OPTIMIZATION METHODS FOR LARGE VOCABULARY , ISOLATED WORDS RECOGNITION IN ROMANIAN LANGUAGE

Speech recognition algorithms in general and isolated word recognition algorithm in particular are computationally intensive processes that consume a lot of time in an automatic speech recognition (ASR) system. This issue is in fact the bottleneck of real time ASR systems. This paper approaches the optimization of the recognition process by presenting an innovative three-step recognition method that diminishes the processing time for isolated words recognition. The recognition rate improvement is also approached by an adaptive technique of combining speech units.
