Source-filter synthesis 4. But the time scale is the original, except that the onset time of interval 1 is set to 0, unless the "Set initial time to 0" box in the startup window is unchecked.
In normal speech, the source sound is produced by the glottal folds, or voice box.
The audio example is 5 seconds long. A pitch target is the ideal f0 trajectory associated with a segmental unit, which is defined by three parameters: slope, height and strength. As a result, an object called "LPC hallo" will appear in the list of objects.
How to extract the source from an existing speech sound If you are only interested in the filter characteristics, you can get by with Formant objects.
Since the spectrum of a vowel spoken by an average human being falls off with approximately 6 dB per octave, pre-emphasis is applied to the signal before the linear-prediction analysis, so that the algorithm will not try to match only the lower parts of the spectrum.
