A study on Pitch Gross Error Improved with Segmented SNR Compensation
نویسندگان
چکیده
On speech signal processing, it is very important to find the fundamental frequency of voice. The reason is why it is used in variable places, such as speech-enhancement-system, speech-recognition system, speakerclassification-system, and handicapped assisting-system. However the pitch detection is difficult when the original signal is corrupted by noise, or put in transition section of voice. In this paper, we make proposal of the method that enhance accuracy of pitch detection system, through SNR compensation using continuous voice signal. And we proved the performance of the detector, in drawing pitch contour of variable SNR signals.

متن کاملIntelligent Control for the Variable-Speed Variable-Pitch Wind Energy System
In this paper, a new type of multi-variable compensation control method for the wind energy conversion systems (WECS) is presented. Based on wind energy conversion systems, combining artificial neural network (ANN) control and PID, a new type of PID NN intelligent controller for steady state torque of the wind generator is designed, by which the steady state torque output is regulated to track ...
متن کاملNoise tolerance in human frequency-following responses to voice pitch.
Speech communication usually occurs in the presence of background noise. This study examined noise tolerance in the brainstem's processing of voice pitch, as reflected by the scalp-recorded frequency-following response (FFR) from 12 normal-hearing adults. By systematically manipulating signal-to-noise ratio (SNR) across three different stimulus intensities, the results indicated that Frequency ...
متن کاملCompensation of Doppler Effect in Direct Acquisition of Global Positioning System using Segmented Zero Padding
Because of the very high chip rate of global positioning system (GPS), P-code acquisition at GPS receiver will be challenging. A variety of methods for increasing the probability of detection and reducing the average time of acquisition have been provided, among which the method of Zero Padding (ZP) is the most essential and the most widely used. The method using the Fast Fourier Transform (FFT...
