Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Integration of visual and auditory speech cues is a process used by listeners in compromised listening situations, as well as in normal environments, as exemplified by the McGurk effect (McGurk and McDonald, 1976). Audio-visual integration of speech appears to be a skill independent of the ability to process auditory or visual speech cues alone. Grant and Seitz (1998) argued for independence of this process based on their findings that integration abilities could not be predicted from auditory-only or visual-only performance. Gariety (2009) and James (2009) further supported this argument by training listeners in the auditory-only modality with degraded speech syllables, then testing those listeners in the auditory-only, visual-only, and audio-visual conditions. Their results showed an increase in auditory-only performance, but no improvement in integration. Recently, DiStefano (2010) conducted a training study in which listeners were trained in the audio-visual modality with degraded speech syllables. Results showed that the performance increased only for the audio-visual conditions, and did not increase in the auditory-only or visual-only conditions. Interestingly, performance improved only for stimulus pairs that were "congruent" (i.e. the auditory and visual inputs were the same syllable) and did not increase for "discrepant" stimuli (i.e. the auditory and visual inputs were different syllables). It is possible that the feedback provided in DiStefano's study impacted their pattern of results. However, the question remains as to whether integration of discrepant stimuli can be trained. In the present study, five listeners received ten hours of training sessions in the audio-visual condition with degraded speech signals similar to those used by Shannon et al. (1995). The feedback given during training was designed to encourage McGurk-type combination and fusion responses, in contrast to DiStefano's study, in which feedback was given to encourage responses that matched the auditory signal. A comparison of pre-training and post-training scores showed little to no improvement in auditory-only performance, and a slight decrease in visual-only performance for congruent stimuli. Further, a substantial increase in McGurk-type responses was seen from pre- to post-test for discrepant stimuli. These results provide further support that integration is an independent process, and that the feedback provided strongly influences response patterns. This strong lack of generalization from training also should be incorporated into designing effective integration training programs for aural rehabilitation.

Book Synopsis Audiovisual Training Effects on L2 Speech Perception and Production by : Ying Li
Download or read book Audiovisual Training Effects on L2 Speech Perception and Production written by Ying Li and published by . This book was released on 2017-04-03 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on speech perception has found that visual cues play a significant role in the perception of speech sounds. Yet, it is still an unsettled question concerning whether audiovisual training could facilitate language learners' auditory perception and production of the target sounds. This book, therefore, presents a study that investigated whether audiovisual perception training could improve learners' auditory perception and production of L2 speech sounds.
Book Synopsis Training Effects in Audio-visual Integration of Sine Wave Speech by : Megan Exner
Download or read book Training Effects in Audio-visual Integration of Sine Wave Speech written by Megan Exner and published by . This book was released on 2008 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Speech perception is a bimodal process that involves both auditory and visual inputs. The auditory signal typically provides enough information for speech perception; however, when the auditory signal is compromised, such as when listening in a noisy environment or due to a hearing loss, people rely on visual cues to aid in understanding speech. Visual cues have been shown to significantly improve speech perception when the auditory signal is degraded in some way. The McGurk and MacDonald study (1976) strongly supported the fact that speech is not a purely auditory process and that there is a visual influence even with perfect auditory input. There is a growing interest in the benefit that listeners receive from audio-visual integration when the auditory signal is compromised. Remez et al, (1981) studied intelligibility when the speech waveform is reduced to three sine waves that represent the first three formants of the original signal. Remez discovered that sine wave speech is still highly intelligible even though a considerable amount of information was removed from the speech signal. Grant and Seitz (1998) looked at audio-visual integration performance of hearing impaired listeners by comparing a variety of audio-visual integration tasks using nonsense syllables and sentences. The study's results showed that even when the auditory signal is poor, speech perception is highly improved with the aid of visual cues. However, a large degree of variability was seen in the benefit that listeners receive from audio-visual integration. Further analysis suggested that at least some of this variability can be attributed to individual differences in listeners' abilities to integrate auditory and visual speech information. Studies in our lab have explored the differences in benefit that listeners receive from visual cues during audio-visual integration. We propose that one source of the variability in the benefit that listeners receive may be the overall amount of information available in the auditory signal. A previous study in our laboratory, Tamosiunas (2007) explored the audio-visual benefit that listeners received using highly-degraded sine wave speech. Results of this study indicated that listeners received little benefit from the addition of visual cues and in some cases these cues actually inhibited speech perception. A possible explanation for the difficulties in speech perception found in this study was the degree of exposure subjects had to sine wave speech. The present study explored whether the lack of audio-visual integration and benefit seen in Tamosiunas' (2007) study was a result of unfamiliarity with sine wave speech or whether this degree of auditory signal degrading inhibits audio-visual integration. To accomplish this, listeners in the present study were provided auditory and audio-visual training in sine wave speech perception. Results show that with training and exposure, speech perception performance did increase in both auditory and audio-visual conditions.
Book Synopsis Multisensory and sensorimotor interactions in speech perception by : Kaisa Tiippana
Download or read book Multisensory and sensorimotor interactions in speech perception written by Kaisa Tiippana and published by Frontiers Media SA. This book was released on 2015-06-26 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Speech is multisensory since it is perceived through several senses. Audition is the most important one as speech is mostly heard. The role of vision has long been acknowledged since many articulatory gestures can be seen on the talker's face. Sometimes speech can even be felt by touching the face. The best-known multisensory illusion is the McGurk effect, where incongruent visual articulation changes the auditory percept. The interest in the McGurk effect arises from a major general question in multisensory research: How is information from different senses combined? Despite decades of research, a conclusive explanation for the illusion remains elusive. This is a good demonstration of the challenges in the study of multisensory integration. Speech is special in many ways. It is the main means of human communication, and a manifestation of a unique language system. It is a signal with which all humans have a lot of experience. We are exposed to it from birth, and learn it through development in face-to-face contact with others. It is a signal that we can both perceive and produce. The role of the motor system in speech perception has been debated for a long time. Despite very active current research, it is still unclear to which extent, and in which role, the motor system is involved in speech perception. Recent evidence shows that brain areas involved in speech production are activated during listening to speech and watching a talker's articulatory gestures. Speaking involves coordination of articulatory movements and monitoring their auditory and somatosensory consequences. How do auditory, visual, somatosensory, and motor brain areas interact during speech perception? How do these sensorimotor interactions contribute to speech perception? It is surprising that despite a vast amount of research, the secrets of speech perception have not yet been solved. The multisensory and sensorimotor approaches provide new opportunities in solving them. Contributions to the research topic are encouraged for a wide spectrum of research on speech perception in multisensory and sensorimotor contexts, including novel experimental findings ranging from psychophysics to brain imaging, theories and models, reviews and opinions.
Book Synopsis Engineering Psychology and Human Performance by : Christopher D. Wickens
Download or read book Engineering Psychology and Human Performance written by Christopher D. Wickens and published by Taylor & Francis. This book was released on 2021-09-27 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forming connections between human performance and design, this new edition of Engineering Psychology and Human Performance examines human–machine interaction. The book is organized directly from a psychological perspective of human information processing, and chapters correspond to the flow of information as it is processed by a human being—from the senses, through the brain, to action—rather than from the perspective of system components or engineering design concepts. Upon completing this book, readers will be able to identify how human ability contributes to the design of technology; understand the connections within human information processing and human performance; challenge the way they think about technology’s influence on human performance; and show how theoretical advances have been, or might be, applied to improving human–machine interactions. This new edition includes the following key features: A new chapter on research methods Sections on interruption management and distracted driving as cogent examples of applications of engineering psychology theory to societal problems A greatly increased number of references to pandemics, technostress, and misinformation New applications Amplified emphasis on readability and commonsense examples Updated and new references throughout the text This book is ideal for psychology and engineering students, as well as practitioners in engineering psychology, human performance, and human factors. The text is also supplemented by online resources for students and instructors.

Book Synopsis Recent Research in Second Language Phonetics/phonology by : Michael Alan Watkins
Download or read book Recent Research in Second Language Phonetics/phonology written by Michael Alan Watkins and published by Cambridge Scholars Publishing. This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent Research in Second Language Phonetics/Phonology: Perception and Production reports the findings of seventeen interphonology studies on perception/production of sounds by different first language speakers. All the papers describe careful empirical research, and as such will be of great interest to anyone working, or intending to work, in the specific field of second language phonological acquisition. However, given that speech production and perception are highly complex skills, the research findings in this volume will also be relevant to those with a broader interest in language learning or cognition in general.

This book was released on 2007 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: (cont.) Results from our study added to existing evidence of the engagement of motor-articulatory strategies in visual speech perception. We also found that an individual's speechreading ability is related to the amount of activity in superior temporal cortical areas, including primary auditory cortex, pre-SMA, IFS and right AG during visual speech perception. Results from effective connectivity analyses suggest that posterior superior temporal sulcus may be a potential AV speech integration site; and that AG serves a critical role in visual speech perception when auditory information is absent for hearing subjects, and when auditory information is available for hearing impaired subjects. Also, strong excitatory projections from STS to inferior frontal gyrus (IFG) and premotor/motor areas, and a strong inhibitory projection from IFG to STS seem to play an important role in visual speech perception in all subject groups. Finally, correlation analyses revealed that in hearing aid users, the amount of acoustic and speech signal gained by using hearing aids were significantly correlated with activity in IFG.
