Just curious to know whether people having a lisp (speech defect) write in the same way as they pronounce the word. For example they pronounce s as /θ/ and z as /θ/. So, do they write 's' as 'th' like with the word thick written as sick?
Another example as Spanish is spoken with a lisp, like pez is pronounced /peθ/. Is writing the same?
I hope this question doesn't hurt any emotions, but I'm doing a research, so need an answer for it.
