What are the stages of speech perception?

Current accounts of speech perception emphasize process and divide the process into a hierarchy of stages: auditory, phonetic, phonological, and so on (see for example, Fry, 1956; Chistovich et al., 1968; Studdert-Kennedy, in press).

What is the model of speech perception?

Speech perception models were designed to help detect and interpret speech for a great number of reasons, namely to help understand what utterances are being produced when it is difficult to distinguish them.

What is the main point behind the motor theory of speech perception?

The Motor Theory of Speech Perception is a proposed explanation of the fundamental relationship between the way speech is produced and the way it is perceived. Associated primarily with the work of Liberman and colleagues, it posited the active participation of the motor system in the perception of speech.

What was the McGurk effect?

First, the McGurk effect should be defined as a categorical change in auditory perception induced by incongruent visual speech, resulting in a single percept of hearing something other than what the voice is saying.

What are the factors that influence speech perception?

Conclusion: Three factors were identified that affected speech perception improvement postimplantation: speech intelligibility, preimplantation hearing levels, and communication mode.

How is speech perception developed?

Experiments have revealed conclusively that our perception and understanding are influenced by a speaker’s face and accompanying gestures, as well as the actual sound of the speech (Massaro 1998). Consider a simple syllable identification task.

Can motor theory of speech perception explain the McGurk effect?

The answer to the question is yes. For example, seeing a speaker produce one syllable while listening to a different syllable can affect how the heard syllable is perceived (the McGurk effect; e.g., Massaro, 1987; McGurk & MacDonald, 1976).

Which theory of speech perception proposes that speech perception is an innate human unique capacity?

The motor theory of speech perception is the hypothesis that people perceive spoken words by identifying the vocal tract gestures with which they are pronounced rather than by identifying the sound patterns that speech generates.

What does the McGurk illusion demonstrate about speech perception?

The McGurk effect is a perceptual phenomenon that demonstrates an interaction between hearing and vision in speech perception. The illusion occurs when the auditory component of one sound is paired with the visual component of another sound, leading to the perception of a third sound.

What is the rubber hand illusion?

The Rubber Hand Illusion (RHI) is a tantalizing illusion, where the feeling that a rubber hand belongs to one’s body (feeling of ownership) is brought about by stroking a visible rubber hand synchronously to the participant’s own occluded hand.

What part of the brain processes speech perception?

Within sec- ondary auditory cortex, on the superior temporal gyrus, lies Wernicke’s area, a region traditionally associated with the perception of speech (see Figure 4). More recent studies have also demonstrated activation in frontal regions of the brain (e.g. Broca’s area) during speech and auditory perception tasks.

What is Coarticulation in phonetics?

Coarticulation refers to changes in speech articulation (acoustic or visual) of the current speech segment (phoneme or viseme) due to neighboring speech. In the visual domain, this phenomenon arises because the visual articulator movements are affected by the neighboring visemes.
