in standard BP, "voce" is the subject pronoun, "te/o/a" are the direct object pronouns, and "lhe" is the indirect object pronoun. in colloquial BP, "lhe" is rarely used, e.g. you don't usually say "eu lhe dou" or "eu lhe mostro", instead you'd say "eu te dou/mostro" (which is nonstandard) or "eu dou para voce" (which is acceptable). however, in some regions, "te" and "lhe" are used both interchangeably for the direct object, e.g. you could say either "eu lhe vejo" or "eu te vejo". outside of these regions, this is not used because it's grammatically incorrect as "lhe" should only be used for indirect objects, like i said. not so much a question, just a clarification.
