2. Static Structure

3. Static Structure
Based on a adjacency-list structure

4. Dynamic Structure
Viterbi algorithm:
Beam search
Window search

5. Improvements Improving the static structure
VNSA (variable N-gram Stochastic Automaton)
Static tree based representation (by Federico in ’95)
Improving the dynamic structure ?

6. Interfaces recog.cpp contains the main routine
Input to the search algorithm:
Static structure: a SpectralHmm object (not declared const !)
Reference to the database, a DbaseVoc object (not declared const !)
Configuration settings
Output of the search algorithm:
A HypoList object with references to the recognized phonemes/words
