A fundamental frequency estimation method for noisy speech based on instantaneous amplitude and frequency
This paper proposes a robust and accurate F0 estimation method for noisy speech. This method uses two different principles: (1) an F0 estimation based on periodicity and harmonicity of instantaneous amplitude for a robust estimation in noisy environments, and (2) an F0 estimation based on stability of instantaneous frequency as an accurate estimation method. The proposed method also uses a comb...
متن کاملRobust fundamental frequency estimation using instantaneous frequencies of harmonic components
This paper proposes a noise-tolerant method for fundamental frequency (F0) extraction. This method includes several new ideas, including the estimation of the instantaneous frequencies of the higher harmonic components, and the design of an adaptive weighting function based on a bandwidth equation that combines the F0 information in the harmonic components. To evaluate the proposed method, we c...
متن کاملFundamental frequency as basis for speech segmentation modeling
The present study investigates the relevance of fundamental frequency in speech segmentation models intended to simulate infants. Speech from three different conditions (infant-directed speech to 3and 12-month-olds, and adult-directed speech) was segmented based on fundamental frequency information, using a variant of the dpn-gram segmenting technique (highlighting similar segments as lexical c...
متن کاملUncertainty in fundamental natural frequency estimation for alluvial deposits
Seismic waves are filtered as they pass through soil layers, from bedrock to surface. Frequencies and amplitudes of the response wave are affected due to this filtration effect and this will result in different ground motion characteristics. Therefore, it is important to consider the impact of the soil properties on the evaluation of earthquake ground motions for the design of structures. Soil ...
متن کاملGuaranteed Estimation of Speech Fundamental Frequency with Bounded Complexity Algorithm
The first stage of the Pitch estimation for a short time speech signal analysis consists of an exhaustive search of all integer Pitch periods in the harmonic model. For each Pitch period the cost function is calculated and then optimized. The general complexity is proportional to N where N is the length of the window in samples. It is shown in this paper that the cost function can be approximat...
