Array Pairwise Distance Based Calibration
Hervé Bourlard, Afsaneh Asaei, Mohammadjavad Taghizadeh
We propose a novel formulation of the generalized cross correlation with phase transform (GCC-PHAT) for a pair of microphones in diffuse sound field. This formulation elucidates the links between the microphone distances and the GCC-PHAT output. Hence, it ...
2015Incentives for Truthful Information Elicitation of Continuous Signals
We consider settings where a collective intelligence is formed by aggregating information contributed from many independent agents, such as product reviews, community sensing, or opinion polls. We propose a novel mechanism that elicits both private signals ...
