![]() An example of a “phonological process” is when an individual leaves off the last syllable of a word, no matter what sound is at the end of the word. Distortions (saying a sound kind of funky)Ī phonological disorder is when there are speech sound errors that are predictable and follow a pattern, known as a phonological process.Substitutions (saying one sound in place of another).In articulation disorders, speech sound errors are often consistent for certain sounds, like "s" or "t." Other examples of articulation disorders include leaving off a sound like saying “at” instead of “that,” or when a sound just doesn’t sound quite right, like it is distorted. “wabbit” instead of “rabbit” (Hey, Bugs Bunny!) beyond the typical age of acquisition. For this reason, speech-language pathologists (SLPs) sometimes use the term speech sound disorder to encompass both of these factors.Īrticulation Disorder vs Phonological DisorderĪn articulation disorder is when there are speech sound errors like saying the “w” sound instead of the “r” sound, e.g. There are cases when an individual has a purely articulation OR phonological disorder, but it is not always possible to clearly differentiate one or another. In this post, we will focus on functional speech sound disorders, which include articulation and phonology. A functional speech sound disorder means that there is no known cause for it. An organic speech sound disorder means that it is caused by a motor/neurological (e.g., dysarthria), sensory (e.g., hearing loss), or structural issue (e.g., cleft palate). Speech sounds disorders may be organic or functional in nature. Psychological Bulletin, 101, 192-212.What happens when the cute things your child says, like “ice keem” instead of “ice cream,” is no longer super cute, but rather make your child frustrated when others do not understand them? There are many reasons why they may be doing this - and one of these reasons is because they have a speech sound disorder, commonly known as an articulation and/or phonological disorder.Ī speech sound disorder is defined by ASHA as having difficulty producing speech sounds and segments. The nature of phonological processing and its causal role in the acquisition of reading skills. This ability to recall the speech sounds in one's language is also integral to phonological awareness. Phonological retrieval is the ability to recall the phonemes associated with specific graphemes, which can be assessed by rapid naming tasks (e.g., rapid Nonword repetition (e.g., repeat /pæg/) is one example ofĪ phonological working memory task. Information is then readily available for manipulation during phonological awareness tasks. Phonological working memory involves storing phoneme information in a temporary, short-term memory store (Wagner & Torgesen, 1987). Umbrella term phonemic awareness applies when the units being manipulated are phonemes, rather than words, onset-rime segments, or syllables. ![]() ![]() Range of tasks, such as speech sound segmentation and blending at the word, onset-rime, syllable, and phonemic levels. Phonological awareness is the awareness of the sound structure of a language and the ability to consciously analyze and manipulate this structure via a Therefore, it is important and necessary to monitor the spoken and written language development of children with phonological processing difficulties. Phonological processing is the use of the sounds of one's language (i.e., phonemes) to process spoken and written language (Wagner & Torgesen,ġ987).The broad category of phonological processing includes phonological awareness, phonological working memory, and phonological retrieval.Īll three components of phonological processing are important for speech production as well as the development of spoken and written language skills. ![]()
