"Who are you?" in Spanish is "¿Quién eres?" One of the best sites for translating English to Spanish is Google Translate. You type in the English word(s) in the box (it will say out loud what you wrote) and then it will translate in Spanish and say it out loud. You can change the languages at anytime. --The Dog Expert
