Formant Synthesis

Categories: Speech

Author(s): Steve Isard

Basic sounds of a language can be characterised by their Formant frequencies. The formant pattern for a synthetic utterance can be created by interpolating between the formant values of the sounds composing the desired utterance. A speech wave can be computed from such a formant pattern, to be played through a digital-to-analogue converter, or the formant pattern can be used directly to excite a set of resonators, acting as an electrical analogue of the vocal tract.
