Dyslalia

Dyslalia means difficulties in talking due to structural defects in speech organs, such as sigmatism (defective pronunciation of sibilant sounds, for example "S" pronounced as "TH") and rhotacism, in which the letter "R" pronounced as "I or Y". It does not include speech impairment due to neurological or other factors.
