Modern speaker verification systems rely on a variety of input sources in making a decision on the validity of an identity claim. The meaning of the evidence these sources produce must be reconciled if robust decisions are to be made. In the case of Conversational Biometrics (CB), for example, this is typically accomplished via the specification of a verification policy implemented as a finite ...

This paper focuses on the implementation of a novel semantic-based Conversational Agent (CA) framework. Traditional CAs interpret scripts consisting of structural patterns of sentences. User input is matched against such patterns and an associated response is sent as output. This traditional CA approach, which solely takes into account the structural form of a sentence, requires the scripter to...

In the past researchers have questioned the effectiveness of ethics training in higher education. Also, there are observations that support the view that ethical behaviour (range of actions)/ethical decision making models used in the past make use of vignettes to explain ethical behaviour. The understanding remains in the perspective that these vignettes play a limited role in determining indiv...

The goal of this paper is to show how to accomplish a more enjoyable and enthusiastic dialogue through the analysis of human-to-human conversational dialogues. We first created a conversational dialogue corpus annotated with two types of tags: one type indicates the particular aspects of the utterance itself, while the other indicates the degree of enthusiasm. We then investigated the relations...

This paper discusses some ideas for the requirements and methods of conversational speech synthesis, based on experience gained from the collection and analysis of a very large corpus of conversational speech in a variety of real-life everyday contexts. It shows that because variation in voice quality plays a significant part in the transmission of interpersonal and affect-related social inform...
