Effects of Vocal Training on Singing and Speaking Voice Characteristics in Vocally Healthy Adults and Children Based on Choral and Nonchoral Data

Usefulness of Spectral Range Profile in Quantitative Assessment of Voice Quality in Adults and Children

“…However, the following main question remains: which of the methods and voice parameters are the most sensitive to voice training and could better quantitatively describe voice quality, as well as assess voice training effect. According to the literature, to achieve this purpose VRP along with SRP are proposed as relevant methods [4][5][6][10][11][12][13][14][15][16][17][18][19]. Findings of the present study support this opinion.…”

“…Several research works have shown that voice training has a quantifiable effect on voice capabilities, mostly on VRP parameters [4,[8][9][10][11][12][13][14][15][16][17][18][19]. Measurements derived from the VRP are useful in identifying voices which are well-equipped; in the diagnosis of vocal dysfunction; in suggesting starting points for voice training and in controlling training effectiveness or outcomes of the treatment.…”

“…Intraindividual variations of intensity parameters for the repeated assessments were within 2 dBA, and for frequency parameters -within 2 semitones with no statistically significant difference on the averages (P > 0.05). The identical voice measurements across test occasions were not expected as variations within individual voices would always seem to occur [11,14,30].…”

Acoustic and Respiratory Measures as a Function of Age in the Male Voice

“…They reported no significant differences in SFF between different elicitation tasks. Siupsinskiene & Lycke [29] investigated average speaking fundamental frequency for adult males and females. They reported that the range of SFF for men was 89.0-175.0 Hz with a mean of 112.4 Hz, while the range for females was 164.5-260.0 Hz with a mean of 212.4 Hz.…”

“…The average standard deviation of fundamental frequency (F0,SD) for both men and women is 25 to 30 Hz [25]. Using pitch sigma, Siupsinskiene & Lycke [29] reported that men have a range of 7.5 to 21.0 with a mean of 14.5 while females have a range of 5.2 to 16.1 with a mean of 10.7.…”
