Zero-crossing based spectral analysis and SVD spectral analysis for formant frequency estimation in noise

Abstract

This paper discusses a new method for spectral analysis of noise corrupted signals using statistical properties of the zero-crossing intervals. It is shown that an initial stage of filter-bank analysis is effective for achieving noise robustness of the technique. The new technique is compared with currently popular spectral analysis techniques based on… (More)
