In this paper, a fundamental frequency extraction method of noisy speech is proposed.
A p-th power amplitude spectrum is calculated with a band-limitation operation and
its noise counterpart is subtracted.
The resulting supectrum is inversely Fourier transformed, which is used
as the basis function for fundamental frequency extraction.
The p-th power is changed frame by frame based on a rule which is devived from a preliminary experiment on voiced speech.
It is shown that the new function invokes a performance robust against noise as well as formant characteristics.
Experimental results show that the proposed
method provides an improvement relative to the conventional methods particulary in highly noisy environments. |
