“…At the same time, were evaluated the MPT. The volunteers remained in orthostatic position with the Behringer ECM 8000 microphone (frequency response from 15 kHz to 20 kHz) join it to professional digital recorder (Zoom H4n; 96 kHz, 16 bits, with 50% of the recorder signal level), Fixed in a pedestal and positioned in front and at 90° angle of the mouth (23) , keeping the distance of 4 cm between the microphone and the mouth, to capture the emissions of the vowel (24,25,26) . They were instructed to, after a maximum inspiration, sustain during an entire expiration, with a normal pitch and loudness, the vowel /a/, which was recorder and measured by seconds.…”

“…From the calculation of the Kappa coefficient, in the analysis of the RASATI judges, the values found were 0.72 for judge 1; 0.56 for judge 2; 0.46 for 3; 0.38 for judge 4. In the VLE analysis, the values founds were 0.50 for judge 1, and 0.29 for judge 9,19,26 . The inter-assessor reliability of the three judges of RASATI was 0.31 and for the judges of the VLE, it was 0.2.…”

“…They were instructed to remain seated comfortably, keeping their back straight, feet flat on the floor and placing the proximal end of the tube between lips before issuing the phoneme / u: / 2,7,12 with no muscle effort of the shoulder girdle and the supra-hiodea, in usual pitch and loudness ( Figure 2). The issue of the phoneme / u: / occurred in a full expiration (in MPT) and each support was considered equivalent to a repetition, three sets of 15 repetitions were performed 9,18,19 . Posture, muscle effort and the correct execution of the technique were monitored visually by the speech therapist The RASATI scale was used, which aims to evaluate the parameters of hoarseness (R), roughness (A), breathiness (S), asthenia (A), tension (T) and (I) instability.…”
