Big or Vig? Greek's B Sound Hides Behind Two Letters

In Greek, a true B sound is usually written with two letters together (μπ), while the single letter beta actually represents a V-like sound. That means your ear and mouth may be more used to associating a single letter with V than with B, which can cause English B's to soften toward V — turning 'big' into something closer to 'vig,' or 'boat' into 'voat.' English needs a firm, complete lip closure for B, with no air escaping through a gap, unlike the more open V sound. Try 'big,' 'boat,' and 'cab,' really pressing your lips fully together before releasing the B, feeling zero air leak through. Two-minute drill: alternate 'big' and 'vig' (even though the second isn't a real word), noticing the full lip closure for B versus the lip-and-teeth contact for V. Once your lips remember that firm closure, your B's will stay clearly B's in English.
