Beyond speech: Exploring diversity in the human voice

iScience, Journal Year: 2023, Volume and Issue: 26(11), P. 108204 - 108204

Published: Oct. 14, 2023

Humans have evolved voluntary control over vocal production for speaking and singing, while preserving the phylogenetically older system of spontaneous nonverbal vocalizations such as laughs screams. To test systematic acoustic differences between these domains, we analyzed a broad, cross-cultural corpus representing 2 h speech, vocalizations. We show that, speech is relatively low-pitched tonal with mostly regular phonation, singing especially vary enormously in pitch often display harsh-sounding, irregular phonation owing to nonlinear phenomena. The evolution complex supralaryngeal articulatory spectro-temporal modulation has been critical yet not significantly constrained laryngeal source modulation. In contrast, articulation very limited vocalizations, which predominantly contain minimally articulated open vowels rapid temporal roughness range. infer that works best conveying affect, filter mainly facilitates semantic communication.

Biological principles for music and mental health

Abstract Efforts to integrate music into healthcare systems and wellness practices are accelerating but the biological foundations supporting these initiatives remain underappreciated. As a result, music-based interventions often sidelined in medicine. Here, I bring together advances research from neuroscience, psychology, psychiatry bridge music’s specific human biology with its therapeutic applications. The framework propose organizes neurophysiological effects of around four core elements musicality: tonality, rhythm, reward, sociality. For each, review key concepts, bases, evidence clinical benefits. Within this framework, outline strategy increase impact on health based standardizing treatments their alignment individual differences responsivity musical elements. that an integrated understanding musicality—describing each element’s functional origins, development, phylogeny, neural bases—is critical advancing rational applications mental wellness.

From Perception to Pleasure

Oxford University Press eBooks, Journal Year: 2023, Volume and Issue: unknown

Abstract How does perception of abstract tonal patterns—music—lead to the pleasure we experience from these sounds? The answer presented in this book is that music arises interactions between cortical loops enable processing sound patterns and subcortical circuits responsible for reward valuation. auditory cortex its ventral-stream connections encode acoustical features their relationships, maintain them working memory, form internal representations statistical which predictions are made about how evolve time. Disruption pathway leads amusia. dorsal stream allows sensory-motor transformations, production, metrical representation, leading when events will occur.

Audio‐visual concert performances synchronize audience's heart rates

Abstract People enjoy engaging with music. Live music concerts provide an excellent option to investigate real‐world experiences, and at the same time, use neurophysiological synchrony assess dynamic engagement. In current study, we assessed engagement in a live concert setting using of cardiorespiratory measures, comparing inter‐subject, stimulus–response, correlation, phase coherence. As might be enhanced by seeing musicians perform, presented audiences audio‐only (AO) audio‐visual (AV) piano performances. Only correlation measures were above chance level. time‐averaged across conditions, AV performances evoked higher inter‐subject heart rate (ISC‐HR). However, averaged pieces did not correspond self‐reported On other hand, time‐resolved analyses show that synchronized deceleration‐acceleration (HR) patterns, typical “orienting response” (an index directed attention), occurred within salient events section boundaries.

CoVox: A dataset of contrasting vocalizations

Abstract The human voice is remarkably versatile and can vary greatly in sound depending on how it used. An increasing number of studies have addressed the differences similarities between singing speaking voice. However, finding adequate stimuli material that at same time controlled ecologically valid challenging, most datasets lack variability terms vocal styles performed by Here, we describe a curated stimulus set vocalizations where 22 female singers melody excerpts three contrasting (as lullaby, as pop song, an opera aria) spoke text aloud two if to adult or infant). All productions were made with songs’ original lyrics, Brazilian Portuguese, a/lu/sound.

Virtual Universals and Creativity: A New Approach to Music Cognition

Music & Science, Journal Year: 2025, Volume and Issue: 8

Published: May 1, 2025

If music is so varied, how do we understand it? Is there anything universal about And if not, can be a cognitive science of Radically limiting examples they fit certain frameworks but then calling everything else an exception not helpful. We propose redefinition that based on specific features rather as creative experimentation with what term “virtual universals.” These are universals exert force even when actualized or sounded. Our argument has applicability beyond the domain music; in principle, ideas this paper could applied to any human behavior.

Auditory-motor synchronization and perception suggest partially distinct time scales in speech and music

Communications Psychology, Journal Year: 2024, Volume and Issue: 2(1)

Published: Jan. 3, 2024

Speech and music might involve specific cognitive rhythmic timing mechanisms related to differences in the dominant structure. We investigate influence of different motor effectors on rate-specific processing both domains. A perception a synchronization task involving syllable piano tone sequences typically associated with speech (whispering) (finger-tapping) were tested at slow (~2 Hz) fast rates (~4.5 Hz). Although performance was generally better rates, exhibited rate preferences. Finger-tapping advantaged compared whispering but not faster being effector-dependent slow, highly correlated rates. Perception predicted by general finger-tapping component. Our data suggests partially independent for music, possibly differential recruitment cortical circuitry.

Voice preferences are an integral part of interpersonal interactions and shape how people connect with each other. While a large number studies have investigated the mechanisms behind (speaking) voice attractiveness, very little research was dedicated to other types vocalizations. In this Registered Report, we proposed investigate integrative approach. To end, used newly recorded validated stimulus set contrasting vocalizations by 22 highly trained female singers speaking singing same material (in Brazilian Portuguese) in styles (sung as lullaby, pop song or opera aria; spoken aloud if directed adult audience infant). We asked 62 participants rate these terms much they liked them; compared amount shared taste (that is, agreed their preferences) across styles. found idiosyncratic all Our predictions concerning were not confirmed: although higher for lullaby than singing, it unexpectedly operatic infant-directed adult-directed speech.

Lateralisation key processes underlying their perception has been related both to the distinct sensitivity low-level spectrotemporal acoustic features top-down attention. However, interplay between bottom-up needs be clarified. In present study, we investigated contribution acoustics attention melodies or sentences lateralisation in fMRI functional network topology. We used sung speech stimuli selectively filtered temporal spectral modulation domains with crossed balanced verbal melodic content. Perception decreased degradation information, whereas degradation. Applying graph theoretical metrics on connectivity matrices, found that local clustering, reflecting specialisation, linearly increased when cues crucial for task goal were incrementally degraded. These effects occurred a bilateral fronto-temporo-parietal processing temporally degraded right auditory regions spectrally melodies. contrast, global topology remained stable across conditions. findings suggest partially depends an goals under attentional demands.
