The speech samples suffer from common flaws in prosody. When it says "The Blue Lagoon is a 1980...", it omits the pause after Lagoon. When giving a definition, there should be a comma-length pause after the term. The pacing would be correct for a non-defining sentence later in the same article like "The Blue Lagoon is a popular subject for parodies, including ..." Fixing that requires higher than sentence-level learning, since it has to know that it's introducing a potentially unfamiliar term which can only be known from the sentence's context within the article.
