IMPROVING MICROPHONE ARRAY SPEECH RECOGNITION WITH COCHLEAR IMPLANT-LIKE SPECTRALLY REDUCED SPEECH

Philip Neil Garner, Mohammadjavad Taghizadeh

Cochlear implant-like spectrally reduced speech (SRS) has previously been shown to afford robustness to additive noise. In this paper, it is evaluated in the context of microphone array based automatic speech recognition (ASR). It is compared to and combin ...

Continuous Speech Recognition using Boosted Binary Features

Sébastien Marcel, Anindya Roy

A novel parts-based binary-valued feature termed Boosted Binary Feature (BBF) was recently proposed for ASR. Such features look at specific pairs of time-frequency bins in the spectro-temporal plane. The most discriminative of these features are selected b ...

The variability of contact position errors in apraxic imitation

Aude Billard, Biljana Petreska von Ritter-Zahony

Apraxia is a poorly understood disorder of voluntary movement that is not due to basic sensory, motor or cognitive deficits. We conducted a study on the imitation of meaningless gestures in apraxic patients with left fronto-temporo-parietal lesions. In a f ...

Floor Holder Detection and End of Speaker Turn Prediction in Meetings

Hervé Bourlard

We propose a novel fully automatic framework to detect which meeting participant is currently holding the conversational floor and when the current speaker turn is going to finish. Two sets of experiments were conducted on a large collection of multiparty ...

High spatial and spectral resolution long-range sensing using Brillouin echoes

Luc Thévenaz, Stella Foaleng Mafang

High spatial (~cm) and spectral (~MHz) resolution Brillouin sensing is realized with enhanced signal to noise ratio using a pre-activated acoustic field and an optical phase control over the interrogating pulse. Pre-activation of the acoustic field preserv ...

Adaptive sensorimotor peripersonal space representation and motor learning for a humanoid robot

Micha Hersch

This thesis presents possible computational mechanisms by which a humanoid robot can develop a coherent representation of the space within its reach (its peripersonal space), and use it to control its movements. Those mechanisms are inspired by current the ...

Non-linear mapping for multi-channel speech separation and robust overlapping speech recognition

Hervé Bourlard, John David Scott Dines, Weifeng Li

This paper investigates a non-linear mapping approach to extract robust features for ASR and separation of overlapping speech. Based on our previous studies, we continue to use two additional sound sources, namely, from the target and interfering speakers. ...

Automatic Out-of-Language Detection Based on Confidence Measures Derived fromLVCSR Word and Phone Lattices

Petr Motlicek

Confidence Measures (CMs) estimated from Large Vocabulary Continuous Speech Recognition (LVCSR) outputs are commonly used metrics to detect incorrectly recognized words. In this paper, we propose to exploit CMs derived from frame-based word and phone poste ...

A Neural Network based Regression Approach for Recognizing Simultaneous Speech

Hervé Bourlard, John David Scott Dines, Weifeng Li

This paper presents our approach for automatic speech recognition (ASR) of overlapping speech. Our system consists of two principal components: a speech separation component and a feature estmation component. In the speech separation phase, we first estima ...
