I got lost trying to decode your logic for two consonants, three 
consonants etc, so here is a simple implementation of the rules from 
Wikipedia instead.

def translate(words)
  words.gsub(/\w+/) do |word|
    case word
    # In words that begin with consonant sounds, the initial consonant 
or
    # consonant cluster is moved to the end of the word, and "ay" is 
added.
    # Note that "qu" is treated as a consonant sound.
    when /^((b|c|d|f|g|h|j|k|l|m|n|p|qu|r|s|t|v|w|x|y|z)+)(.*)/i
      "#{$3}#{$1}ay"
    # In words that begin with vowel sounds or silent consonants, the 
initial
    # vowel is removed and the syllable "way" added to the end of the 
word
    # FIXME: silent consonants are not considered here.
    when /^[aeiou]+(.*)/i
      "#{$1}way"
    else
      word
    end
  end
end

puts translate("pig computer happy question another about quale square")

You may find the above rather terse for your liking, but it boils down 
to "if the word matches this pattern, then rebuild it using the captured 
parts like this". It's an example of the power and brevity of ruby :-)
