In this paper three theories of speech monitoring are evaluated. The perception-based approach proposes that the same mechanism employed in understanding other-produced language, the speech comprehension system, is also used to monitor one's own speech production. A conceptual, an inner, and an auditory loop convey information to a central, conscious monitor which scrutinizes the adequacy of th...

An articulatory speech synthesizer comprising a three-dimensional vocal tract model and a gesture-based concept for control of articulatory movements is introduced and discussed in this paper. A modular learning concept based on speech perception is outlined for the creation of gestural control rules. The learning concept includes on sensory feedback information for articulatory states produced...

background :older adults with cerebrovascular accident (cva) show evidence of auditory and speech perception problems. in present study, it was examined whether these problems are due to impairments of concurrent auditory segregation procedure which is the basic level of auditory scene analysis and auditory organization in auditory scenes with competing sounds. methods : concurrent auditory seg...

introduction: auditory temporal resolution and auditory temporal ordering are two major components of the auditory temporal processing abilities that contribute to speech perception and language development. auditory temporal resolution and auditory temporal ordering can be evaluated by gap-in-noise (gin) and pitch-pattern-sequence (pps) tests, respectively. in this survey, the effect of biling...

Studies of the McGurk effect demonstrate that observers integrate auditory information with visual information from a talker’s face during speech perception. The findings from these studies pose challenges for theories of speech perception that must account for how and why the auditory and visual information are integrated. One theoretical issue concerns the objects of speech perception. Some r...

In face-to-face conversation speech is perceived by ear and eye. We studied the prerequisites of audio-visual speech perception by using perceptually ambiguous sine wave replicas of natural speech as auditory stimuli. When the subjects were not aware that the auditory stimuli were speech, they showed only negligible integration of auditory and visual stimuli. When the same subjects learned to p...

Adult speakers have developed precise forward models of articulation for their native language and seem to rely less on auditory sensory feedback. However, for learning of the production of new speech sounds, auditory perception provides a corrective signal for motor control. We assessed adult German speakers' speech motor learning capacity in the absence of auditory feedback but with clear som...

We consider the problem of speech recognition given visual and auditory information, and discuss some of the ways that speech synthesis can provide assistance. Three possible contributions of synthetic visual speech are discussed: First, the use of synthetic speech to study human speech perception, second, the use of speech synthesis techniques to instantiate models of human speech production, ...
