Parallel Implementation of a Large Vocabulary Continuous Speech Recognizer Using OpenMP

method is employed in the emission probability computation for good load balancing. In the Viterbi search, however, we partitioned the search network into independent subtrees in offline to reduce memory synchronization overhead. The test was conducted using Wall Street Journal 20k evaluation and test set. We achieved the speed-up of 330% by utilizing four threads. The recognizer runs about 4.8 times faster than the real-time requirement.이 논문은 지식경제부 출연금으로 ETRI와 시스템반도체산업진흥센터에서 수행한 ITSoC 핵심설계인력양성사업과 교육과학기술부의 재원으로 한국학술진흥재단에서 수행하는 BK21 프로젝트의 지원을 받아 수행된 연구입니다
