RE: [Asterisk-java-users] Text-to-speech and gathering data (fastAGI)

[Darren H. <dha...@gh...>]

Thanks Stefan,
My intent is actually to optimize the second part of non-static
requests.  This test does indeed could used pre-generated voice files
(per the cached remark), but the intent is to identify the best way to
handle the dynamic parts.

Is this the best way to handle dynamic tts parts?=20
