“…Although numerous studies have mixed the mouth position in a fully frontal direction for loud speech, head and mouth movements are not stationary, as explained by Tiede et al [ 39 ]. These types of movements can structure the discourse, indicate deixis and multiple lexical connotations.…”

As evidenced by the worldwide pandemic, respiratory infectious diseases and their airborne transmission must be studied to safeguard public health. This study focuses on the emission and transport of speech-generated droplets, which can pose risk of infection depending on the loudness of the speech, its duration and the initial angle of exhalation. We have numerically investigated the transport of these droplets into the human respiratory tract by way of a natural breathing cycle in order to predict the infection probability of three strains of SARS-CoV-2 on a person who is listening at a one-meter distance. Numerical methods were used to set the boundary conditions of the speaking and breathing models and large eddy simulation (LES) was used for the unsteady simulation of approximately 10 breathing cycles. Four different mouth angles when speaking were contrasted to evaluate real conditions of human communication and the possibility of infection. Breathed virions were counted using two different approaches: the breathing zone of influence and direction deposition on the tissue. Our results show that infection probability drastically changes based on the mouth angle and the breathing zone of influence overpredicts the inhalation risk in all cases. We conclude that to portray real conditions, the probability of infection should be based on direct tissue deposition results to avoid overprediction and that several mouth angles must be considered in future analyses.

“…Just as a kinetic description of overt dance movements revealed how musical rhythms were embodied, kinetic properties of co-speech movements are also relevant for their temporal relation to continuous speech (Tuite, 1993). As noted above, speaking often occurs with movement of the head (Tiede, et al, 2019), and the degree of physical impulses through manual gesture correlates with the magnitude of concurrent head movements (Pouw et al, 2022). We suggest that the correlated nature of head and arm movements is not a coincidence, but rather arises because co-speech movements are designed to create a mechanical stimulus detectable by the vestibular periphery.…”

The temporal signatures that characterize speech—especially its prosodic qualities—are observable in the movements of the hands and bodies of its speakers. A neurobiological account of these prosodic rhythms is thus likely to benefit from insights on the neural coding principles underlying co-speech gestures. Here we consider a role for the information processing capacity of the vestibular system, a sensory system that encodes movements of the body, in the neural representation of prosody. Careful review of the vestibular system’s functional organization as a hierarchical and predictive system, its relevance for rhythmic sound sequences, dynamic attention, and its involvement in vocalization suggests vestibular codes may be important for the neural tracking of speech. As the kinematics and time course of co-speech movements mirror prosodic fluctuations in spoken prosody, we argue that the vestibular system helps encode and decode these prosodic features in multimodal discourse and possibly during auditory speech processing alone.

“…The EMA signal was sampled at 400 Hz. After recording, EMA data were post-processed in two steps (for more details on the method, see Tiede et al, 2019b). As a first step, movement of the head was corrected with MATLAB software using the four reference coils glued on the nose, upper incisor, and behind both ears.…”

Acoustic characteristics, lingual and labial articulatory dynamics, and ventilatory behaviors were studied on a beatboxer producing twelve drum sounds belonging to five main categories of his repertoire (kick, snare, hi-hat, rimshot, cymbal). Various types of experimental data were collected synchronously (respiratory inductance plethysmography, electroglottography, electromagnetic articulography, and acoustic recording). Automatic unsupervised classification was successfully applied on acoustic data with t-SNE spectral clustering technique. A cluster purity value of 94% was achieved, showing that each sound has a specific acoustic signature. Acoustical intensity of sounds produced with the humming technique was found to be significantly lower than their non-humming counterparts. For these sounds, a dissociation between articulation and breathing was observed. Overall, a wide range of articulatory gestures was observed, some of which were non-linguistic. The tongue was systematically involved in the articulation of the explored beatboxing sounds, either as the main articulator or as accompanying the lip dynamics. Two pulmonic and three non-pulmonic airstream mechanisms were identified. Ejectives were found in the production of all the sounds with bilabial occlusion or alveolar occlusion with egressive airstream. A phonetic annotation using the IPA alphabet was performed, highlighting the complexity of such sound production and the limits of speech-based annotation.
