  • discriminate
  • Developmentalists therefore make inferences about how preverbal children learn to discriminate speech sounds that they heard in their environments. (wikiversity.org)
  • The problem is for example seen in tasks where the individual has to manipulate sound segments in the spoken language, read non-words, rapidly name pictures and digits, keep verbal material in short-term memory, and categorize and discriminate sound contrasts in speech perception. (diva-portal.org)
  • Infants are born with a preference for listening to speech over non-speech, and with a set of perceptual sensitivities that enable them to discriminate most of the speech sound differences used in the world's languages, thus preparing them to acquire any language. (grantome.com)
  • Infants will be tested at 6-months, an age at which they can still discriminate non-native speech sounds, and at 10-months, an age after they begin to fail. (grantome.com)
  • In addition, although the dyslexic subjects were able to label and discriminate the synthetic speech continua, they did not necessarily use the acoustic cues in the same manner as normal readers, and their overall performance was generally less accurate. (asha.org)
  • cues
  • Auditory-visual facilitation was quantified with response time and accuracy measures and the N1/P2 ERP waveform response as a function of changes in audibility (manipulation of the acoustic environment by testing a range of signal-to-noise ratios) and content of optic cue (manipulation of the types of cues available, e.g., speech, nonspeech-static, or non-speech-dynamic cues). (illinois.edu)
  • ERP measures showed effects of reduced audibility (slower latency, decreased amplitude) for both types of facial motion, i.e., speech and non-speech dynamic facial optic cues, compared to measures in quiet conditions. (illinois.edu)
  • Research and (re)habilitation therapies for speech perception in noise must continue to emphasize the benefit of associating and integrating auditory and visual speech cues. (illinois.edu)
  • This line of research investigates the role of visual input, particularly facial cues, in speech segmentation. (wordpress.com)
  • Speech segmentation research has focused primarily on the nature and availability of auditory word boundary cues (e.g. stress, phonotactics, distributional properties). (wordpress.com)
  • Visual speech segmentation: Using facial cues to locate word boundaries in continuous speech. (wordpress.com)
  • contrasts
  • The purpose of the present study was twofold: 1) to compare the hierarchy of perceived and produced significant speech pattern contrasts in children with cochlear implants, and 2) to compare this hierarchy to developmental data of children with normal hearing. (mendeley.com)
  • auditory and visual
  • N1 latency was faster with both types of facial motion tested in this experiment, but N1 amplitude was decreased only with concurrent presentation of auditory and visual speech. (illinois.edu)
  • As normal speech recognition is affected by both the auditory input and the visual lip movements of the speaker, we investigated the efficiency of audio and visual integration in an older population by manipulating the relative reliability of the auditory and visual information in speech. (frontiersin.org)
  • vowels
  • As they are 6 months old, they are introduced to statistical learning (distributional frequencies) and they have preference to language-specific perception for vowels. (wikiversity.org)
  • and 5) the hierarchy in speech pattern contrast perception and production was similar between the implanted and the normal-hearing children, with the exception of the vowels (possibly because of the interaction between the specific information provided by the implant device and the acoustics of the Hebrew language). (mendeley.com)
  • hypothesis
  • The purpose of this study was to test the hypothesis by investigating oscillatory dynamics from ongoing EEG recordings whilst participants passively viewed ecologically realistic face-speech interactions in film. (diva-portal.org)
  • In Aim 1, we implement a computational model (an attractor network, with interconnectivity among units serving producflon, percepflon, and orthography) in order to concretely formulate the Articulatory Integration Hypothesis (AIH): co-development of speech production, percepflon, and reading should result in pervasive, interactive linkages that shape representations and performance in each domain. (grantome.com)
  • cortical
  • Functional changes in inter- and intra-hemispheric cortical processing underlying degraded speech perception. (nih.gov)
  • Our findings demonstrate changes in the functional asymmetry of cortical speech processing during adverse acoustic conditions and suggest that "cocktail party" listening skills depend on the quality of speech representations in the left cerebral hemisphere rather than compensatory recruitment of right hemisphere mechanisms. (nih.gov)
  • Cortical Activation Patterns Correlate with Speech Understanding After Cochlear Implantation. (semanticscholar.org)
  • Other theories have proposed that articulatory gestures form the informational basis not just for speech producflon, but also speech perception, either as the basis for special purpose cortical mechanisms (Liberman &Mattingly, 1985), or because as-yet undiscovered information in the speech signal directly specifles articulation (Fowler, 1986). (grantome.com)
  • sensory
  • Results indicated that cross-communications between the frontal lobes, intraparietal associative areas and primary auditory and occipital cortices are specifically enhanced during natural face-speech perception and that phase synchronisation mediates the functional exchange of information associated with face-speech processing between both sensory and associative regions in both hemispheres. (diva-portal.org)

(auditory.org)
  • Some of the age-related decline in speech perception can be accounted for by peripheral sensory problems but cognitive aging can also be a contributing factor. (ejao.org)
  • Here, it is proposed that the earliest developing sensory system - likely somatosensory in the case of speech, including somatosensory feedback from oral-motor movements that are first manifest in the fetus, provides an organization on which auditory speech can build once the peripheral auditory system comes on-line by 22 weeks gestation.

  • Universal literacy, differences between spoken and written language, models of perception and processing, and implications of natural acquisition of reading. (coursera.org)
  • temporal
  • During the articulation of speech the sound made by the speaker is accompanied by the congruent temporal and spatial visual information offered through the speaker's jaw, tongue, and lip movements, referred to as the viseme. (frontiersin.org)
  • Temporal jitter disrupts speech intelligibility: a simulation of auditory aging. (semanticscholar.org)
  • Participants made temporal order judgments (TOJs) regarding whether the speech-sound or the visual-speech gesture occurred first, for video clips presented at various different stimulus onset asynchronies. (ox.ac.uk)
  • empirical
  • The comprehensive computaflonal model and cutting-edge empirical investigaflons in Project II are essential in developing a deeper understanding of perception-producflon-reading links, which will provide new constraints on theories of language development and new insights into the phonological basis of reading. (grantome.com)
  • articulation
  • In this framework, articulation is not a form of special internal knowledge;it is just additional information available to the system that may especially facilitate speech percepflon under noisy or ambiguous condiflons. (grantome.com)
  • articulatory
  • 2003). This shows that excitability of the articulatory motor cortex is enhanced during speech perception. (ox.ac.uk)
  • Our recent study showed that TMS-induced disruption of the articulatory motor cortex suppresses automatic EEG responses to changes in speech sounds, but not to changes in piano tones (Möttönen et al. (ox.ac.uk)
  • Using TMS, we found that excitability of the articulatory motor cortex was higher during observation of known speech (English) than unknown speech (Hebrew) or non-speech mouth movements in both native and non-native speakers of English (Swaminathan et al. (ox.ac.uk)
  • unfamiliar speech
  • In contrast, the Dutch subtitles did not provide this teaching function, and, because they told the viewer what the characters in the film meant to say, the Dutch subtitles may have drawn the students' attention away from the unfamiliar speech. (innovations-report.com)
  • experiments
  • They were also aware of the association between simplified characters and the Beijing Mandarin dialect and this association was activated during the speech perception and production experiments of this dissertation. (rice.edu)
  • The first two experiments focused on the effect of glottal waveform in the perception of talker identity. (ed.gov)
  • Experiments three (20 subjects) and four (13 subjects) assessed the relative contributions of glottal waveform, fundamental frequency, and formant spacing to the perception of talker identity. (ed.gov)
  • variation
  • The effect of character variation on speech production was not as straightforward as that in perception. (rice.edu)
  • however, when taking the speaker's attitude towards different varieties of characters into consideration, personal preferences toward the varieties of characters may lead to a stylistic and intentional variation in speech production of retroflex sibilants. (rice.edu)
