Slow down Twilio's TwiML “Say” command for standard text on text-to-speech

How can I slow down a normal content inside the "Say" verb? The spanish accent is VERY fast and most people have trouble following/understanding what is said. Ideally something like the following would be perfect:

<Say voice="woman" language="es" speed="0.5">El siguiente mensaje se repetirá en español</Say>

Note I made up the speed="0.5" param. That is not an option for twilio but slowing the reading of the content of that "Say" verb by half is what I am looking for.

I don't think this is currently supported in any explicit way so ideas on how to accomplish this more hackish are welcome too. Text is dynamic.

Thank you for your insight.

  • Friendly Neighbourhood Twilio Evangelist here:

    Could I suggest you use Twilio's new voice, 'Alice', I think she sounds a lot better, but I'm afraid I don't speak Spanish so it's difficult to test:

    <Say voice="alice" language="es-ES">...</Say>

    Hope this helps!
