Current advances on dialogue system require the development of language models for automatic speech recognition that are not only domain or task specific but also sub-task specific (e.g. name, age or price recognition). This paper presents a method for the creation of language models for name recognition at the greeting stage of a conversation in spoken Spanish. In particular, we focus on the i...

Their 'croop', for example, is used during greeting of mates, but also during agonistic encounters, and provides an ideal case to study whether calls are revealing with respect to motivational states. We recorded croop calls in a semi-tame and free-roaming flock of Northern Bald Ibis in...

We demonstrate a novel method for producing a synthetic talking head. The method is based on earlier work in which the behaviour of a synthetic individual is generated by reference to a probabilistic model of interactive behaviour within the visual domain such models are learnt automatically from typical interactions. We extend this work into a combined visual and auditory domain and employ a s...
