摘要: Recent enhancements to a connected speech recognition algorithm have led substantial improvements in accuracy especially for noisy environments. The performance are direct result of three features this algorithm: elimination priori endpoint detection; adaptation templates additive noise; and scoring using likelihood ratio. Experimental results provided which illustrate the both within-vocabulary substitution out-of-vocabulary rejection.
