Table 1 Acoustic filtering performed by a simple Viterbi alignment on context-free HMMs (Baseline), with GMM-filtering and ASAP pruning (A-GMM), with ASAP and smart querying coupled with GMM-based filters (A-SR-GMM) and MLP-based filters (A-SR-MLP). Performances are reported in terms of recall, filtering rates and CPU time consumption. Tests are conducted on the EPAC spontaneous speech corpus.
