The text is written by the Argentinian author Juan Palazzo (1893-1921), which means that that there are some specialties in the vocabulary and the word order within the sentences. Maybe you will notice the influence of the Italian language. The text is read by an Argentinian lady. That also means that the text will be a bit different from the Castellan of Spain as well in the writing as in the pronunciation. The melody of the sentence differs, the sound of 'll' and 'y' sounds more like 'sh' and other differences. However, the text is conform with the official Argentinian norm and therefore, not at all 'wrong' as someone might feel.
