问题
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!
