Figure 7From: Integrated exemplar-based template matching and statistical modeling for continuous speech recognitionLattice rescoring phone accuracy (percent) using different numbers of GMM indices for frame representation. Using multiple GMMs such as 3, 5, and 7 to label each frame can get better performance than using one single GMM. For both LLR and KL distances, the accuracy performance peaked when five GMMs were used for frame labeling.Back to article page
