The Viterbi algorithm is a powerful dynamic programming method for determining the hidden state sequence that is most likely to exist in a hidden Markov model (HMM). The algorithm is frequently used for speech recognition, part-of-speech tagging, and DNA sequence analysis. It is named after its creator, Andrew Viterbi.
