[Freeswitch-users] How to escape double-quote in dialplan and use TTS SSML tags

[Michael Collins]

How about using CDATA? Like this:

<action application="set"><!CDATA[args=<voice emotion="calm"><emphasis>This
is to test our text-to-speech system.</emphasis></voice>]]</action>
<action application="speak" data="${args}"/>

That's just off the top of my head so please tinker with it if it doesn't
work on the first try.
