The LVCSR systems are developed for several decades. Nowadays LVCSR system take advantage of increasing performance of computers and sophisticated algorithms. There is permanent effort to integrate larger lexicons into LVCSR system. A n-gram language model can improve recognition accuracy. However, memory requirments are substantial, so in practise for real-time implementation of LVCSR system only a bigram language model is often considered. The LVCSR system can be used for either automatic dictation or as speech recognition module (for voice dialog system) loosely coupled with a speech understanding module. The output of the LVCSR system is either a word lattice, or the best sequence of words matching the input acustic signal. The word lattice can be processed by higher level blocks.
