Perhaps you mean, "Me encanta cuando tú hablas español," otherwise, there only two discernible words in the query. Me encanta cuando tú hablas español means "It enchants me when you speak Spanish." However, "It enchants me" is not your typical English form, so a more pedestrian translation might be, "I really like it when you speak Spanish.""
"Cuado" is not a Spanish word. It is possible that it is a misspelling or a typo. Could you provide more context or try to clarify?

You left out an 'n'. It's 'de vez en cuando.' Literally, word for word, it means, "of time/instance/occasion/turn in when." It's interpreted as, "once in a while," or "occasionally."
