My degree thesis is focusing on the topic of ¡°Study and comparison of the algorithms for pitch determination in Speech Recognition¡±. During these 3 weeks, I was studying on the basic theories of Speech Recognition, reading related chapters in two books as well as four reference papers. A rudimentary picture of speech recognition comes up in my mind and here I would make a brief review in order to carry out following research.

The speech signal is a non-stationary stochastic process. Because of this time-variant characteristic, we should divide the signal into short segment sequence, with one segment called a frame, often 5~50ms for general applications. In each frame, the signal can be deemed as stationary so that some existent theories of signal processing can be used to analyze the speech.

There are two types of speech sound called Unvoiced and Voiced. The voiced sound has periodicity to some extent while an unvoiced one is nearly random noise. The periodicity sets the pitch of a voiced sound. The difference between the voiced and unvoiced plays an important role in pitch determination, aiming at detection of the periodicity of the voiced sound and thus recognizing or synthesizing the produced sound.
