From Juan Antonio Sandoval, Spanish writer: "The first thing one must make known, when emitting judgement of this beautiful Paraguayan singer, is the following: Her voice has been educated in the highest of school's. Her high-keyed notes are clear, well held, well placed, and of course are the result of long years of study. There is nothing of improvisation nor opportunism in Gloria. There is, on the contrary, a singer that SINGS”.
