Non-Manual Articulators In Irish Sign Language Verbs: An Analysis With Data Mining Association Rules, Robert G. Smith, Markus Hofmann

Conference Papers

The Signs of Ireland (SOI) corpus (Leeson et al., 2006) deploys a complex multi-tiered temporal data structure. The process of manually analyzing such data is laborious, cannot eliminate bias and often, important patterns can go completely unnoticed. In addition to this, as a result of the complex nature of grammatical structures contained in the corpus, identifying complex linguistic associations or patterns across tiers is simply too intricate a task for a human to carry out in an acceptable timeframe. This work explores the application of data mining techniques on a set of multi-tiered temporal data from the SOI corpus. Building …

Investigating Prosodic Accommodation In Clinical Interviews With Depressed Patients, Brian Vaughan, Carolina De Pasquale, Lorna Wilson, Charlie Cullen, Brian Lawlor

Conference Papers

Six in-depth clinical interviews, involving six elderly female patients (aged 60+) and one female psychiatrist, were recorded and analysed for a number of prosodic accommodation variables.

Our analysis focused on pitch, speaking time, and vowel-space ratio. Findings indicate that there is a dynamic manifestation of prosodic accommodation over the course of the interactions. There is clear adaptation on the part of the psychiatrist, even going so far as to have a reduced vowel-space ratio, mirroring a reduced vowel-space ratio in the depressed patients. Previous research has found a reduced vowel-space ratio to be associated with psychological distress; however, we suggest …

Providing Objective Metrics Of Team Communication Skills Via Interpersonal Coordination Mechanisms, Celine De Looze, Brian Vaughan, Finnian Kelly, Alison Kay

Conference Papers

Being able to communicate efficiently has been acknowledged as a vital skill in many different domains. In particular, team communication skills are of key importance in the operation of complex machinery such as aircrafts, maritime vessels and such other, highly-specialized, civilian or military vehicles, as well as the performance of complex tasks in the medical domain. In this paper, we propose to use prosodic accommodation and turn- taking organisation to provide objective metrics of communica- tion skills. To do this, human-factors evaluations, via a coordi- nation Demand Analysis (CDA), were used in conjunction with a dynamic model of prosodic accommodation …

Measuring Variations Of Mimicry By Means Of Prosodic Cues In Task-Based Scenarios And Conversational Speech, Brian Vaughan, Celine De Looze

Other resources

Here, we address the measurement of mimicry, that is when speakers’ speech variations look like parallel patterns.

As a definition of mimicry, we often read in the literature description such as mimicry is “The situation where the observed behaviours of two inter-actants although dissimilar at the start of the interaction are moving towards behavioral matching”. These types of descriptions imply that mimicry is a linear phenomenon and that speakers tend to imitate over time. However, it can be assumed, especially when studying spontaneous speech, that there are rather phases of mimicry and non-mimicry and that mimicry should be rather …

Task-Based Mood Induction Procedures For The Elicitation Of Natural Emotional Responses., Brian Vaughan, Charlie Cullen, Spyros Kousidis, Yi Wang

Other resources

This paper details experimental procedures designed to elicit real emotional responses from participants within a controlled acoustic environment. The experiments use Mood Induction Procedures (MIP’s), specifically MIP 4, to implement a co-operative task using two participants. These cooperative tasks are designed to engender emotional responses of activation and evaluation from the participants who are situated in separate isolation booths, thus reducing unwanted noise in the signal, preventing the participants from being distracted and ensuring a cleanly recorded audio signal. The audio is recorded at a professional level of quality (24bit/192Khz). The emotional dimensions of each audio recording will be evaluated …
