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.

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!
