Abstract: Detecting the Pitch of singing voice in the presence of music is a challenging work to do. In this paper we study the problem of finding pitch range or value by analyzing the voice. We also review the vibratos and tremolos used to detect the singing voice. We just take review of detecting pitch from musical record and merits and demerits of pitch. Pitch is very important characteristic of voice and by detection it we can develop other different research works in voice processing field. We also study the advantages of pitch and its limitations. We can also study the future application that we can develop by using pitch. Pitch can be defined as the extent to which sound is high or low. It is the level of sound which may be high or low. It is also known as particular level of intensity of sound. Pitch detection is known as determining the level of intensity of voice. By using pitch we can detect various other characteristics of voice. We can develop many applications those are very useful for the benefit of human being or mankind. Pitch detection is crucial task in singing voice separation also. Pitch detection also play important role in Musical information retrieval, Identification of the singer and in lyric recognition. Pitch can identify gender of singing voice. It means it can identify the gender of the singer. Pitch also can examine or find the time of voice recording or the time slot of voice recording. So it is very much necessary to study pitch and its future work.
