Hola Robert,
We understand that for Spanish learners in Latin America there are a few aspects of the language that are different. We plan on offering lessons also based on Latin American Spanish but at the moment Kwiziq is focused on Peninsular Spanish, as is described in our FAQ section: What kind of Spanish will I learn?
Nevertheless we will offer some exercises soon where different pronunciation is used, e.g. from Southern Spain, which is very similar to that of many Latin American countries, in order to show a variety of accents.
Saludos cordiales,
Inma
