"Vuol" and "vuole" is the same. It's an euphonic form more or less like the "I am" and "I'm" in English. In the verb "volere" the sound of the intervocalic "L" can be often combined with any following consonant or vowel in order to give more musicality to the sentence. Example: "Vuole andare fuori" (he wants to go outside). "Vuol andare fuori" is more harmonious as sounds, but the meaning is the same. "Vuole dire che e' importante". (he/she wants to say it's important) "Vuol dire che e' importante".
