Much of the recent literature on freedom speech has focused arguments for and against regulation certain kinds speech. Discussions hate offensive speech, example, abound in this literature, as do debates concerning permissibility pornography. Less attention been paid, however, at least recently, to normative foundations where three classic justifications still prevail, based values truth, auton...

Using speech in computer interaction is advantageous in many situation and more natural for the user. However, development of speech enabled applications presents, in general, a big challenge when designing the application, regarding the implementation of speech modalities and what the speech recognizer will understand. In this paper we present the context of our work, describe the major challe...

In human communication, direct speech (e.g., Mary said: "I'm hungry") is perceived to be more vivid than indirect speech (e.g., Mary said [that] she was hungry). However, the processing consequences of this distinction are largely unclear. In two experiments, participants were asked to either orally (Experiment 1) or silently (Experiment 2, eye-tracking) read written stories that contained eith...

I present a language for specifying planning problems in which there are external events, that is, events beyond the direct control of the planner which may happen while a plan is being executed. The language is based on Miller and Shanahan’s representation of narratives in the situation calculus. I describe an implemented planner that produces correct plans for this language, and discuss how s...

Projection in the situation calculus refers to answering queries about the future evolutions of the modeled domain, while progression refers to updating the logical representation of the initial state so that it reflects the changes due to an executed action. In the general case projection is not decidable and progression may require second-order logic. In this paper we focus on a recent result...

In this paper, we propose the modulation-domain Kalman filter (MDKF) for speech enhancement. In contrast to previous modulation domain-enhancement methods based on bandpass filtering, the MDKF is an adaptive and linear MMSE estimator that uses models of the temporal changes of the magnitude spectrum for both speech and noise. Also, because the Kalman filter is a joint magnitude and phase spectr...

A set of simple new procedures has been developed to enable the real-time manipulation of speech parameters. The proposed method uses pitch-adaptive spectral analysis combined with a surface reconstruction method in the time-frequency region, and an excitation source design based on phase manipulation. The proposed procedures preserve the details of time-frequency surfaces while almost perfectl...

This paper defines talker characterization problem and contrasts it to the related problems of talker verification and identification. The requirement is to automatically separate and tag talkers in a conference environment using a microphone array and unconstrained speech. An approach which uses a continuous ergodic HMM organized over broad phonemic categories using non-parametric observation ...

Purpose This paper aims to explore drivers of the effectiveness risk assessments in workshops. Design/methodology/approach study uses an agent-based model simulate Combining notions transactive memory and ideal speech situation, this establishes a assessment benchmark then investigates real-world deviations from benchmark. Specifically, models limits information transfer, incomplete discussions...
