A Study of Prosodic Entrainment and Social Factors in Mandarin Conversations

In conversations, interlocutors usually adopt prosody to that of their partner, and they become similar in prosodic production for successful communication. This phenomenon of prosodic entrainment is related to complex factors. This study aims to explore the relationship between prosodic entrainment and social factors. Two analyses are accomplished: the analysis of prosodic entrainment and gender, and the analysis of prosodic entrainment and role. In terms of prosodic entrainment and gender, it is found that the most prosodic features are entrained in female-male conversations, and the least in male-male conversations. In terms of prosodic entrainment and roles, it is found that different roles have influence on the entrainment degree, and information givers entrain more to followers in conversation

Investigating Automatic Measurements of Prosodic Accommodation and Its Dynamics in Social Interaction

Spoken dialogue systems are increasingly being used to facilitate and enhance human communication. While these interactive systems can process the linguistic aspects of human communication, they are not yet capable of processing the complex dynamics involved in social interaction, such as the adaptation on the part of interlocutors. Providing interactive systems with the capacity to process and exhibit this accommodation could however improve their efficiency and make machines more socially-competent interactants. At present, no automatic system is available to process prosodic accommodation, nor do any clear measures exist that quantify its dynamic manifestation. While it can be observed to be a monotonically manifest property, it is our hypotheses that it evolves dynamically with functional social aspects. In this paper, we propose an automatic system for its measurement and the capture of its dynamic manifestation. We investigate the evolution of prosodic accommodation in 41 Japanese dyadic telephone conversations and discuss its manifestation in relation to its functions in social interaction. Overall, our study shows that prosodic accommodation changes dynamically over the course of a conversation and across conversations, and that these dynamics inform about the naturalness of the conversation flow, the speakers’ degree of involvement and their affinity in the conversation

Acomodación fonética durante las interacciones conversacionales: una visión general

During conversational interactions such as tutoring, instruction-giving tasks, verbal negotiations, or just talking with friends, interlocutors’ behaviors experience a series of changes due to the characteristics of their counterpart and to the interaction itself. These changes are pervasively present in every social interaction, and most of them occur in the sounds and rhythms of our speech, which is known as acoustic-prosodic accommodation, or simply phonetic accommodation. The consequences, linguistic and social constraints, and underlying cognitive mechanisms of phonetic accommodation have been studied for at least 50 years, due to the importance of the phenomenon to several disciplines such as linguistics, psychology, and sociology. Based on the analysis and synthesis of the existing empirical research literature, in this paper we present a structured and comprehensive review of the qualities, functions, onto- and phylogenetic development, and modalities of phonetic accommodation.Durante las interacciones conversacionales como dar una tutoría, dar instrucciones, las negociaciones verbales, o simplemente hablar con amigos, los comportamientos de las personas experimentan una serie de cambios debido a las características de su interlocutor y a la interacción en sí. Estos cambios están presentes en cada interacción social, y la mayoría de ellos ocurre en los sonidos y ritmos del habla, lo cual se conoce como acomodación acústico-prosódica, o simplemente acomodación fonética. Las consecuencias, las limitaciones lingüísticas y sociales, y los mecanismos cognitivos subyacentes a la acomodación fonética se han estudiado durante al menos 50 años, debido a la importancia del fenómeno para varias disciplinas como la lingüística, la psicología, y la sociología. A partir del análisis y síntesis de la literatura de investigación empírica existente, en este artículo presentamos una revisión estructurada y exhaustiva de las cualidades, funciones, desarrollo onto- y filogenético, y modalidades de la acomodación fonética

Turn-Taking and Affirmative Cue Words in Task-Oriented Dialogue

As interactive voice response systems spread at a rapid pace, providing an increasingly more complex functionality, it is becoming clear that the challenges of such systems are not solely associated to their synthesis and recognition capabilities. Rather, issues such as the coordination of turn exchanges between system and user, or the correct generation and understanding of words that may convey multiple meanings, appear to play an important role in system usability. This thesis explores those two issues in the Columbia Games Corpus, a collection of spontaneous task-oriented dialogues in Standard American English. We provide evidence of the existence of seven turn-yielding cues -- prosodic, acoustic and syntactic events strongly associated with conversational turn endings -- and show that the likelihood of a turn-taking attempt from the interlocutor increases linearly with the number of cues conjointly displayed by the speaker. We present similar results related to six backchannel-inviting cues -- events that invite the interlocutor to produce a short utterance conveying continued attention. Additionally, we describe a series of studies of affirmative cue words -- a family of cue words such as 'okay' or 'alright' that speakers use frequently in conversation for several purposes: for acknowledging what the interlocutor has said, or for cueing the start of a new topic, among others. We find differences in the acoustic/prosodic realization of such functions, but observe that contextual information figures prominently in human disambiguation of these words. We also conduct machine learning experiments to explore the automatic classification of affirmative cue words. Finally, we examine a novel measure of speaker entrainment related to the usage of these words, showing its association with task success and dialogue coordination

An investigation into patterns of interaction in small teaching groups at Rhodes University, with particular emphasis on the effect of gender, mother-tongue and educational background

The assumption underlying this study is that knowledge is constructed through interaction. Small teaching groups, or tutorials, are often regarded as a particularly effective context for learning in the setting of tertiary education in that they provide an environment for free interaction between students, and thus facilitate active learning. Factors which systematically affect the degree of participation of the individual in tutorIals -directly affect the learning experience of that individual and raise questions about the equality achieved in tutorials, in terms of opportunities for learning. This study focuses on one such type of factor: culturally acquired norms of interaction. The individual is seen as a composite of cultural identities, utilising norms acquired through socialisation and experience in appropriate contexts. Previous research has demonstrated that gendered norms of interaction and those associated with the individual's mother-tongue are particularly salient. In the educational context, norms acquired through previous experience of education are likely to be carried over to the new setting of the university. Thus these factors form the focus of this study. One flrst-year tutorial from each of five departments in the Faculties of Arts and Social Science at Rhodes University, Grahamstown, was video-recorded and the data thus obtained was analyzed for patterns of interaction in terms of gender, mother-tongue and educational background. A model of utterance types was developed to provide a structured description of the patterns found in the tutorials. Interviews and video-sessions with a sample of the tutorial members were conducted, which add a qualitative dimension to the investigation and allow for triangulation. The recorded tutorials and interviews reveal a marked awareness amongst students of the composition of tutorial groups in terms of gender and ethnicity and this composition appears to affect the relative participation of students, in that members of numerically dominant groups are more willing to participate. This is particularly clear in the case of female students. With regard to second-language (L2) speakers of English, a number of factors are highlighted which tend to decrease participation. Apart from problems with English as the medium of instruction, these students tend to be reluctant to participate due to cultural norms, according to which students, as subordinates, should not take the initiative in interaction, in order to show appropriate respect. Patterns of interaction by L2 students from racially integrated schools, however, do not conform to this set of norms as strongly. It is argued that sensitivity is required to address this situation and a number of options are presented
