生成包含多个发言人的对话

注意：此功能仅适用于许可清单中的项目。如果您想使用此功能，请与我们联系。

本页面介绍了如何创建包含多个发言人且由 Text-to-Speech 创建的对话。

您可以使用多个发言人生成音频，以创建对话。这对于访谈、互动式故事讲述、视频游戏、在线学习平台和无障碍解决方案非常有用。

以下语音支持多发言人音频：

• en-US-Studio-Multispeaker
  • 发言人：R
  • 发言人：S
  • 发言人：T
  • 发言人：U

示例。此示例是使用多个发言人生成的音频。

注意：此功能最多支持两个发言人。此语音处于实验阶段，不在语音列表中。

示例：如何使用多发言人标记

此示例演示了如何使用多发言人标记。
