“…in which the duration between consecutive behaviors is always the same) are often present in music, less strict periodicities can be observed in different chorusing behaviors (9) and styles of speech (47), especially if they involve a social context. For example, when dyads read out loud, the temporal regularity of their speech increases (48,49). Our results provide new evidence on these types of activity patterns and show that spontaneous conversational activities in small groups can exhibit both bursty (type I) and isochronous (type II) dynamics at the aggregate level.…”

Interpersonal coordination is assumed to be a complex phenomenon due to the large number of factors involved and the non-trivial way in which they interact. Temporal collective patterns, including coordination, may emerge during natural conversations in ways that cannot be predicted from the behavior of the participants alone. The characterization of these complex patterns is still challenging but is necessary in order to understand the emergence of coordination at the collective level. We aim to characterize the structural complexity and long-term dynamics of the acoustic activity at the group level. To do so, we performed different analyses: Burstiness, Allan factor analysis, Recurrence quantification analysis, and BPM estimation using a sliding window technique on the time series of a corpus of small group conversations and their randomized and isochronous versions. Together, these analyses showed that the collective acoustic rhythm has a structural complexity that reorganizes over time and that, despite their intrinsic differences, conversations can exhibit two distinct levels of complexity. By uncovering these regularities, our results complement previous knowledge on the complexity of interpersonal coordination on short timescales. Further studies in this direction should evaluate the validity of this approach and findings in different experimental settings

“…For example, studies on the rhythmic characteristics of infantcompared to adult-directed speech have shown that: a) English, Catalan and Spanish mothers present less durational variability of consonantal and vocalic intervals as well as longer vowel duration when speaking to their children compared to addressing adults (Payne et al, 2009); b) in Australian English delta modulations corresponding to the prosodic stress is greater in infant-than in adult-directed speech, while theta modulations, tracking syllable patterns, dominated the adult-directed speech modulation spectrum (Leong et al, 2017). Not only do speech rhythm vary depending on the interlocutors' characteristics, but the presence itself of an interlocutor (i.e., reading partner) has been shown to influence the degree of rhythm entrainment in synchronous reading tasks (Cerda-Oñate et al, 2021). In light of these findings, it seems plausible to assume that speakers can also mutually adapt the production of segmental timing features after exposure to a dialogue partner.…”

This paper reports on the results of a research investigating whether rhythmic features, in terms of segmental timing properties, are object of speaker’s adjustments after the exposure to a conversational partner. In the context of dialects in contact, this is crucial to understand whether rhythmic attributes may bring about language variation and change. In the context of human-machine interactions, this can benefit the design of spoken dialogues systems to achieve human-likeness. To study rhythmic accommodation, we selected a corpus of pre- and post-dialogue recordings, performed by 18 speakers of Grison and Zurich German (henceforth GRG and ZHG), two Swiss German dialects characterised by noticeable segmental and supra-segmental differences. To quantify rhythmic convergence, we designed three measures based on the segmental timing differences between the two dialects. We compared the Euclidean distances in the three measures between GRG and ZHG speakers in a pair before and after two interactions. Results reveal that dyads members do not significantly shift the production of segmental timing features after the dialogues. Neither linguistic nor social factors can account for the observed accommodation pattern. Cross-dialectal segmental timing differences, captured by the three ratio measures, may be either robust against the influence of interlocutors’ acoustic behaviour or too subtle to be perceived or retained after interactions.

“…We argue that by being attuned to the other's actions, and by regulating self-generated action to engage with those actions, the outcome is a meeting of minds that is a basic, automatic, and non-reflexive understanding of the other's mental transitional states. This dynamic attuning with the other can happen with any behaviour, such as when mimicking gestures and mannerisms, as in the so-called "chameleon effect" (Chartrand & Bargh, 1999), or when copying the intonation and prosodic patterns of the other while reading together (Cerda-Oñate et al, 2021). Also, the reciprocal dialectical exchange does not need to share the same sensory modality (e.g.…”

The argument is developed that autism spectrum disorder can be interpreted economically in terms of a deficit in polymodal integration which limits awareness by babies and infants of the time-contingency for generating their motor responses to information gleaned from seeing the actions of care-givers or hearing them. This gives rise to difficulties with imitation and mental attribution. In order to grasp the root of the problem we consider “primary intersubjectivity” from the standpoint of the Free Energy Principle as developed by Karl Friston. In terms of this principle and concomitant considerations of variational free energy it can be argued that reduction of predictive errors by both early infants and their care-givers is achievable normally by their reciprocal behavioural exchanges. It is impeded when a deficit in a baby’s polymodal integration leads to a delayed time-contingent response. This protracted sensory integration theory of autism can be subsumed under the acronym PSITA.
