Fundamental frequency, Pitch extraction, Noise robust
The fundamental frequency F0 is an important parameter for various methods of speech processing, including speech recognition and speech identification. In this paper, we present a simple but efficient method for tracking F0 in the time domain. Our approach is based on an autocorrelation function followed by correction with a smoothing operation that uses an estimated long-term pitch. This method performs well for both clean and noisy speech samples.
