This paper focuses on the role of frequency spectral tilt (TL) of the voicing source waveform, the glottal turbulent noise and fluctuations of the source spectrum on period-to-period basis in the cognition of paralinguistic features as in suspicious and disappointed renditions. The TL is closely related to duration of the return phase of the differentiated glottal waveform. Perceptual experiments have shown that the larger the TL, the lower the degree of suspicion and existence of the source spectral fluctuations increases that degree over the entire range of the TL. In the case of disappointment, the larger the TL, the higher the degree of disappointment and inclusion of the glottal turbulent noise emphasizes disappointment when the TL is small.
