Robust, N-Best Formant Tracking

We describe a robust, N-best formant tracker. The 2 stage algorithm initially finds single formants or parts thereof. In the second stage a robust dynamic programming search with a wild card mechanism is employed to find the N best consistent interpretation of the initial formant information. The selection of the correct formant tracks is delayed until after the phonetic search, thus overcoming the lack of robustness of traditional formant trackers by delaying the final decision until after phonemic classification.
