In a previous paper [1], we proposed a new framework for spoken term detection by exploiting user relevance feedback information to estimate better acoustic model parameters to be used in rescoring the spoken segments. In this way, the acoustic models can be trained with a criterion of better retrieval performance, and the retrieval performance can be less dependent on the existence of a set of...

My visit at KTH aimed to develop a system in which audio-visual feedback is provided to users who are free to move in the space. The feedback depends on the expressivity of the body movements they perform. Specifically, users can render a music performance by controlling in realtime acoustic parameters through their full-body movement and get a visual feedback on a screen in front of them with ...

The results of a comparative analysis of feedback strategies used in human-human communication and human-machine communication in Swedish are reported in this paper. The aim of this study is twofold: to provide a categorization of feedback expressions based on contextual information and to verify the hypothesis that acoustic characteristics of feedback expressions can be regarded as cues to the...

To enhance speech intelligibility for people with hearing loss, aids will amplify using gains derived from evidence-based prescriptive methods, in addition to other advanced signal processing mechanisms. While the evidence supports use of aid intelligibility, these adjustments can also be detrimental sound quality, poor quality cited as a barrier device adoption. In general, an uncontrolled env...

Cloud cavitation causes nontrivial energy concentration and acoustic shielding in liquid its control is a long-standing challenge due to complex dynamics of bubble clouds. We present framework study closed-loop through feedback. While previous approaches have used empirical thresholding, we employ model-based state estimation coherent based on theory high-performance computing. Using pulsed ult...

abstract the extent to which teachers’ written corrective feedback (wcf) is conducive to esl learners’ improvement has been discussed since truscott’s claim in 1996. the mentioned debate continues because there has been lots of contrastive research studies with different results. this paper presents the results of a 2-month study of the effectiveness of wcf to 65 low intermediate iranian learne...

To function in human-inhabited environments a robot must be able to press buttons. There are literally thousands of different buttons, which produce various types of feedback when pressed. This work focuses on doorbell buttons, which provide auditory feedback. Our robot learned to predict if a specific pushing movement would press a doorbell button and produce a sound. The robot explored differ...
