1 Module Recognition Algorithms
Seminar Speech Recognition Project Module Recognition Algorithms

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
