Language acquisition is carried out by comprehending the stimulants and attaching them in the production process. It is often discussed that whether there is a relationship between language acquisition and the mental capability. According toThurston’s multiple factors theory (1938) there are seven basic structures constitutes the ‘Main Capabilities’ of intelligence. One of the seven factors mentioned is the “word fluency”. Word fluency factor is one of the verbal (i.e.,expressive language, speech) factors. The important ability is to be able to produceas many words as possible quickly. There are tests developed to be able to measurethis ability, in English speaking countries for instance, words starts with the sounds/K,A,S/ or /F,A,S/ are chosen for this task. However, the adequacy of these soundsinto Turkish has not been studied.The purpose of this study is to define if there is a corelation of the sounds beginswith /a/, /s/, /t/, /k/, /m/ in 8000-1000 frequency, /ç/, /y/, /e/, /p/, /i/ in 4000 frequencyand /f/, /n/, /l/, /o/, /r/ in 2000 frequency and the children’s verbal outputs thatbegins with those sounds. All the word frequencies are determined by a researchcarried out by the Turkish Language Society (TDK). The study included the results of 150 children including both children with normal speech and children with speech-language problems ages between 4-12years old. The participants were given a word fluency test which was preparedaccording to the TDK’s written frequency list with the occurrance of frequencyrange between 8000-1000.There were 12 sounds in the word fluency test (a, s, t, k, m, ç, y, e, p, i, f, n, l, o, r),a 10 second was given between sounds to be produced, and each child is given aminute to produce the words starting with the target sound. The city and peoplenames were not accepted as part of target words. Results were discussed in detailsaccording to the sounds and the subjects in the study
