Stuttering behavior in Kurdish-Persian bilingual speakers

The present study was conducted to investigate the dissociation between some linguistic variables including the Mean Length of Utterance (MLU) and Type Token Ratio (TTR) and stuttering severity in both languages of Kurdish-Persian bilingual people who stutter (PWS). The connected speech of 31 PWS (age ranges: 9 to 13 years old) speaking in their first (Kurdish) and second (Persian) languages were collected. The results indicate that there is a significant correlation between stuttering severities in both languages. Moreover, it seems that MLU in Kurdish could predict the stuttering occurrence in the Persian language.
