The document discusses how vowels are sometimes dropped in pronunciation, resulting in a reduction of syllables. It provides examples of words that typically have more syllables when fully pronounced, but in casual speech may lose interior vowels and have fewer syllables, such as "dramatic" becoming "drama-tic" or "laboratory" becoming "labra-tory". In total, over 20 word examples are given that demonstrate this phenomenon of "dropped lines" or reduced syllables in pronunciation.

Review: the number of vowels Reduction of syllables
 Today /   2 syllables
 Hotel /   2 syllables
 Vanity /   3 syllables
But sometimes vowels sounds disappear giving as a consequence a
reduction in the number of syllables.
