For example, the aspirated /p/ in “pin” and the unaspirated one in “spin” both fit in our same mental category of English /p/-although the same wouldn’t be true for every language! A child with phonological errors may have internalized the “wrong” rules-like disregarding the manner difference between /s/ and /t/ and storing them in the same mental category. When we learn the phonology of a language, our brains learn the rules for which qualities of sounds are phonemic and important for meaning (like the final voicing difference in /bæk/ vs /bæg/), and which aren’t. Phonological errors, on the other hand, are language-based, meaning that the child has incorrect or fuzzy mental representations of the speech sounds. We make a distinction between articulation and phonologically based errors because we need to address them differently and because the phonology side of things has had a tendency to get overlooked.Īrticulation errors are motor-based-there’s a breakdown in the movement of the articulators, so our therapy for articulation errors focuses on accurate placement and movement of the tongue, lips, teeth, etc. Let’s get this party started!Īrticulation versus phonology and why it matters Grab our downloadable chart of treatment approaches here, but don’t skip the discussion, ok? Context matters.

Your lingering questions, plus resources for digging deeperīefore you ask-yes, there’s a cheat sheet.A rundown of the major treatment approaches and their evidence bases.Is there even a difference? Paradigm shift! A quick review of the difference between articulation-based and phonologically-based SSDs.But never fear! You can search all of those topics using the filters in our database to find reviews on supporting speech for those kiddos. That means that we’re not talking motor speech (CAS & dysarthria), or speech disorders related to cleft/craniofacial conditions or to hearing differences. To narrow things down, we’ll be focusing only on idiopathic (traditionally called “functional”) SSDs-those rooted in articulation and/or phonology and without a known cause. That’s exactly why we’ve put together this Ask TISLP: to give you a starting point for making informed treatment decisions. All these evidence-based options can be a challenge to navigate, though, and choosing the right approach could mean the difference between a child meeting their goals and “graduating” from speech and that same child staying on the caseload for years. It’s one of the areas of practice our field was founded on, and one where we’re fortunate to have an array of treatment approaches (like, dozens) backed up by decades of research, for both phonological and articulation disorders. It’s one of those things our relatives who don’t really understand what we do assume is the only thing we do. We made a correction to the research linked under the complexity approach.

(1978) Articulation development in children aged three to nine years. San Diego, CA: Singular Publishing Group, Inc. Kent (Eds.), The new phonologies: Developments in clinical linguistics. A practical guide for families and teachers. The terms fricative, glide, stop, nasal, liquid and affricate refer to the way the sounds are made, or the "manner of articulation".īowen, C.
The term 'voiceless' is applied to sounds that are made without vocal cord vibration.
In column 3, the term 'voiced' refers to the vibration of the vocal cords while the sound is being made. These norms were established for a population of Australian children by Kilminster and Laird (1978). In Table 4 is an account of ages by which 75% of the children in a study pronounced individual consonants accurately. Created: Wednesday, 09 November 2011 08:51īowen, C.
