AbstractThis paper explores the singing voice from an unusual perspective, not as a musical instrument but as a musical controller. A set of spectral processing algorithms extract features from the input voice. These features are categorized in four groups excitation, vocal tract, voice quality, and context. The extracted values are then transmitted as Open Sound Control (OSC) messages to be used in an external synthesis engine. In this paper, we provide first a technical description of the algorithms, and in a second part, we detail the components of the system. A practical example of voice-driven synthesis using PureData (Pd) is also presented.
