Two types of transient responses have been investigated in fly motion-sensitive neurons in the past: the impulse and the step response. In response to a brief motion pulse, cells show a sudden rise in activity followed by an exponential decay ('impulse response'). In response to the onset of a constant velocity stimulus, cells exhibit transient oscillations before settling to a steady-state val...
We developed the head impulse testing device (HITD) based on an inertial sensing system allowing to investigate the functional performance of the rotational vestibulo-ocular reflex (VOR) by testing its gaze stabilization ability, independently from the subject's visual acuity, in response to head impulses at different head angular accelerations ranging from 2000 to 7000 deg/s(2). HITD was initi...
This paper addresses the problem of time-varying channels in speech-recognition-based human-robot interaction using Locally-Normalized Filter-Bank features (LNFB), and training strategies that compensate for microphone response and room acoustics. Testing utterances were generated by re-recording the Aurora-4 testing database using a PR2 mobile robot, equipped with a Kinect audio interface whil...
This paper proposes a robust feature extraction method for automatic speech recognition (ASR) systems in reverberant environment. In this method, a sub-band power envelope inverse filtering algorithm based on the modulation transfer function (MTF), that we have previously proposed, is incorporated as a front-end processor for ASR. The impulse response of the room acoustics is assumed to be expo...
