Hi, I'd like to add SSML tag to my TTS string. I am sure my TTS server supports these tags. In this example, <action application="speak" data="<voice emotion="calm"><emphasis>This is to test our text-to-speech system. </emphasis></voice>"/> Whether I use <voice emotion="calm"> or <voice emotion=\"calm\"> FS complains: unexpected closing tag </voice> If I use single quote like <voice emotion='calm'>, FS starts ok but TTS will read out the string of <voice emotion='calm'> And I notice that this string is still read out even if it is passed as double quoted ( <voice emotion="calm"> ) through my ESL app. Any advices for using SSML in unimrcp TTS string?
