In English the /v/ in the phonetic spelling [edit, was: transcription] vee usually represents a voiced labiodental fricative (as /v/ in Italian Vincente) whereas most Spanish speakers will pronounce v (just like b) as voiced bilabial fricative or approximant. That is, I'd expect Vicente to be phonetically spelled bee-sen-teh (well aware that English /b/ is not a fricative as Spanish /v/ and /b/).
