The effect occurs when missing phonemes in an auditory signal are replaced with a noise that would have the physical properties to mask those phonemes, creating an ambiguity. In such ambiguity, the brain tends towards filling in absent phonemes. The effect can be so strong that some listeners may not even notice that there are phonemes missing.
There are three types of connectivity: (1) feedforward excitatory connections from input to features, features to phonemes, and phonemes to words; (2) lateral (i.e., within layer) inhibitory connections at the feature, phoneme and word layers; and (3) top-down feedback excitatory connections from words to phonemes.
A phoneme is a sound or a group of different sounds perceived to have the same function by speakers of the language or dialect in question. An example is the English phoneme /k/, which occurs in words such as cat, kit, scat, skit.
Figure 4: Example identification (red) and discrimination (blue) functions. Categorical perception is involved in processes of perceptual differentiation. People perceive speech sounds categorically, that is to say, they are more likely to notice the differences between categories (phonemes) than within categories.
Consistent with the role of the ADS in discriminating phonemes, [120] studies have ascribed the integration of phonemes and their corresponding lip movements (i.e., visemes) to the pSTS of the ADS. For example, an fMRI study [ 150 ] has correlated activation in the pSTS with the McGurk illusion (in which hearing the syllable "ba" while seeing ...
Speech segmentation is the process of identifying the boundaries between words, syllables, or phonemes in spoken natural languages.The term applies both to the mental processes used by humans, and to artificial processes of natural language processing.
Available published tests of phonological awareness (for example PhAB2 [7]) are often used by teachers, psychologists and speech therapists to help understand difficulties in this aspect of language and literacy. Although the tasks vary, they share the basic requirement that some operation (e.g., identifying, comparing, separating, combining ...
Biederman suggests that in the same way speech is made up by phonemes, objects are made up by geons, and as there are a great variance of phonemes, there is also a great variance of geons. It is more easily understood how 36 geons can compose the sum of all objects, when the sum of all language and human speech is made up of only 55 phonemes.
