This thesis draws onthree sets of recordings of Swedish-Russian interpreter-mediated conversations,carried out as role plays. First,scripted role plays, performed as part of the Swedish state interpretercertification test, involving candidate interpreters and officials from thegovernmental body providing these tests. Secondly, both scripted andnon-scripted role plays, performed during interpreter training courses at theSwedish Armed Forces’ Language School. And thirdly, non-scripted role playsorganised in order to explore differences in style between more and lessexperienced official negotiators, working at a high international diplomaticlevel, for Sweden and Russia respectively, assisted by interpreters. The thesisadopts a text-oriented as well as an interactionist approach oninterpreter-mediated interaction and compares the management of turn-taking andrepair sequences in the three types of setting, focusing particularly on howthe presence or absence of a script affects turn-taking and the unfolding ofrepair sequences.

The present study focuses on turn-taking and questions in conversations between deaf-blind persons using tactile sign language, i.e. communicating by holding each others hands, and how sign language utterances change in the tactile mode when the nonmanual signals characteristic of turntaking and interrogative sentences in (visual) sign language are not used. The material consists of six video-recorded conversations (four with deaf-blind pairs and two where one person is deaf and one is deaf-blind). Parts of the material, viz. 168 sequences with questions and answers, has been transcribed and analyzed. The analysis shows that deaf-blind signers use their hands in two different conversation positions. In the monologue position both the signer's hands are held under the hands of the listener, whereas in the dialogue position both participants hold their hands in identical ways: the right hand under the other person's left hand and the left hand on top of the other person's right hand. It is described how the two positions affect the structure of one- and twohanded signs and how back channeling, linguistic as well as non-linguistic (with different kinds of tapping), is used in the two positions. The analysis shows that differences in the vertical and the horizontal planes are used in turn-taking regulation. Using four different conversational levels the signer can signal e.g. turn change by lowering his/her hands from the turn level to the turn change level at the end of his/her turn. The horizontal plane is devided into three different turn zones. The turn holder uses his/her own turn zone close to the body and finishes the turn by moving the hands to the joint zone midway between the interlocutors or into the listener's zone. The analyzed utterances function as questions, yes/no-questions (82) as well as wh-questions (55). It is hypothesized that yes/no-questions are marked with the manual signal extended duration of the last sign of the utterance, one of the interrogative signals of visual signing, but this was only true for 46 % of the yes/no-questions in the material. Since extended duration of the last sign also signals turn change in e.g. statements it is not regarded as an interrogative signal. Additional markers of yes/no-questions are among others the sign INDEX-adr ('you') with its variant INDEX-adr-long, used as a summons signal, and repetitions of signs or sentences. As for the wh-questions a majority are made with a manual wh-sign. Generally, if there are no interrogative signals the context and the content of the utterance will account for its interpretation as a question. To avoid misunderstandings, questions and non-linguistic signals are used in checking turns, where the signer requests back channeling or the listener requests repetition or clarification. / <p>För att köpa boken skicka en beställning till exp@ling.su.se/ To order the book send an e-mail to exp@ling.su.se</p>

Participants in an intercultural situation of communication, trying to understand the intentions of their co-Iocutors from their own cultural perspective, can frequently commit misinterpretations that lead to misunderstandings of intention and meaning. Intercultural communication studies, for the majority, focus on unveiling and discovering differences that they believe to be at the core of such misunderstandings. Such studies have probed the varying cultural values, to mention a few, on the levels of individualism versus collectivism, of low-context versus high-context, of varying concepts of time or of silence (e.g. Hofstede 1980, Hofstede 1991, Hall 1959, Hall & HaU1990). The present study suggests that the perspective of one's primary socialisation culture should be studied on a more specific level if one is aiming to discover possible cultural differences. The level that is proposed to be studied is the production and interpretations of patterns of talk-in-interaction such as pauses, overlaps, speaker changes, simultaneous talk, prosody and intonation patterns, and so on. It is the stance of the present inquiry that these above-mentioned turntaking patterns play a key role in the processes through which the participants interpret each other's meanings and intentions, although the processes themselves remain mostly entirely subconscious. The present study was inspired by a case study that was conducted comparing the turn-taking behaviour between Americans and French conversing in French (Wieland 1991). Wieland conducted recordings of ordinary dinner table conversations, and later interviewed the participants in order to elicit insights into their interpretations of the interaction. However, little work has been done to further compare the culturally varying interaction patterns and the participants' reactions to them. The majority ofstudies into intercultural communication remain on more abstract levels of cultural values rather than addressing the actual arena of talk-in-interaction, although some have broken this unploughed ground, e.g. Moerman (1988) in his combination of conversation analysis and ethnography. The stance of the present study is that it is this very level of talk-in-interaction that holds the key to understanding what exactly happens in possible misunderstandings in situations of intercultural communication. Studies on talk-in-interaction focus on conversational turn-taking (Psathas 1995, Ten Have & Psathas 1995, Sacks, Schegloff & Jefferson 1974, Schegloff 2000). They therefore bring to light behavioural patterns - and their respective interpretations - that most of the time remain subconscious in the minds of the interactants, as those patterns are learned and internalised early on in the primary socialisation process (Berger & Luckmann 1966). Sample analyses on the conversational overlaps of French speakers carried out previously by the researcher (Kohonen 2000) served as a basis for the hypothesis development. These earlier analyses made evident the importance of gaining access to participants' perceptions on the interaction, as well as the access into parameters that allow a comparative approach. The present research is an exploratory, qualitative case study that allowed comparisons to be made between the overlap patterns of the native French and the native British English participants conversing in native and mixed groups, furthermore gaining access to participants' perceptions of the interaction. The present study is not intended to be taken as a strictly conversation analytical research, as the Literature Review will show. The aim of the present study is on the contrary to explore the possible theoretical and methodological triangulations available in the field of social sciences, and to discover how the triangulation of theories and methods could enhance the study of talk-in-interaction, in both native and intercultural settings.

Dogs are well adapted to a life close to humans and are capable of understanding several human social cues. Turn-taking is a fundamental phenomenon in human conversations, yet no research of turn-taking in interspecies vocal communication has been done. This pilot study therefore aimed to develop a test method in order to analyze if turn-taking occurs in interspecies vocal communication between dogs and humans and if turn-taking can be correlated with specific behaviors in dogs. By analyzing a vocal conversation between seven dogs and their owners during a request situation in their home environment, this study found support for turn-taking existence in dog-human vocal communications. In general, owner-dog vocal communication could be linked to positive events, such as tail wagging and eye contact. Meanwhile, a lower frequency of vocal turn- taking could be linked to stress related behaviors, such as lip licking. Owner in dyads where more vocal overlap occurred tended to score the owner-dog relationship and communication abilities with lower grades, suggesting the absence of turn-taking was experienced as unpleasant for the owner as well. In conclusion, findings from current study highlight the unique coevolution of dogs and humans and opens up for future research of turn-taking in interspecies vocal communication.

The study aims at the understanding of the meaning-building process during a group work interaction of tertiary-level students. The article highly emphasizes on the fact that meaning evolves through the interaction of the people, whether verbal or non-verbal, and the group work interaction substantiates the meaning-building process quite emphatically as the interaction is quite intensive and peer-centered. In the way to understand the meaning-making, the study has focused its concentration on turn-taking procedures of the participants as well as the materialization of their competence.

Dogs and humans have through domestication and co-evolution established a close relationship and can communicate and understand each other. The objective of the present study was to deepen the understanding of the communication between dogs and humans, with focus on the vocalized communication. The study was based on video and audio recordings of dog-human communications from a total of 36 dogs in their home environment. The mean gap size in the communication ranged from 0.651.16 seconds and the overlap in communication had a percentage range of 14-50 %. These results are within the frame of other species communication with turn-taking. With these considerations, it clearly indicates that turn-taking occurs in interspecies communication between dogs and humans. The present study suggests that dogs intentionally communicate through vocalisation with their owners to gain the attention of the owner. In addition, age and sex of the dog influence their communication with their owners.

The purpose of this study was to examine the following prosodic elements: speech rate, turn-taking latency, number of interruptions, and utterance duration across two groups' neurotypical and autistic young adults. Furthermore, the end goal of this study is to help provide a baseline and clinical application of prosodic differences between autistic and neurotypical adults. Speech samples were collected from 11 neurotypical and 11 autistic young adults from the ages of 18-26. Speech samples were recorded responses from a 10-minute interview between two research assistants and the autistic or neurotypical individual. Using Praat software, speech samples were analyzed and used to calculate speech rate, utterance duration, turn-taking latency, and the number of interruptions for each subject. Across the four prosodic elements, there were significant differences between the autistic and neurotypical groups. The neurotypical group exhibited significantly higher speech and interruption rates when compared to the autistic group. Whereas, the autistic group displayed longer turn-taking latency periods and longer utterance durations. Across all conditions, there were no significant difference between biological sex or effect of familiarity within the autistic and neurotypical groups. Results of this study provide clinicians and researchers a baseline of prosodic differences found between autistic and neurotypical individuals. Future research is needed to better understand how these findings might improve the assessment and treatment of autistic individuals.

Spoken dialogue systems are application interfaces that enable humans to interact with computers using spoken natural language. A major challenge for these systems is dealing with the ubiquity of variability—in user behavior, in the performance of the various speech and language processing sub-components, and in the dynamics of the task domain. However, as the predominant methodology for dialogue system development is to handcraft the sub-components, these systems typically lack robustness in user interactions. Data-driven methods, on the other hand, have been shown to offer robustness to variability in various domains of computer science and are increasingly being used in dialogue systems research.     This thesis makes four novel contributions to the data-driven methods for spoken dialogue system development. First, a method for interpreting the meaning contained in spoken utterances is presented. Second, an approach for determining when in a user’s speech it is appropriate for the system to give a response is presented. Third, an approach for error detection and analysis in dialogue system interactions is reported. Finally, an implicitly supervised learning approach for knowledge acquisition through the interactive setting of spoken dialogue is presented.      The general approach taken in this thesis is to model dialogue system tasks as a classification problem and investigate features (e.g., lexical, syntactic, semantic, prosodic, and contextual) to train various classifiers on interaction data. The central hypothesis of this thesis is that the models for the aforementioned dialogue system tasks trained using the features proposed here perform better than their corresponding baseline models. The empirical validity of this claim has been assessed through both quantitative and qualitative evaluations, using both objective and subjective measures. / Den här avhandlingen utforskar datadrivna metoder för utveckling av talande dialogsystem. Motivet bakom sådana metoder är att dialogsystem måste kunna hantera en stor variation, i såväl användarnas beteende, som i prestandan hos olika tal- och språkteknologiska delkomponenter. Traditionella tillvägagångssätt, som baseras på handskrivna komponenter i dialogsystem, har ofta svårt att uppvisa robusthet i hanteringen av sådan variation. Datadrivna metoder har visat sig vara robusta mot variation i olika problem inom datavetenskap och artificiell intelligens, och har på senare tid blivit populära även inom forskning kring talande dialogsystem. Den här avhandlingen presenterar fyra nya bidrag till datadrivna metoder för utveckling av talande dialogsystem. Det första bidraget är en datadriven metod för semantisk tolkning av talspråk. Den föreslagna metoden har två viktiga egenskaper: robust hantering av ”ogrammatisk” indata (på grund av talets spontana natur samt fel i taligenkänning), samt bevarande av strukturella relationer mellan koncept i den semantiska representationen. Tidigare metoder för semantisk tolkning av talspråk har typiskt sett endast hanterat den ena av dessa två utmaningar. Det andra bidraget i avhandlingen är en datadriven metod för turtagning i dialogsystem. Den föreslagna modellen utnyttjar prosodi, syntax, semantik samt dialogkontext för att avgöra när i användarens tal som det är lämpligt för systemet att ge respons. Det tredje bidraget är en data-driven metod för detektering av fel och missförstånd i dialogsystem. Där tidigare arbeten har fokuserat på detektering av fel on-line och endast testats i enskilda domäner, presenterats här modeller för analys av fel såväl off-line som on-line, och som tränats samt utvärderats på tre skilda dialogsystemkorpusar. Slutligen presenteras en metod för hur dialogsystem ska kunna tillägna sig ny kunskap genom interaktion med användaren. Metoden är utvärderad i ett scenario där systemet ska bygga upp en kunskapsbas i en geografisk domän genom så kallad "crowdsourcing". Systemet börjar med minimal kunskap och använder den talade dialogen för att både samla ny information och verifiera den kunskap som inhämtats. Den generella ansatsen i den här avhandlingen är att modellera olika uppgifter för dialogsystem som  klassificeringsproblem, och undersöka särdrag i diskursens kontext som kan användas för att träna klassificerare. Under arbetets gång har olika slags lexikala, syntaktiska, prosodiska samt kontextuella särdrag undersökts. En allmän diskussion om dessa särdrags bidrag till modellering av ovannämnda uppgifter utgör ett av avhandlingens huvudsakliga bidrag. En annan central del i avhandlingen är att träna modeller som kan användas direkt i dialogsystem, varför endast automatiskt extraherbara särdrag (som inte kräver manuell uppmärkning) används för att träna modellerna. Vidare utvärderas modellernas prestanda på såväl taligenkänningsresultat som transkriptioner för att undersöka hur robusta de föreslagna metoderna är. Den centrala hypotesen i denna avhandling är att modeller som tränas med de föreslagna kontextuella särdragen presterar bättre än en referensmodell. Giltigheten hos denna hypotes har bedömts med såväl kvalitativa som kvantitativa utvärderingar, som nyttjar både objektiva och subjektiva mått. / <p>QC 20160225</p>

Medical error and patient safety have become important issues. It is clear that medical error is more influenced by systemic factors rather than human characteristics. Communication patterns, in particular interruptive communication, maybe one of the systemic factors that contribute to the burden of medical error. Objective: An exploratory study to examine interruptive communication patterns of healthcare staff within an intensive care unit during ward rounds. Methods: The study was conducted in a tertiary hospital in Sydney, Australia. Nine participants were observed individually, for a total of 24 hours, using the Communication Observation Method (COM). The amount of time spent in conversation, the number of conversation initiating and number of turn-taking interruptions were recorded. Results: Participants averaged 75% [95% confidence interval 72.8-77.2] of their time in communication events during ward rounds. There were 345 conversation-initiating interruptions (C.I.I.) and 492 turn-taking interruptions (T.T.I.). C.I.I. accounted for 37% [95%CI 33.9-40.1] of total communication event time (5hr: 53min). T.T.I. accounted for 5.3% of total communication event time (56min). Conclusion: This is the first study to specifically examine turn-taking interruptions in a clinical setting. Staff in this intensive care unit spent the majority of their time in communication. Turn taking interruptions within conversations occurred at about the same frequency as conversation initiating interruptions, which have been the subject of earlier studies. These results suggest that the overall burden of interruptions in some settings may be significantly higher than previously suspected.
