It goes on to say that "Children need to be phonemically aware (especially able to segment and blend phonemes)". [100] The skills of segmenting and blending phonemes are a central aspect of synthetic phonics. In grades two and three children receive explicit instruction in advanced phonic-analysis and reading multi-syllabic and more complex words.
The PAL introduces identification, segmentation, blending, and manipulation of speech sounds in syllables. It does not encourage reading using the whole-word approach but instead teaches children to break written words up into individual graphemes and matching letters with their corresponding phonemes before reassembling the phonemes back into words to read.
Phonological awareness involves the detection and manipulation of sounds at three levels of sound structure: (1) syllables, (2) onsets and rimes, and (3) phonemes. Awareness of these sounds is demonstrated through a variety of tasks (see below).
Phoneme isolation: which requires recognizing the individual sounds in words, for example, "Tell me the first sound you hear in the word paste" (/p/). Phoneme identity: which requires recognizing the common sound in different words, for example, "Tell me the sound that is the same in bike, boy and bell" (/b/).
Phonemic awareness and the resulting knowledge of spoken language is the most important determinant of a child's early reading success. [21] Phonemic awareness is sometimes taught separately from phonics and at other times it is the result of phonics instruction (i.e. segmenting or blending phonemes with letters).
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.
One reason that speech segmentation is challenging is that unlike between printed words, no spaces occur between spoken words. Thus if an infant hears the sound sequence “thisisacup,” they have to learn to segment this stream into the distinct units “this”, “is”, “a”, and “cup.”
Laryngeal features: The features that specify the glottal states of sounds. [+/− voice] [7] This feature indicates whether vibration of the vocal folds occurs with the articulation of the segment. [+/− spread glottis] [7] Used to indicate the aspiration of a segment, this feature denotes the openness of the glottis. For [+sg], the vocal ...
