Customize text to speech avatar gestures with SSML
The Speech Synthesis Markup Language (SSML) with input text determines the structure, content, and other characteristics of the text to speech output. Most SSML tags can also work in text to speech avatar. Furthermore, text to speech avatar batch mode provides avatar gestures insertion ability by using the SSML bookmark element with the format <bookmark mark='gesture.*'/>.
A gesture starts at the insertion point in time. If the gesture takes more time than the audio, the gesture is cut at the point in time when the audio is finished.
Bookmark example
The following example shows how to insert a gesture in the text to speech avatar batch synthesis with SSML.
<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>
In this example, the avatar will start waving their hand at the left after the word "Hello".
