Isolated word recognition and visualization software "Recognition" has been developed. Isolated word recognition is based on dynamic time warping. Three types of local continuity constraints are available: III,V and VIII- Itakura. Relaxed endpoint constraints also are possible. Energy based algorithm is used for endpoint detection. LPC features are used for pattern comparison. Symmetric likelihood ratio distance is used for distance calculation. Visualization of every step of speech recognition process (endpoint detection, speech pattern matching, decision making) is possible. Every speaker can create his own dictionary (collection of reference words) and use it for recognition. Recognition on-line mode is also available. One can press spacebar, say a word and result of recognition will be displayed on the screen. Another program "Palyginimas" is developed for recognition performance evaluation using speech databases. One can open lists of test and reference speech files and perform recognition experiments. Results of recognition has been displayed on the screen and finally written in text file. Using recognition results on the screen it is possible to evoke decision making results for particular decision. A number of recognition experiments was performed using this software. This research was supported by Lithuanian language in the information society 2000-2006 program. Related link:
