Instance Method Details

#next(stack, maxlength, &block) ⇒ Object

Generates a phoneme of at most the given length that should follow this vowel.

If the last two characters in the stack (including this one) were vowels, then this will always generate a consonant. Otherwise, 40% of the time it will generate a single-character vowel and 60% of the time it will generate a consonant.

It is never possible for two consecutive vowel phonemes to result in more than 2 vowel characters in the stack.
