My when testing my app I am getting "Error: Unable to parse the provided SSML". The provided text is not valid SSML." It looks good to me. I suspect some character (such as a smart quote) is an issue. I cannot find a list of valid characters for Alexa's SSML, nor can I find a validator. I'm not using IPA. I did not see a list of valid characters in the W3C SSMLdoc, but it seems to allow implementations to choose.
