My description of the sound for the 8A Peer Assessment of the ASPMA Coursera course:
The analysis parameters are window='blackman', M=1201, N=4096, t=-90, minSineDur=0.05, nH=70, minf0=100, maxf0=350, f0et=5, harmDevSlope=0.1, stocf=0.1.
Frequency scaling factors: [0,2.7,1.9,2.7,1.91,3.1,3.28,3.1]
I tried to get a female child voice. Then I scaled the frequencies by high factors, and even higher the ones of the last part in order to get a small expression of shyness or embarrassment.
Frequency stretching factors: [0,1,1,1] (no change)
Timbre preservation: 1 (no change)
Timbre scaling factors: [0,0, 0.7,0.5, 0.75,0.51, 1.37,1.07, 1.9,1.4, 2.28,1.58, 2.6,1.8, 2.67,1.81, 3.28, 2.38]
I change this in order to get a more natural higher speed, mainly in the last part of the speech, in particular compressing the "silent" spaces.
