Sofoklis Kakouros, Okko Räsänen, Paavo Alku

Abstract: Highlights•The role of spectral tilt in sentence prominence was investigated.•Estimators for tilt of glottal source spectrum and surface spectrum were compared.•Multidimensional representations for spectral tilt were also investigated.•Robustness of different tilt estimators was tested for noisy and coded speech.•Experiments were conducted on both French and Dutch speech data.
