Micro-Application May Not Always Create Correct VoiceXML

Problem Summary The execution of Play Data (PD) Micro-Application may not always create VoiceXML as per the current VoiceXML and SSML built-in grammar types. This may lead to variations on expected spoken results when using TTS.
Error Message The TTS server bases its rendering of speech interpretation based on how we output these values, and it may not produce the exact output we are predicting or desire.
Possible Cause Configuration not in alignment with VoiceXML standards.
Recommended Action Change the say-as element and the interpret-as attribute to align them to the following standards in order to hear the desired output:

Voice Extensible Markup Language (VoiceXML) Version 2.0 (Specifically Appendix P): http://www.w3.org/TR/voicexml20/#dmlABuiltinshttp://www.w3.org/TR/voicexml20/#dmlABuiltins

Speech Recognition Grammar Specification (SRGS) 1.0: http://www.w3.org/TR/speech-grammar/http://www.w3.org/TR/speech-grammar/
