This article presents the results of collaboration between a composer and researchers in the context of vocal roughness and composing for voice. Our research focused on parametric control of distortion. Specifically, we present a software device that supports the manipulation and control of vocal roughness in real time, using a method based on amplitude modulation and filtering. The compositional interest in working with classically trained opera singers and with vocal distortion led us to initiate research in the signal-processing domain. Our goal was to develop a tool that could facilitate the production of distorted sounds without direct effort on the part of the singer. In this way, the singer can perform a nondistorted or lightly distorted sound, and the software tool will generate or magnify the distortion in real time.

合成人声失真：实时生成粗糙度的工具

本文介绍了作曲家和研究人员在人声粗糙和人声作曲的背景下合作的结果。我们的研究集中在失真的参数控制上。具体来说，我们提出了一种软件设备，该设备支持实时操纵和控制人声粗糙度，使用基于幅度调制和滤波的方法。与受过古典训练的歌剧歌手合作和人声失真的作曲兴趣使我们开始了信号处理领域的研究。我们的目标是开发一种工具，无需歌手的直接努力即可促进失真声音的产生。这样，歌手就可以演奏出不失真或轻微失真的声音，软件工具会实时生成或放大失真。
