“…This may be due in part to the challenge of working with single word stimuli, which are phonetically impoverished compared to full sentences. However, recent work, including that of Francis and Driscoll (2007), González and McLennan (2007), and the present study, has been more consistent in revealing a rightward specialization for talker-specific processing, thus providing converging evidence with results from neuroimaging and neuropsychology for the specialization of right-hemisphere neural circuitry for such tasks. The converging results from these studies may also lend empirical support to models that attribute person identification generally to neural systems situated in the right hemisphere.…”

Humans are remarkably adept at identifying individuals by the sound of their voice, a behavior supported by the nervous system's ability to integrate information from voice and speech perception. Talker-identification abilities are significantly impaired when listeners are unfamiliar with the language being spoken. Recent behavioral studies describing the language-familiarity effect implicate functionally integrated neural systems for speech and voice perception, yet specific neuroscientific evidence demonstrating the basis for such integration has not yet been shown. Listeners in the present study learned to identify voices speaking a familiar (native) or unfamiliar (foreign) language. The talker-identification performance of neural circuitry in each cerebral hemisphere was assessed using dichotic listening. To determine the relative contribution of circuitry in each hemisphere to ecological (binaural) talker identification abilities, we compared the predictive capacity of dichotic performance on binaural performance across languages. We found listeners' right-ear (left hemisphere) performance to be a better predictor of overall accuracy in their native language than a foreign one. The enhanced predictive capacity of the classically language-dominant left-hemisphere on overall talker-identification accuracy demonstrates functionally integrated neural systems for speech and voice perception during natural talker identification.

“…Training to categorize non-phonemic auditory signals also enhanced fMRI activation in left posterior superior temporal sulcus (Liebenthal et al, 2010). Inversely, training to associate a brief temporal distinction (along the same dimension that distinguishes /d/ from /t/) to talker identity, rather than speech categories, can cause the opposite shift from left-to right-lateralization (Francis and Driscoll, 2006). Brain morphometric studies also support a critical role of the left temporal area for efficient language learning.…”

During the past ten years, research using Near-infrared Spectroscopy (NIRS) to study the developing brain has provided groundbreaking evidence of brain functions in infants. This paper presents a theoretically oriented review of this wealth of evidence, summarizing recent NIRS data on language processing, without neglecting other neuroimaging or behavioral studies in infancy and adulthood. We review three competing classes of hypotheses (i.e. signal-driven, domain-driven, and learning biases hypotheses) regarding the causes of hemispheric specialization for speech processing. We assess the fit between each of these hypotheses and neuroimaging evidence in speech perception and show that none of the three hypotheses can account for the entire set of observations on its own. However, we argue that they provide a good fit when combined within a developmental perspective. According to our proposed scenario, lateralization for language emerges out of the interaction between pre-existing left-right biases in generic auditory processing (signal-driven hypothesis), and a left-hemisphere predominance of particular learning mechanisms (learning-biases hypothesis). As a result of this completed developmental process, the native language is represented in the left hemisphere predominantly. The integrated scenario enables to link infant and adult data, and points to many empirical avenues that need to be explored more systematically.

“…This supports a model of the organization of voice processing in which speech and identity information are processed in partially dissociated cortical regions. Francis & Driscoll (2006) trained their subjects to use voice onset time (VOT) to cue speaker identity. Successful learners showed shorter response times for stimuli presented only to the left ear than for those presented only to the right.…”

Structural and functional asymmetries are present in many regions of the human brain responsible for motor control, sensory and cognitive functions and communication. Here, we focus on hemispheric asymmetries underlying the domain of social perception, broadly conceived as the analysis of information about other individuals based on acoustic, visual and chemical signals. By means of these cues the brain establishes the border between 'self ' and 'other', and interprets the surrounding social world in terms of the physical and behavioural characteristics of conspecifics essential for impression formation and for creating bonds and relationships. We show that, considered from the standpoint of single-and multi-modal sensory analysis, the neural substrates of the perception of voices, faces, gestures, smells and pheromones, as evidenced by modern neuroimaging techniques, are characterized by a general pattern of right-hemispheric functional asymmetry that might benefit from other aspects of hemispheric lateralization rather than constituting a true specialization for social information.
