Figure 11

Significance levels of word error rate difference between the phoneme-level bagging and boosting and HMM. The histograms are created from 10,000 bootstrap samples of the test data, as described in Section 4.2. WERdiff displays the average difference in word error rate performance between the two methods. Positive values indicate that the first method has lower error than the second. The percentage values indicate the tail mass of the histogram to that point.Bag versus HMMBoost versus HMM
