syllables: count syllables in a text

For any word not in the dictionary, the syllable count is estimated by counting vowel clusters. englishSyllables is a quanteda-supplied data object consisting of a named numeric vector of syllable counts for the words used as names. This is the default object used to count English syllables. This object that can be accessed directly, but we strongly encourage you to access it only through the syllables() wrapper function.
