A unified source-filter model describes human and synthetic voice alike

Evidence

This chapter has been devoted to human voice as a communication signal; how it is produced by humans and technical systems. The modelling aspect is used here to characterize the general principles that are, in most cases, common to human voice production, the acoustic generation of sound, and to the electronic and computer means of generating voice in technical devices. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 633
