A Tutorial on Hidden Markov Models and Selected Applications in Speech Recognition. It is a powerful tool for detecting weak signals, and has been successfully applied in temporal pattern recognition such as speech, handwriting, word sense disambiguation, and computational biology. 77, No. recognition" (ASR), "computer speech recognition", or just "speech to text" (STT). Figure 1: Classification 1 dialogues. Speech Recognition : Speech recognition is a process of converting speech signal to a se-quence of word. A Tutorial on Hidden Markov Models and Selected Applications in Speech Recognition LAWRENCE R. RABINER, FELLOW, IEEE Although initially introduced and studied in the late 1960s and early 1970s, statistical methods of Markov source or hidden Markov modeling have become increasingly popular in the last several years. HTK is primarily used for speech recognition research although it has been used for numerous other applications including research into speech synthesis, character recognition and DNA sequencing. The Hidden Markov Model Toolkit (HTK) is a portable toolkit for building and manipulating hidden Markov models. Since speech has temporal structure and can be encoded as a sequence of spectral vectors spanning the audio frequency range, the hidden Markov model (HMM) provides a natural framework for Hidden Markov Models for Speech Recognition B. H. Juang and L. R. Rabiner Speech Research Department AT&T Bell Laboratories Murray Hill, NJ 07974 The use of hidden Markov models for speech recognition has become predominant in the last several years, as evidenced by the number of published papers and talks at major speech conferences. The core of all speech recognition systems consists of a set of statistical models representing the various sounds of the language to be recognised. Various approach has been used for speech recognition which include Dynamic programming and Neural Network. Genmark: Parallel gene recognition for both dna strands. A hidden Markov model (HMM) is a statistical Markov model in which the system being modelled is assumed to be a Markov process with unobserved Proceedings of the IEEE, 77(2):257–286, February 1989.
