How do we explain these errors: not just producing one phoneme after another. Words are the same way: ordered hierarchically into many levels. Syllables are organized hierarchically: onsets, rhymes, codas. Assembling a word involves assigning phonemes to the hierarchy. As we produce speech we move from one level of organization to the next. Each step involves assembling units into a sequence.
