摘要

本文提出了一种将时频插值(TFI)应用于韵律语音修饰的方法。描述了语音信号时频域表示的基本概念。提出了一种基于同步TFI的系统，并给出了该系统在时间和音阶修正中的应用实例。进行非正式的主观测试。他们强调了该系统与时域基音同步重叠和添加(TD-PSOLA)语音合成技术相比的优越质量。

Prosodic speech modifications using pitch-synchronous time-frequency interpolation

This paper presents a method to apply time-frequency interpolation (TFI) to prosodic speech modifications. The basic concepts of representing the speech signal in the time-frequency domain are described. A system based on synchronous TFI is proposed, and application examples of this system to time and pitch scale modifications are presented. Informal subjective tests are performed. They highlight the superior quality of the proposed system in comparison with the time-domain pitch synchronous overlap and add (TD-PSOLA) technique of speech synthesis.
