Código de barras

Bar codes, each accompanied by fragments of sentences and a play button are arranged on opposite sides of the page. Pressing the play button of the bar codes on the right hand side the user hears the words read aloud in a warm, present voice. The bar codes on the left side of the page also have voice recordings, but this voice sounds tinny and distant and speaks single English words, such as "distance", instead of the longer Spanish phrases that are written beneath each bar code.
