Phonemic awareness is a part of phonological awareness in which listeners are able to hear, identify and manipulate phonemes, the smallest mental units of sound that help to differentiate units of meaning . Separating the spoken word "cat" into three distinct phonemes, /k/, /æ/, and /t/, requires phonemic
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.
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.
While exposure to different sound patterns in songs and rhymes is a start towards developing phonological awareness, exposure in itself is not enough, because the traditional actions that go along with songs and nursery rhymes typically focus on helping students to understand the meanings of words, not attend to the sounds.
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.
It consists of many different language and grammatical functions, such as: features, segments (phonemes), syllabic structure (unit of pronunciation), phonological word forms (how sounds are grouped together), grammatical features, morphemic (prefixes and suffixes), and semantic information (the meaning of the words).
Regular words are those in which there is a regular, one-to-one correspondence between grapheme and phoneme in spelling. Irregular words are those in which no such correspondence exists. Nonwords are those that exhibit the expected orthography of regular words but do not carry meaning, such as nonce words and onomatopoeia. [207]
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.
