The factor is calculated by how attractive a woman is before her voice is heard (eg. a 6, she's not extremely attractive, but is noticed) after her foreign accent is heard her rating on the "attractiveness scale" can fluctuate up to a value of 3 depending on your preference for specific accents. (The 6 that was previously spoken of has increased to a value of 8.5 or even 9 if her accent is French or Australian. If her accent is Indian however, the foreign factor can dercrease her attractiveness as low as a 3.)
