A Timeline for Acquisition of Farsi Consonants: A First Language Acquisition Corpus-based Analysis

This study is one of the first endeavors in the realm of Farsi acquisition as the first language. The one-year utterances of five Iranian children were meticulously observed to determine the onset of steady perfect articulation of each consonant. The corpora were available from CHILDES which is the largest database for children’s corpus-based studies. Corpora analysis revealed that [w] and [ʒ] had been perfectly pronounced before the study initiated; [f] was accomplished before the 40th month; [m] and [x] were perfectly enunciated in the 42nd  month while the pronunciation [v] was idealized in the 44th  month along with [b], [d], [h] and [g]; [t], [n] and two approximants were perfectly produced in the 46th  month and [s] got its steady idealized pronunciation in the 48th  month;  [r] in addition to affricates and [z] and [ʃ] were in the process of completion when the inquiry terminated. 8 consonants from a total of 23 found their idealized articulations between the 43rd and 46th months of age.
