This effect disappears starting from around 1000 utterances; for inputs of size 1000 and larger, the net-gain of stress drops from roughly 10% to a 3-4% improvement.
while we did not notice any relationship between input size and impact of stress cues for the colloc3-nophon model, we do see such an interaction for the combination of phonotactics and stress cues which, taken together, lead to a larger relative gain in performance on smaller inputs than on large ones.
