Evolution of glottal flow derivative spectrum according to E and T. In green are the spectra of the glottal formant only. The glottal formant filter’s frequency response is indicated with a thick green line as the envelope of the glottal formant’s spectrum. In blue is the overall glottal spectrum including glottal formant and spectral tilt. The overall frequency response is represented with a thick blue line as the envelope of the overall glottal spectrum. Top row: low vocal effort (E=0.2); bottom row: high vocal effort (E=0.9); left column: low tension (T=0.2); right column: high tension (T=0.8). These spectra have been calculated for M=1 and f 0=100 Hz
