Lallation (other)
Lallation may refer to: * A developmental stage in infantile speech from around 7–8 months when a child repeats (often incorrectly) sounds they have heard * A difficulty with enunciation which makes ''l'' sound like ''r'' (see lambdacism) or vice versa (see rhotacism Rhotacism () or rhotacization is a sound change that converts one consonant (usually a voiced alveolar consonant: , , , or ) to a rhotic consonant in a certain environment. The most common may be of to . When a dialect or member of a language fa ...

Phonological Development
Phonological development refers to how children learn to organize sounds into meaning or language (phonology) during their stages of growth. Sound is at the beginning of language learning. Children have to learn to distinguish different sounds and to segment the speech stream they are exposed to into units – eventually meaningful units – in order to acquire words and sentences. 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.” Once "cup" is able to be extracted from the speech stream, the child has to assign a meaning to this word. Furthermore, the child has to be able to distinguish the sequence “cup” from “cub” in order to learn that these are two distinct words with different meanings. Finally, the child has to learn to pr ...

Lambdacism
A speech sound disorder (SSD) is a speech disorder in which some sounds (phonemes) are not produced or used correctly. The term "protracted phonological development" is sometimes preferred when describing children's speech, to emphasize the continuing development while acknowledging the delay. Classification Speech sound disorders may be subdivided into two primary types, articulation disorders (also called phonetic disorders) and phonemic disorders (also called phonological disorders). However, some may have a mixed disorder in which both articulation and phonological problems exist. Though speech sound disorders are associated with childhood, some ''residual'' errors may persist into adulthood. Articulation disorders Articulation disorders (also called phonetic disorders, or simply "artic disorders" for short) are based on difficulty learning to physically produce the intended phonemes. Articulation disorders have to do with the main articulators which are the lips, teeth, ...
