if I use
<action application="speak"
data="cepstral|david|<prosody volume='65'>Your credit is too low to reach
the landline user phone. Transfer to
voicemail.</prosody>"/>
it seems that SSML isn't supported like this,
the voice says "/ prosody" only. the whole sentence is not
said.
do I escape the SSML code in the data ?
Thanks
