本文为您展示了语音通知功能的实现方法。您可以通过调用SingleCallByVoice发起语音文件类型的语音通知，调用SingleCallByTts发起文本转语音类型的语音通知。

功能介绍

语音通知可解决通知到达率延迟、关注度不高、阅读体验差等问题，并且您可以通过电话获得更全面的信息通知。您只需要提前设置通知模版内容，调用API就可以给用户推送语音通知，并可以设置播放音量、播放次数等。

准备工作

在实现调用API实现语音通知功能前，您需要完成以下操作：

代码示例

本示例展示了如何调用SingleCallByVoice接口发送语音通知。接口参数详情，请参见SingleCallByVoice和SingleCallByTts。

如果您需要进行调试，请参见使用OpenAPI Explorer。
