“…HS speakers synchronize their speech to an external rhythm, whereas LS speakers do not (Assaneo et al, 2019). Also consistent with findings from the general population (Rimmele et al, 2022), we found that differences in synchronization were related to musical training: HS individuals demonstrated more years of musical training than LS individuals. Interestingly, there were no differences between stutterers and non-stutterers on speech-specific SMS based on the SSS test, which is in line with Max and Yudman (2003).…”

“…Years of musical training is one of the items of the subscale and was the parameter explored in this study. Previous work shows that, in the general population, music experience differs between HS and LS, with the former displaying more years of musical training overall (Assaneo et al, 2019;Rimmele et al, 2022). In addition, musical training is related to the microstructural properties of white matter tracts connecting auditory to motor regions, including the arcuate fasciculus (Halwani et al, 2011), such that HS and LS exhibit differences in this white matter tract (Assaneo et al, 2019).…”

Stuttering is a neurodevelopmental speech disorder associated with motor timing that differs from non-stutterers. While neurodevelopmental disorders impacted by timing are associated with compromised auditory-motor integration and interoception, the interplay between those abilities and stuttering remains unexplored. Here, we studied the relationships between speech auditory-motor synchronization (a proxy for auditory-motor integration), interoceptive awareness, and self-reported stuttering severity using remotely delivered assessments. Results indicate that in general, stutterers and non-stutterers exhibit similar auditory-motor integration and interoceptive abilities. However, while speech auditory-motor synchrony (i.e., integration) and interoceptive awareness were not related, speech synchrony was inversely related to the speaker’s perception of stuttering severity as perceived by others, and interoceptive awareness was inversely related to self-reported stuttering impact. These findings support claims that stuttering is a heterogeneous, multi-faceted disorder such that uncorrelated auditory-motor integration and interoception measurements predicted different aspects of stuttering, suggesting two unrelated sources of timing differences associated with the disorder.

“…The authors reported that auditory-motor synchronization is characterized by a bimodal distribution in the population, classifying individuals into high versus low synchronizers. (The rejection of unimodality has been previously shown with large sample sizes(40, see also:,46). ) Importantly, in addition to superior behavioral synchronization, high synchronizers have stronger structural and functional connectivity between auditory and speech motor cortices (see 40,Figure 3A and B).…”

When speech is too fast, the tracking of the acoustic signal along the auditory pathway deteriorates, leading to suboptimal speech segmentation and decoding of speech information. Thus, speech comprehension is limited by the temporal constraints of the auditory system. Previous research suggests that individual differences in auditory-motor coupling strength might shape such temporal constraints. In two behavioral experiments, we characterize individual differences in the comprehension of naturalistic speech as function of the individual coupling strength between the auditory and motor systems, and the preferred frequencies of the systems. As expected, speech comprehension declined at higher rates. Importantly, both, higher auditory-motor coupling and higher spontaneous speech motor production rates were related to better speech-comprehension performance. Furthermore, performance increased with higher linguistic sentence predictability (using a recurrent neural network) -particularly at higher speech rates and for individuals with high auditory-motor coupling strength- and with participants' higher working memory capacity (Digit Span). These findings support the notion of an individual preferred auditory regime that allows for optimal auditory (speech) processing. Crucially, we provide evidence for a model that assigns a central role to motor-system-dependent individual flexibility in continuous speech comprehension.

Speech and music signals show rhythmicity in their temporal structure with slower rhythmic rates in music than in speech. Speech processing has been related to brain rhythms in the auditory and motor cortex at around 4.5 Hz, while music processing has been associated to motor cortex activity at around 2 Hz reflecting the temporal structures in speech and music. In addition, slow motor cortex brain rhythms were suggested to be central for timing in both domains. It thus remains unclear if domain-general or frequency specific mechanisms are driving speech and music processing. Additionally, for speech processing, auditory-motor cortex coupling and perception-production synchronization at 4.5 Hz have been related to enhanced auditory perception in various tasks. However, it is unknown whether this effect generalizes to synchronization and perception in music at distinct optimal rates. Using a behavioral protocol, we investigate whether (1) perception-production synchronization shows distinct optimal rates for speech and music; (2) optimal rates in perception are predicted by synchronization strength at different time scales. A perception task involving speech and music stimuli and a synchronization task using tapping and whispering were conducted at slow (~2 Hz) and fast rates (~4.5 Hz). Results revealed that synchronization was generally better at slow rates. Importantly, for slow but not for fast rates, tapping showed superior performance when compared to whispering, suggesting domain-specific rate preferences. Accordingly, synchronization performance was highly correlated across domains only at fast but not at slow rates. Altogether, perception of speech and music were optimal at different timescales, and predicted by auditory-motor synchronization strength. Our data suggests different optimal time scales for music and speech processing with partially overlapping mechanisms.
