The aim of this research was to study language functions of the right hemisphere of the brain in the left hemisphere–damaged patients and compare them with healthy people. In this research, which is kind of Descriptive-Analytical, upon random sampling, two groups of the left hemisphere–damaged patients (20 men &10 women) were selected among people referred to Imam Reza Neuro Clinic, as well as 30 healthy people. Then tests of Right Hemisphere Language Collection (Brian, 1995) and test of Application Acts &Competency of Language (Mehri, 1381) were used, to compare patients' language functions with those of healthy people. The results of the research were analyzed. Analysis of data includes two parts: Descriptive Statistics and Inferential Statistics. The results of the research show that there are no significant differences between healthy and damaged people in view of sex, but there are significant differences between healthy and damaged people in 1-Metaphire test, 2-Written Metaphor test, 3-Comprehension of inferred meaning, 4-Appreciation of humor, 5-Lexical-semantic test, 6-Methapor production test, 7-Written proverb test, 8-Proverb production test, 9-Indirect speech acts test. These results indicate that abilities are not specific to the right hemisphere because people whose left hemisphere is damaged suffer from these disorders, too.

Two anterior aphasic patients (one man and one woman) were recorded for their productions of six Persian vowels and were compared to a group of four normal speakers (two men and two women). Praat was used to obtain the spectrograms of the sound files. Vowel duration values showed that normal women produced longer vowels compared to normal men. The male patient produced all vowels shorter, and the female patient produced all vowels longer than all four normal subjects. Although there were no significant differences in the formant frequency values of the four non-round vowels across groups, the two round vowels /o, u/ showed a pattern different from that of other vowels in aphasic speech
