RE: [phono-tx] Initial Consonant Deletion

Suzanne and Janet,

Suzanne,

RE: " I, too, had heard that ICD is a red flag/dire predictor. I guess one could speculate that if it isn't resolved early it can become habitual. Having
only dealt with a handful of children with this difficulty (I'm thinking ?5), and it doesn't appear that often from what I understand, one would then have to question what the basis of the prediction is?"

Most of the phonological patterns that are seen in children with speech sound disorders ARE FOUND in typical development. They become problematic when they persist beyond typical ages of elimination.

Some of the phonological processes (or phonological patterns) that are seen in children with speech sound disorders ARE NOT FOUND in typical development. These include BACKING: tea = key, did = gig, pin=ping, she = key, measure = mega, zoo = goo; INITIAL CONSONANT DELETION: top = op; DEVOICING OF STOPS goat = coat; SYSTEMATIC SOUND PREFERENCE SUBSTITUTIONS (e.g., /s/ as a "favourite articulation"; /d/ as a "favourite articulation"); GLOTTAL REPLACEMENT; and FINAL VOWEL ADDITION (but = butta).

Initial Consonant Deletion (ICD) IS FOUND in the typical development of Finnish, French and possibly Hebrew. Moreover, as discussed here previously, ICD has been attested in the Spanish in three year olds. But it is not characteristic of English phonological acquisition. That is why it has been called a "red flag". I don't think I have ever heard of it being referred to before as a "dire predictor". "Dire" has connotations of having dreadful or terrible or calamitous consequences, and I don't think THAT can be claimed for ICD! It is just not that disastrous. However, it should make us sit up and take notice because it is non-developmental, often associated with severe SSD, very destructive of intelligibility if it is pervasive, and sometimes difficult to work on if it occurs with one or more other syllable structure processes.

Any non-developmental processes require timely investigation by SLPs, and in my view this is particularly the case for Backing and Initial Consonant Deletion.

Janet,

It would be interesting to know your two year old's phonetic repertoire and which phones he uses syllable initially and which he uses syllable finally. I saw a child with the ICD tag recently for an opinion, and when he turned up I found he had no fricatives in his repertoire, and no substitution processes! So when a fricative was needed he did not substitute another sound - hot as ot, sea was ee, shoe was oo, and find was ind, etc. He did brilliantly with inventory expansion using the Miccio stimulability program and "Word Flips".

RE: " Initially, he had difficulty matching vowels"

What does "matching vowels" mean here?

Best wishes,
Caroline
