声学中的概念和形式常被用来举例说明量子力学。反过来，如Gabor的研究所表明的那样：量子力学也可以用来阐释新的声学观点。这里，我们特别关注人类声音的研究，因为人类声音被认为是探索声音世界的探测器。我们提出了基于发声观测的理论框架，以及一些可用于分析和合成的测量仪器。与描述粒子的自旋状态类似，量子力学的形式被用来描述与语音标签相关的基本状态之间的关系，如发音、湍流和声门上肌弹性振动。这些状态的混合和它们的时间演化仍然可以在傅里叶到伽柏的变化平面上解释，并且可以实现有效的提取器。因此本文提出了声量子声乐理论的基础，并对声的分析和设计有一定的启示。

原文题目：A Quantum Vocal Theory of Sound

原文：Concepts and formalism from acoustics are often used to exemplify quantum mechanics. Conversely, quantum mechanics could be used to achieve a new perspective on acoustics, as shown by Gabor studies. Here, we focus in particular on the study of human voice, considered as a probe to investigate the world of sounds. We present a theoretical framework that is based on observables of vocal production, and on some measurement apparati that can be used both for analysis and synthesis. In analogy to the description of spin states of a particle, the quantum-mechanical formalism is used to describe the relations between the fundamental states associated with phonetic labels such as phonation, turbulence, and supraglottal myoelastic vibrations. The intermingling of these states, and their temporal evolution, can still be interpreted in the Fourier/Gabor plane, and effective extractors can be implemented. The bases for a Quantum Vocal Theory of Sound, with implications in sound analysis and design, are presented.
