Synthesising human vocal sounds using subtractive synthesis

2 Synthesising human vocal sounds using subtractive synthesis 

In Chapter 4 we introduced the physiology of the human vocal mechanism from a physical modelling point of view. Here we will study the vocal tract from a subtractive synthesis standpoint. 

The pcmusic code for this voicing mechanism is given as follows  

Noise in the human voice corresponds to the generation of turbulence by the airflow past a constriction and/or past a relatively wide separation of the vocal folds. The resulting noise is called aspiration if the constriction is located at the level of the vocal folds i.e. the larynx. If the constriction is located above the larynx, the resulting noise is referred to as fricative. If it is produced by a relatively wide separation of the vocal folds then the resulting noise is called bypass. 

Rgure 6.8 The resonator component of the example instrument is composed of six band-pass filters
