Twilio Autopilot crashing when I use SSML?

Question

I'm making a twilio autopilot project and I want to use SSML for the responses. Every time I trigger the intent that contains SSML, it crashes without anything showing up in the debugger. Here's what I'm doing:

{
"actions": [
    {
        "say":"<speak>Hi, how can I help you today?</speak>"
    },
    {
        "listen": true
    }
  ]
}

Please note (if this matters) that I'm using the console for my project.

What am I doing wrong? Is this not how you use SSML for autopilot? I'm not redirecting this to another function or anything fancy.

Thanks for the help!

Twilio Developer Evangelist here.

According to the Voice TwiML docs for SSML (separate from the Autopilot docs at the moment), when you’re using SSML with <Say> you can skip <speak> and insert rest of the SSML inside <Say>.

You could adjust the prosody of the text that is said in a phone call using SSML in your JSON file like this:

{
    "actions": [
        {
            "say": "<prosody rate='fast'>Speech Synthesis Markup Language (SSML) is a W3C specification that allows developers to use XML-based markup language for assisting the generation of synthesized speech.</prosody>"
        },
        {
            "listen": true
        }
    ]
}

Hope this helps!
