    Abstract: PURPOSE: A pitch estimating system using an interpolation method in a time-frequency mixing domain is provided to use the interpolation method when a time domain is mixed with a frequency domain. CONSTITUTION: A second autocorrelator(520) outputs an autocorrelated value of a frequency domain. A first interpolator interpolates an autocorrelated value of a time domain. A second interpolator interpolates the autocorrelated value of the frequency domain. A pitch estimator(540) applies a weighted value to the interpolated autocorrelated value of the time domain and the interpolated autocorrelated value of the frequency domain. The pitch estimator estimates a final pitch.

    Abstract: PURPOSE: A pitch estimating system of a time-frequency combining area using salience and a method thereof are provided to estimate a pitch using salience of a frequency domain. CONSTITUTION: An autocorrelator(110) calculates an autocorrelated value of a time domain about a voiced sound signal. A salience detector(120) detects salience of a frequency domain about the voiced sound signal. A pitch estimator(130) applies a first weighted value to the salience and the autocorrelated value in the time domain. The pitch estimator combines the autocorrelated value with the salience. The pitch estimator estimates an index of the maximum peak of the combined signal as a pitch.
