Formant frequencies were estimated from spectra of the vowel samples. LTAS was made and equivalent sound level (Leq) was measured for the text samples. Formant frequencies were used as the input for a 1D mathematical model. After the exercise, the peak at 3.5 kHz in the LTAS of the reading samples was stronger, although Leq was the same as before, suggesting a level-independent resonance change. Reading samples after exercising were evaluated to sound better in voice quality than before exercising. The strong peak at 3.5 kHz was present in all vowels, and it was mainly formed by clustering of F4 and F5. A 1D model-based optimization suggested that this kind of a formant cluster could be best established by simultaneously narrowing the epilaryngeal tube, widening the pharynx and narrowing the front of the oral cavity.
