* Before a vowel: The "B" is pronounced as a voiced bilabial stop, similar to the English "b" sound. Examples: bien (good), beau (beautiful).
* Before a consonant: The "B" is silent. Examples: bonjour (good morning), bain (bath).
However, there are some exceptions:
* When "B" is followed by "R", it is pronounced as a voiced uvular fricative, similar to the French "R" sound. Examples: braser (to braze), broche (skewer).
* In some words of foreign origin, the "B" might be pronounced as in English. Examples: box, baby.
It's important to remember that French pronunciation is often more nuanced than English, and the precise sound of "B" can vary slightly depending on the context.
