Purpose:
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.
Conclusion:
These findings provide evidence that language plays a role in affecting vocal characteristics of bilingual individuals when they speak different languages.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
