Can your intelligence effect your speech and articulation? I found this interesting post on Reddit earlier about this topic. I really feel this post as someone with speech disorders and a intellectual disability I’ve wondered this before. Is it true tho?
Correlation vs. causation.
A lot of things which impact “intelligence” can also have varying impacts on speech/articulation/communication skills. However it is important to note that the correlation isn’t strongly positive or negative (IE savant syndrome).
So while some disorders may have some common correlations with specific speech/articulation patterns they (usually) are not good diagnostic criteria and extremely broad generalizations like the one above are particularly bad.
