In another of my pronunciation clarification posts, let me explain the difference between ‘glove’ and ‘globe’.
Put the glove/globe over there.
This is about the difference between /v/ and /b/.
/b/ is a pair sound with /p/ and your lips touch.
/v/ is a pair sound with /f/ and your lips don’t touch. Your top teeth can lightly rest on your bottom lip.
Both /b/ and /v/ are voiced sounds where you use your voice to make the sounds. (You don’t use your voice to make /p/ and/f/.)
