使用 SSML 自定义文本转语音虚拟形象手势
包含输入文本的语音合成标记语言 (SSML) 确定了文本转语音输出的结构、内容和其他特征。 大多数 SSML 标记还可以在文本转语音虚拟形象中使用。 此外，文本转语音虚拟形象批处理模式通过使用格式为 <bookmark mark='gesture.*'/> 的 SSML 书签元素提供虚拟形象手势插入功能。
手势从插入时间点开始。 如果手势比音频花费的时间更多，则手势会在音频完成时间点被切断。
书签示例
以下示例演示如何使用 SSML 在文本转语音虚拟形象批量合成中插入手势。
<speak version="1.0" xmlns="http://www.w3.org/2001/10/synthesis" xml:lang="en-US">
<voice name="en-US-AvaMultilingualNeural">
Hello <bookmark mark='gesture.wave-left-1'/>, my name is Ava, nice to meet you!
</voice>
</speak>
在此示例中，虚拟形象将在说出“Hello”之后开始向左挥手。
