Objective: To correlate vocal measures after percipient-auditory acoustics and of glottic source Finger Kazoo (FK). Method: Analysis of the /a vowel: /of 46 adult women without vocal complaints or laryngeal conditions for the Dimensional Multi Voice Program Advanced® and RASATI scales, before (M1) and after (M2) three series of the FK and five minutes after silence (M3). Test Kappa, Friedman, Wilcoxon and Spearman. Results: Significant increase of the basic frequency (f0), reduction of the amplitude variation (vAm) and degree of sub-harmonic (DSH) in M2. RASATI without significances. Significant positive correlations: shunting line-standard f0 (STD) with soprosity and asthenia; measures of jitter, variation of frequency (vf0) and index of soft speech (SPI) with hoarseness, soprosity, asthenia and instability; measures of shimmer and vAm with hoarseness and soprosity; vAm with asthenia; degree and number of segments not sound (DUV and NUV) with soprosity; STD, jita, SPI, quotient of disturbance of pitch alleviated (sPPQ), quotient of disturbance of the alleviated amplitude (sAPQ), vf0 and vAm with instability. Significant negative correlations: index of turbulence (VTI) with asthenia; measures of jitter and SPI with tension; f0 more acute (fhi), f0 more serious (flo) and f0 with hoarseness and soprosity; instability with flo. Conclusions: The FK generated reduction of the noise, increase of f0, the vocal stability and the harmonic energy. In the generality, hoarseness, asthenia, soprosity and instability had been correlated positively with measures of jitter, shimmer, STD, SPI, vf0, vAm, NUV, DUV and negative with the measures of frequency and VTI. The tension was correlated negative with the measures of jitter and SPI.
