many results. My F0 analysis is done by bandpass filtering the time signal and then searching every
voice period in the time signal using my unique method. By searching in the time signal, each
voice period can be determined with high accuracy F0, and even small variations in the fundamental frequency can be seen. My unique F0 algorithm also makes it possible to determine the jitter and the shimmer.
My F0 algorithm has been in use for
39 years since
1984 and has been running in real time on the
NEC's µPD7720 signal
processor since
1985, 38
years ago. Analysis of images I have from the very beginning
coded Neon object-oriented programming language. Who else would have done
pitch analysis in Finland already on 1984, 39 years ago, and already on 1985 in real time? My F0 analysis I
have coded as a DSP man totally from zero to machine languages.
Computer Voice Field ™ (CVF) with ISA measured by prof. Aatto Sonninen
on 1987. The voice field shows each identified F0 period separately. The picture also shows the slope of the sound field.
