Pitch estimation of Marathi spoken numbers in various speech signals

This paper describes pitch estimation of Marathi spoken numbers which are extracted the features from various speech signals. The speech frequencies of Marathi spoken numbers are acquired by various male and female speakers. The pitch frequencies are normalized using PRAAT tool. The pitch contours are compared with pitch detector. The autocorrelation and cepstral methods are used to estimate speech frequency. Pitch detection is calculated by statistical methods and similarity is measured by Euclidian distance. The pitch frequency results found to be satisfactory. The average mean of frequency varies from 1.48 to 2.03 and standard deviation varies from 0.84 to 1.38 in Hz.
