AB  - Estimation of instantaneous pitch provides high accuracy for frequency-modulated pitches and can be beneficial compared to conventional pitch extraction techniques for unsteady voiced sounds. However, applying an estimator of instantaneous pitch to a practical real-time speech processing application is a hard problem because of high computational cost and high inherent delay. The paper presents an algorithm for instantaneous pitch estimation specifically designed for real-time applications. The analysis scheme is based on the robust algorithm for instantaneous pitch tracking (IRAPT) featuring an efficient processing scheme and low inherent delay. The paper presents some evaluation results using synthesized and natural speech signals that illustrate actual performance of the algorithm.
