[Freeswitch-users] Inserting pause on "say" iterated name_spelled?

[Johny Kadarisman Kwan]

When using "say" function :

           <action function="say" data="1234" method="iterated"
type="name_spelled"/>

I just feel like the spelling between that number a bit fast. Is there a
way to insert pause between the number spelled?

I supposed can change each number sound file to include silent, but looking
for a better way.
