While phonotactics by itself appears to be a powerful cue, yielding a noticeable 4-5% improvement over the colloc3-nophon baseline, the learner seems to require at least around 500 utterances before the colloc3-phon model becomes clearly more accurate than the colloc3-nophon model.
even for only 100 utterances stress cues by themselves provide a 3% improvement to the colloc3-nophon model, indicating that they can be taken advantage of earlier.
