The word "biaser" is spelled with a "s" in the middle, not a "c" as some may assume. The correct pronunciation is [ˈbaɪəsər], with stress on the first syllable. The "s" sound is represented by the letter "s" and not "c" because it follows the vowel "i", creating a soft "s" sound. This is a common spelling pattern in English, seen in words such as "excise" and "rejoice." It's important to pay attention to such spelling patterns to avoid common mistakes while writing.
