Speech Disability inside Off Syndrome: An assessment

This feedback summarizes search towards conditions away from message development into the Off disorder (DS) to the purposes of telling scientific qualities and you can at the rear of upcoming search.

Approach

Writeup on the fresh new literature are considering online searches having fun with MEDLINE, Bing Student, PsycINFO, and you can HighWire Press, and additionally planning from resource directories inside the retrieved files (and additionally on the web sources). Search terms emphasized services related to sound, articulation, phonology, prosody, fluency, and you may intelligibility.

Findings

The next findings have to do with five significant regions of opinion: sound, message songs, fluency and you will prosody, and you can intelligibility. The original significant town try voice.

Education constantly inform you marked constraints in this field, but simply recently contains the lookup moved past easy score bills.
