The human ability to follow speech gestures through the visual modality is a core component of speech perception. Remarkably, speech can be perceived not only by the ear and by the eye but also by the hand, with speech gestures felt from manual tactile contact with the speaker’s face. In the present study, early crossmodal interactions were investigated by comparing early auditory evoked potent...

ABSTRACT Objective: to analyze speech perception in normally hearing adults when listening silence and with different types of noise. Methods: 40 individuals both sexes, aged 18 45 years, participated the study. Speech was assessed Lists Sentences Portuguese test, without a competing noise speech-spectrum, babble, cocktail party A mixed-effects linear regression model 95% confidence interval we...

Perception and Production of Syllable-Initial English [r] and [1] by English and Japanese Speakers by Elzbieta B. Slawinski The Psychology Department, The University of Calgary Introduction. V arious studies have investigated a contribution of multiple acoustic cues to the perceptual distinction of [r-1] phonetic contrast in English (e.g., Dalston, 1975; Underbakke and Polka, 1988). The results...

The mechanisms and functional anatomy underlying the early stages of speech perception are still not well understood. One way to investigate the cognitive and neural underpinnings of speech perception is by investigating patients with speech perception deficits but with preserved ability in other domains of language. One such case is reported here: patient NL shows highly impaired speech percep...

objectives: auditory perception or hearing ability is critical for children in acquisition of language and speech hence hearing loss has different effects on individuals’ linguistic perception, and also on their functions. it seems that deaf people suffer from language and speech impairments such as in perception of complex linguistic constructions. this research was aimed to study the percepti...

Understanding others’ speech while individuals simultaneously produce utterances implies neural competition and requires specific mechanisms for a resolution given that previous studies proposed opposing signal dynamics both processes in the auditory cortex (AC). We here used neuroimaging humans to investigate this by lateralized stimulations with other samples ipsilateral or contralateral feed...

The study described in this paper is an attempt to answer the question ‘Which aspect of speech perception is altered by linguistic experience and how this alteration is done?’ As Strange and Jenkins stated, “[t]he knowledge of a language possessed by a normal adult is a product of many years of exposure to a specific language environment” (1978: 125). Therefore, if linguistic knowledge influenc...
