The effect of the flow mask on phonation
نویسندگان
چکیده
presence of the flow mask affects voice quality. Microphone and flow recordings were inverse filtered and were compared to examine the possible effects of the flow mask. Closing quotient (ClQ), open quotient (OQ) and the amplitude difference between the first and second harmonics (H1-H2) were the parameters used to characterise the inverse filtered signals. The presence of the flow mask used for the recording of oral flow had an effect on these parameters, which is interpreted as being indicative of a more tense or more efficient voice quality in the presence of the mask.

Seventeen healthy women, 45 to 61 years old, were examined using videofiberstroboscopy during phonation at three loudness levels. Two phoniatricians evaluated glottal closure using category and ratio scales. Transglottal airflow was studied by inverse filtering of the oral airflow signal recorded in a flow mask (Glottal Enterprises System) during the spoken phrase /ba:pa:pa:pa:p/ at three loudn...
