Nowadays, three kinds of theories still discuss the nature of speech units: auditory theories (Diehl, Lotto, and Holt 2004), motor theories (Galantucci, Fowler, and Turvey 2006) and perceptuo-motor theories (Schwartz et al. 2012). Briefly, supporters of the auditory (resp. motor, perceptuo-motor) theories claim that speech units are represented in the brain by auditory (resp. motor, perceptuo-m...

Background: Many elderly individuals complain of difficulty in understanding speech in noise despite having normal hearing thresholds. According to previous studies, auditory training leads to improvement in speech-in-noise perception, but these studies did not consider the etiology, so their results cannot be generalized. The present study aimed at investigating the effectiveness of envelope-b...

We studied the modification of auditory perception in three different conditions in twenty subjects. Observing other person's discordant articulatory gestures deteriorated identification of acoustic speech stimuli and modified the auditory percept, causing a strong McGurk effect. A similar effect was found when the subjects watched their own silent articulation in a mirror and acoustic stimuli ...

background and aim: auditory temporal resolution skill is calculated according to the minimum required time to analyze or integrate acoustic events. this skill, which is essential for speech perception, was evaluated by gap detection tests. the aim of this study was to determine the presence or absence of any differences between the right and left ear in the gap detection test. methods: after p...

For much of the past 50 years, the main theoretical debate in the scientific study of speech perception has focused on whether the processing of speech sounds relies on neural mechanisms that are specific to speech and language or whether general perceptual/cognitive processes can account for all of the relevant phenomena. Starting with the first presentations of the Motor Theory of Speech Perc...

The multimodal production and multisensory perception of speech have received much research attention in the past 60 years since Sumby and Pollack’s landmark demonstration that being able to see a talker’s face in noisy acoustic conditions dramatically improves speech intelligibility (Sumby and Pollack 1954). Myriad studies have pursued various conceptual lines about the production and processi...

Speech perception and speech production are two related complex processes. The success of cochlear implant can be evaluated only by studying both the perception and production. The present study compares the perception and production of the phonologically significant contrasts (vowels) of the children with cochlear implants with those of age matched normal hearing children. The vowel perception...

Perception results are presented that address the role of Lombard speech in auditory and audiovisual speech perception. Basically, visual enhancement neutralizes the advantage of Lombard speech observed for auditory perception. It remains an open question whether or not Lombard speech is preferable for perception studies of speech in noise.
