Which remark summarizes research on issues away from speech development into the Off syndrome (DS) on purposes of telling health-related attributes and you can guiding coming lookup.
Report on the fresh new books are based on online searches having fun with MEDLINE, Google Scholar, PsycINFO, and HighWire Push, as well as thought of reference lists from inside the retrieved documents (including online supplies). Search terms emphasized features regarding voice, articulation, phonology, prosody, fluency, and you will intelligibility.
The next findings pertain to five big regions of feedback: voice, speech sounds, fluency and you may prosody, and you may intelligibility. The initial big city is sound. No matter if a good amount of research has claimed to your singing abnormalities for the DS, big concerns will still be towards character and regularity of one’s phonatory diseases. Consequence of perceptual and you may acoustic research has started combined, so it is hard to mark enterprise results or perhaps to select sensitive and painful tips to own upcoming investigation. Another biggest urban area is actually message tunes. Articulatory and you may phonological studies show that message designs inside DS try a variety of put off invention and you may problems perhaps not seen in normal innovation. Defer (we.age., developmental) and you may disordered (i.elizabeth., nondevelopmental) designs are obvious of the age from the 3 years, although DS-associated irregularities perhaps come earlier, even yet in kids babbling. The third big urban area is actually fluency and prosody. Stuttering and/otherwise cluttering occur in DS at prices from ten%–45%, in contrast to regarding 1% regarding general people. Lookup in addition to things to extreme interruptions into the prosody. The brand new 4th significant urban area is intelligibility. Education continuously reveal marked restrictions in this region, but only has just gets the research moved past simple get bills.
