Figure 1From: Significance of parametric spectral ratio methods in detection and recognition of whispered speechTime domain waveforms (left) and Spectra (right) for the same speaker speaking ‘She had her dark suit in greasy wash water all year’ in neutral (top) and whispered (bottom) speech indicating shift of spectral energies from lower bands to higher bands spectrograms. Also addition of noise-like content and lack of harmonics can be observed for whispered speech.Back to article page
