title: A comparison of vocal parameters in adult bilingual Hebrew-English speakers.
abstract: OBJECTIVE
  There has been growing research on the effects of language on voice characteristics; however, few studies have examined the impact of language on vocal features within bilinguals. This study aimed to compare vocal parameters among bilingual Hebrew/English speaking individuals when speaking in Hebrew versus English.
  
  
  METHODS
  Forty bilingual participants (17 males and 23 females) between the ages of 23-60 years were asked to spontaneously speak about a neutral topic. Voice samples were digitalized into a tablet for perceptual and acoustic analyses of selected parameters.
  
  
  RESULTS
  Results show that there are changes in resonance, glottal attack, fundamental frequency variation and speech rate when adult bilingual speakers talk in Hebrew as compared to English.
  
  
  CONCLUSIONS
  These findings provide evidence that language plays a role in affecting vocal characteristics of bilingual individuals when they speak different languages.
