Résumé :

Most studies investigating neural representations of species-specific vocalizations in non-human primates and other species have involved studying neural responses to vocalization tokens. One limitation of such approaches is the difficulty in determining which acoustical features of vocalizations evoke neural responses. Traditionally used filtering techniques are often inadequate in manipulating features of complex vocalizations. Furthermore, the use of vocalization tokens cannot fully account for intrinsic stochastic variations of vocalizations that are crucial in understanding the neural cod

Objectives: This study investigated the relationship of phonological characteristics between early vocalizations at 6-8 months, 12-14 months, and words at 18-20 months.

Résumé :

Little is known about sensory-motor interaction in the auditory cortex of primates at the level of single neurons and its role in supporting vocal communication. The present study investigated single-unit activities in the auditory cortex of a vocal primate, the common marmoset ( Callithrix jacchus), during self-initiated vocalizations. We found that 1) self-initiated vocalizations resulted in suppression of neural discharges in a majority of auditory cortical neurons. The vocalization-induced inhibition suppressed both spontaneous and stimulus-driven discharges. Suppressed units responded poo

Résumé :

Abstract The main argument for the unreliability of the Tiberian vocalization in Targum manuscripts of western origin is the inconsistency with which the vocalization signs are applied. The author argues that in certain manuscripts this inconsistency is the result of a non-Tiberian vocalization system which uses the Tiberian vocalization signs, the so-called Palestino-Tiberian vocalization system. A passage from an Ashkenazic Targumic manuscript with Palestino-Tiberian vocalization is examined and its 'inconsistencies' are explained in light of similar vocalizations in manuscripts of Rabbinic

Résumé :

Auditory-vocal interaction, the modulation of auditory sensory responses during vocal production, is an important but poorly understood neurophysiological phenomenon in nonhuman primates. This sensory-motor processing has important behavioral implications for self-monitoring during vocal production as well as feedback-mediated vocal control for both animals and humans. Previous studies in marmosets have shown that a large portion of neurons in the auditory cortex are suppressed during self-produced vocalization but have primarily focused on a single type of isolation vocalization.

The difference in treatment of vocal features in Oscines and Suboscines passerine birds characterizes a large portion of the current studies on their taxonomy. In the former taxon, vocalization is supposed to be molded by learning, and consequently is not regarded as taxonomically informative. In the latter, a strong emphasis is given to vocalization because it supposedly reflects the genetic structure of populations. This paper reviews the various assumptions related to this difference in treatment, including the overestimation of the vocal characters in suboscine alpha taxonomy due to the al

AbstractThere are many studies on how songbirds develop song production, but few on how songbirds develop appropriate responses to conspecific vocalizations. The black-capped chickadee, Parus atricapillus, produces a vocalization, the 'squawk', that stimulates gaping in nestlings during feeding. To determine whether nestlings gape selectively at the squawk, playbacks of several conspecific vocalizations plus a heterospecific vocalization were presented to nestlings within natural nests. A preference for the squawk did not appear until day 2-3 and then steadily increased, until by day 11-13, ne

Résumé :

In this study, we examined the role of the ventrolateral prefrontal cortex in encoding communication stimuli. Specifically, we recorded single-unit responses from the ventrolateral prefrontal cortext (vlPFC) in awake behaving rhesus macaques in response to species-specific vocalizations. We determined the selectivity of vlPFC cells for 10 types of rhesus vocalizations and also asked what types of vocalizations cluster together in the neuronal response. The data from the present study demonstrate that vlPFC auditory neurons respond to a variety of species-specific vocalizations from a previousl

Leveraging data acquired using a 160-element coherent hydrophone array deployed in the Norwegian and Barents Seas during spring 2014, and the passive ocean acoustic waveguide remote sensing (POAWRS) technique is employed to enable instantaneous wide-area monitoring of marine mammal vocalizations over expanses exceeding 100 km in diameter. The vocalization behavior of diverse marine mammal species including Fin, Humpback, Minke, Sperm, and Beluga whales are analyzed, quantifying time-frequency characteristics and call patterns from their vocalization signals present in high-resolution beamforme

Résumé :

Vocal signals are a common communication tool used to recognize different individuals, advertise fertile phases or discriminate amongst potential mates. Therefore, a thorough understanding of vocal repertoires forms the basis for investigating the role of acoustic signaling in the sexual and social behavior of any animal. Red pandas (Ailurus fulgens) are classified as a vulnerable species and have declined by as much as 40% over the past 50 years in China. Adult red pandas are known to call frequently during mating and aggressive encounters; however, no quantitative description of their vocali

Résumé :

Hearing one's own voice is important for regulating ongoing speech and for mapping speech sounds onto articulator movements. However, it is currently unknown whether attention mediates changes in the relationship between motor commands and their acoustic output, which are necessary as growth and aging inevitably cause changes to the vocal tract. In this study, participants produced vocalizations while they heard their vocal pitch persistently shifted downward one semitone in both single- and dual-task conditions. During the single-task condition, participants vocalized while passively viewing

Purpose To better enable communication among researchers, clinicians, and caregivers, we aimed to assess how untrained listeners classify early infant vocalization types in comparison to terms currently used by researchers and clinicians. Method Listeners were caregivers with no prior formal education in speech and language development. A 1st group of listeners reported on clinician/researcher-classified vowel, squeal, growl, raspberry, whisper, laugh, and cry vocalizations obtained from archived video/audio recordings of 10 infants from 4 through 12 months of age.

Résumé :

Over the last few years, an increasing number of studies have aimed to gain more insight into the field of animal emotions. In particular, it is of interest to determine whether animals can cross-modally categorize the emotions of others. For domestic animals that share a close relationship with humans, we might wonder whether this cross-modal recognition of emotions extends to humans, as well. In this study, we tested whether horses could recognize human emotions and attribute the emotional valence of visual (facial expression) and vocal (non-verbal vocalization) stimuli to the same perceptua

Rhythm is an essential component of human speech and music but very little is known about its evolutionary origin and its distribution in animal vocalizations.

The intervals between element onsets were used to fit the rhythm for each individual. For echolocation call sequences, we expected rhythm frequencies around 6–24 Hz, corresponding to the wingbeat in S. bilineata which is strongly coupled to echolo
