Zarlino, one of the most important music theorists XVI century, described minor consonances as ‘sweet’ (dolci) and ‘soft’ (soavi) (Zarlino 1558/1983, in On Modes New Haven, CT: Yale University Press, 1983). Hector Berlioz, his Treatise on Modern Instrumentation Orchestration (London: Novello, 1855), speaks about ‘small acid-sweet voice’ oboe. In line with this tradition describing musical concepts terms taste words, recent empirical studies have found reliable associations between perception...
Virtually every human faculty engage with imitation. One of the most natural and unexplored objects for study mimetic elements in language is onomatopoeia, as it implies an imitative-driven transformation a sound nature into word. Notably, simple sounds are transformed complex strings vowels consonants, making difficult to identify what acoustically preserved this operation. In work we propose definition vocal imitation by which speech that minimize their spectral difference within...
Monitoring respiratory function is essential for assessing the progression of Amyotrophic Lateral Sclerosis (ALS) and planning interventions. Using spirometry data from Radcliff Study (a fully remote, longitudinal, exploratory study with a cohort 67 pALS) we demonstrate that flexible coaching, combined quality control analysis excludes values `0' timepoints failed measurement trials, produces consistent remote results. Our findings indicate home-measured Slow Vital Capacity (SVC) Forced...
Purpose – This paper aims to extend current understanding concerning the cross-modal correspondences between sounds and tastes by introducing new research tools experimental data study associations their reflections music taste. Design/methodology/approach The experiment design addresses multidisciplinary approach using cultural, chemical statistical analysis methods. Findings provides further evidence that exposure “sweet” or “sour” musical pieces influences people’s food-related thinking...
While there is broad consensus about the structural similarities between language and music, comparably less attention has been devoted to semantic correspondences these two ubiquitous manifestations of human culture. We have investigated relations music a narrow bounded domain semantics: words concepts referring taste sensations. In recent work, we found that were consistently mapped musical parameters. Bitter associated with low-pitched continuous (legato), salty characterized by silences...
Song production in songbirds is controlled by a network of nuclei distributed across several brain regions, which drives respiratory and vocal motor systems to generate sound. We built model for birdsong production, whose variables are the average activities different neural populations within these song system. focus on predictions patterns song, because can be easily measured therefore provide validation model. test hypothesis that it possible construct (1) activity an expiratory related...
Abstract Several studies have examined how music may affect the evaluation of food and drink, but vast majority not observed this interaction unfolds in time. This seems to be quite relevant, since both consumer experience food/drink are time-varying nature. In present study we sought fix gap, using Temporal Dominance Sensations (TDS), a method developed record dominant sensory attribute at any given moment time, examine impact on wine taster’s perception. More specifically, assessed same...
A central aspect of the motor control birdsong production is capacity to generate diverse respiratory rhythms, which determine coarse temporal pattern song. The neural mechanisms that underlie this diversity gestures and resulting acoustic syllables are largely unknown. We show patterns highly complex variable organization song in canary (Serinus canaria) can be generated as solutions a simple model describing integration between centers. This example suggests subharmonic behavior play an...
What are the features that impersonators select to elicit a speaker's identity? We built voice database of public figures (targets) and imitations produced by professional impersonators. They one imitation based on their memory target (caricature) another after listening audio (replica). A set naive participants then judged identity similarity pairs voices. Identity was better evoked caricatures replicas were perceived be closer targets in terms similarity. used this data map relevant...
Cervical alignment has become increasingly important in the planning of spine surgery. A relationship between slope T1 (T1S), cervical lordosis (CL), and overall sagittal vertical axis (cSVA) previously been demonstrated, but exact nature this is poorly understood. In study, we derive theoretical empirical equations to better understand how T1S CL affect cSVA. The first equation was developed on a basis using inherent trigonometric relationships spine. By treating as arc circumference, by...
There is a prevailing belief that interruptions using cellular phones during face to interactions may affect severely how people relate and perceive each other. We set out determine this cost quantitatively through an experiment performed in dyads, large audience TEDx event. One of the two participants (the speaker) narrates story vividly. The listener asked deliberately ignore speaker part (for instance, attending their cell-phone). not aware treatment. show total amount attention major...
Abstract Amyotrophic lateral sclerosis (ALS) is a neurodegenerative motor neuron disease that causes progressive muscle weakness. Progressive bulbar dysfunction dysarthria and thus social isolation, reducing quality of life. The Everything ALS Speech Study obtained longitudinal clinical information speech recordings from 292 participants. In subset 120 participants, we measured speaking rate (SR) listener effort (LE), measure severity rated by pathologists recordings. LE intra- inter-rater...
Sound-symbolic word classes are found in different cultures and languages worldwide. These words continuously produced to code complex information about events. Here we explore the capacity of creative language transport multisensory a controlled experiment, where our participants improvised onomatopoeias from noisy moving objects audio, visual audiovisual formats. We that consonants communicate movement types (slide, hit or ring) mainly through manner articulation vocal tract. Vowels shapes...
In this work we study a simple model of voiced sound production. We analyze contributions that the qualitative theory dynamical systems can make to analysis and synthesis human speech.
In this work we analyze the solutions of a simple system coupled phase oscillators in which connectivity is learned dynamically. The model inspired by process learning birdsongs oscine birds. An oscillator acts as generator basic rhythm and drives slave are responsible for different motor actions. driving signal arrives at each driven through two pathways. One them direct pathway. other one reinforcement pathway, delayed. coupling coefficients between ones evolve time following Hebbian-like...
Horneros (Furnarius Rufus) are South American birds well known for their oven-looking nests and ability to sing in couples. Previous work has analyzed the rhythmic organization of duets, unveiling a mathematical structure behind songs. In this we analyze detail an extended database duets. The rhythms songs compatible with dynamics presented by wide class dynamical systems: forced excitable systems. Compatible nonlinear rule, build biologically inspired model how neural anatomical elements...
In this work we study the generation of respiratory patterns by oscine birds. We present a model capable generating realistic patterns, during normal respiration and song production. The accounts for interaction between neural nuclei air sac dynamics. performed experiments in vivo order to test predictions model, measuring pressure canaries (Serinus canaria).
The folds of the brain offer a particular challenge for subarachnoid vascular grid. primitive blood vessels that occupy this space, when is flat, have to adapt an everchanging geometry while constructing efficient network. Surprisingly, result non-redundant arterial system easily challenged by acute occlusions. Here, we generalize optimal network building principles flat surface growing into folded configuration and generate ideal middle cerebral artery (MCA) can be directly compared with...
In this work, we revisit the path that has been travelled during last few years towards modelling of avian vocal organ, syrinx, using numerical and theoretical techniques from bifurcation theory as analysing tools present experimental support for models. This fruitful perspective allowed retracing many acoustic features syllables to intrinsic properties thereby relocating bird phonatory organ role a mere instrument nervous system central source complex acoustical behaviour.
Current models of human vocal production that capture peripheral dynamics in speech require large dimensional measurements the neural activity, which are mapped into equally complex motor gestures. In this work we present a description for vowels as points discrete low-dimensional space. We monitor 3 at oral cavity using Hall-effect transducers and magnets, describing resulting signals during normal utterances terms active/inactive patterns allow robust vowel classification an abstract...
The singing by songbirds is a most convincing example in the animal kingdom of functional lateralization brain, feature usually associated with human language. Lateralization expressed as one or both bird's sound sources being active during vocalization. Normal songs require high coordination between vocal organ and respiratory activity, which bilaterally symmetric. Moreover, physical neural substrate used to produce song lack obvious asymmetries. In this work we show that complex...
The sounds of all languages are described by a finite set symbols, which extracted from the continuum produced vocal organ. How discrete phonemic identity is encoded in continuous movements producing speech remains an open question for experimental phonology. In this work, assessed using Hall-effect transducers and magnets -mounted on tongue, lips jaw- to track kinematics oral tract during vocalization vowel-consonant-vowel structures. Using threshold strategy, time traces were converted...
