No one mentioned that those verbs do not match the same aspect. Antonio listed "приводить" which is imperfective (process or iterative) and "принести", "привезти" which are perfective (single completed action as a whole).

I'd like to clarify that:

приводить (imperf.) - привести (perf.) (a person or an animal by walking together)
приносить (imperf.) - принести (perf.) (in your hands, by walking)
привозить (imperf.) - привезти (perf.) (by vehicle)

Note that the infinitive forms of "привести" and "привезти" are pronounced the same way (due to devoicing of "з" before the voiceless "т"): actually we pronounce both of them as [привистИ]. However, the conjugation forms are different:
привести привезти
Future, Я приведу привезу
Future, Ты приведёшь привезёшь
Future, Он/Она приведёт привезёт
Future, Мы приведём привезём
Future, Вы приведёте привезёте
Future, Они приведут привезут
Past, Masc. привёл привёз
Past, Fem. привела привезла
Past, Plural привели привезли
Imperative приведи привези

(Note: the stress is on the LAST syllable in all the conjugation forms of the both verbs).

And to show the difference between the verbs:

Я привёл Анну на твой день рождения. (I came to your birthday party with Anna, we walked together, and I insisted that she should accompany me)
Я привёз Анну на твой день рождения. (The only difference is we came by car, or another vehicle)
Я принёс Анну на твой день рождения. (I came to your birthday party carrying Anna on my arms, she did not walk herself).

So, you can actually use "приносить/принести" with animate objects as well. But it would mean you carry someone or something on your arms or in your hands.
