Elements of interactivity in telephone conversations
نویسندگان
چکیده
The term “interactivity” has been defined in numerous ways in the context of communications, but a definition of interactivity as an instrumentally measurable parameter of conversations is still missing. In this paper, we approach this issue by applying a parametric analysis to telephone conversations recorded during speech quality tests. To this end, we extract the basic conversational parameters like speech activity, mutual silence and double talk as well as a set of conversation events like speaker alternation rate and interruption rate. Comparing two types of scenarios for conversational speech quality assessment and exploring four different situations with regard to transmission delay, we aim at understanding the interdependencies between the conversational parameters which are basic for studying interactivity. This is intended to, ultimately, lead to an instrumental metric distilled from the relevant parameters.

Telephone Conversation Closing Structure Across English and Persian
Due to the lack of paralinguistic information, politeness gains a considerable significance in telephone conversations (TCs). The use of politeness strategies can help interlocutors promote and/or maintain social harmony in telephone interactions. Using the Rapport Management Model proposed by Spencer-Oatey (2008), this study intended to primarily investigate the fundamental closing structures ...

Modeling the interactivity of conversations recently has gained increasing interest in the telecommunications community, especially with regard to the integration of multimedia applications over packet-based transmission technologies. A quantitative description of interactivity either relies on (subjective) user tests or on instrumental (objective) metrics which use appropriate signal parameter...

متن کاملMeasuring Non-Spontaneous Interactivity: An Opera-related Case Study
Defining an instrumental concept of interactivity is a fundamental prerequisite for the investigation of interactive multimedia. Unfortunately, this has turned out to be a non-trivial task. Thus, we have recently proposed several approaches for characterizing the interactivity of spontaneous speech conversations. In this paper, we apply our methodology to the non-spontaneous case as represented...
متن کاملHot discussion or frosty dialogue? towards a temperature metric for conversational interactivity
Despite of its evident importance, measuring interactivity as a central parameter for characterizing conversations has not experienced much attention so far. Starting with an axiomatic approach and using thermodynamic concepts, this paper proposes “conversational temperature” as a new interactivity metric. The resulting scalar parameter is easily to be determined from standard measurements with...
