A Summarize of Pitch Detection Algorithmic in Speech Signals Processing

Pitch detection is a basic topic in speech signals processing. Through many years’ research, there is yet a satisfied technology in terms of accuracy and robust. When the speech is clean, most of the pitch detection algorithms are fine, but many technologies are not satisfied when the speech mixed with noise or the speech is a mixture of multi-speech. This paper introduces some mainstream pitch detection algorithms, and discusses the improvement of these algorithms.
