Concepts and formalism from acoustics are often usedto exemplify quantum mechanics. Conversely, quantummechanics could be used to achieve a new perspective onacoustics, as shown by Gabor studies. Here, we focusin particular on the study of human voice, considered asa probe to investigate the world of sounds. We presenta theoretical framework that is based on observables ofvocal production, and on some measurement apparatithat can be used both for analysis and synthesis. Inanalogy to the description of spin states of a particle,the quantum-mechanical formalism is used to describethe relations between the fundamental states associatedwith phonetic labels such as phonation, turbulence, andslow myoelastic vibrations. The intermingling of thesestates, and their temporal evolution, can still be interpretedin the Fourier/Gabor plane, and effective extractors canbe implemented. This would constitute the basis for aQuantum Vocal Theory of sound, with implications insound analysis and design.
