This paper investigates intonational strategies for backchanneling in Bari Italian task-oriented dialogues. Results show that whilst giving feedback, listeners indicate their intention to take the floor or not by using a falling or rising intonation contour respectively. However, this general tendency can be reversed if added paralinguistic meanings are conveyed.

Six paralinguistic information types uttered by three subjects were examined. Considerable changes were observed in duration, pitch, vowel formant, and voice quality. These findings require some reconsideration of the problems in the phrase phonology of Japanese like mora-based timing and phrase-initial pitch movement. On the other hand, lexically specified phonological features were more robus...

We propose a non-invasive and cost-effective method to automatically detect dementia by utilizing solely speech audio data. extract paralinguistic features for short segment use Gated Convolutional Neural Networks (GCNN) classify it into or healthy. evaluate our on the Pitt Corpus own dataset, PROMPT Database. Our yields accuracy of 73.1% using an average 114 seconds In Database, 74.7% 4 data i...

Object manipulation techniques in robotics can be categorized in two major groups including manipulation with and without grasp. The aim of this paper is to develop an object manipulation method where in addition to being grasp-less, the manipulation task is done in a passive approach. In this method, linear and angular positions of the object are changed and its manipulation path is controlled...

In this paper, we describe a system developed for hands free audio analysis for a living room environment. It comprises detection and localisation of the verbal and paralinguistic events, which can augment the behaviour of virtual director and improve the overall experience of interactions between spatially separated families and friends. The results show good performance in reverberant environ...

Phonetic manifestation of paralinguistic information (PI) like speaker’s attitude and intention is a unique property of speech communication. Production and perception of six PI types were examined using Japanese. In speech production, acoustic and articulatory analyses revealed that speech signal and the underlying articulatory gesture differed systematically and considerably under the specifi...
