In this example, the SpeakableSpecification is used to indicate which parts of the webpage can be read aloud by a text-to-speech device. The xpath property is an array of XPath expressions that target specific elements on the page that should be included in the spoken content. In this case, the SpeakableSpecification includes the page title, meta description, the first heading (h1), and the first two paragraphs (p) of the page content.
