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.
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.
Traditionally, the minimal linguistic unit of phonetics is the phone—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones and it is also defined as the smallest unit that discerns meaning between sounds in any given language.

Phones are the segments of speech that possesses distinct physical or perceptual properties, regardless of whether the exact sound is critical to the meanings of words. . Whereas a phone is a concrete sound used across various spoken languages, a phoneme is more abstract and narrowly defined: any class of phones that the users of a particular language nevertheless perceive as a single basic ...
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 ...
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/ ).
Phonaesthetics (also spelled phonesthetics in North America) is the study of the beauty and pleasantness associated with the sounds of certain words or parts of words.The term was first used in this sense, perhaps by J. R. R. Tolkien, [1] during the mid-20th century and derives from Ancient Greek φωνή (phōnḗ) 'voice, sound' and αἰσθητική (aisthētikḗ) 'aesthetics'.
