Now I feel guilty for saying this brucha in such a half hearted manner for so many years. Thanks for the information about the importance of the Bracha and the correct way to pronounce it.
@Ginno Ricci harav pronounced "vav" properly, that is to say - "wow" (like in arabic). Perhaps you can ask old sepharadim/mizrahim (but most certainly - temanim) how do they pronounce their vavs. The consonantal "v" sound should only be created by soft bet.
