Young and old, there are those of you who have been born that way. And if that has not been the case, the speech impediment that you or someone close to you, has developed over time and sometimes even suddenly overnight could have been caused by some or another physical and/or emotional or mental trauma, which, incidentally, can be overcome. That is to say this: Physical trauma experienced can be overcome.
It is just a matter of time, and this usually requires patience. It could, however, be influenced by how well (or not) a patient responds to therapy that addresses the emotional or mental trauma experienced from a sudden accident or illness. And obviously not overnight, but speech therapists orlando relevant to the incident or physical and mental condition diagnosed can help you or others overcome the speech impediment.
And the speech deficiency may also have nothing to do with hereditary factors. It could have nothing to do with the fact that a person is born with a hearing deficit perhaps.

The recently migrated worker may still have some way to go in terms of proper acculturation.
That he understands the local language, lingo and dialect well enough will be exemplary and it does happen often enough.

It is the influence of his home language or mother tongue, a heavy accent, that may be impeding his ability to communicate properly in the local tongue. And this kind of speech impediment, this too, can also be overcome.
