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

[Stefan R. <sr...@re...>]

Darren,

it looks like you are always using TTS to generate the voice files for
your application even if they are rathe static. I would only run the TTS
once (outside of your AGI scripts) and then use the generated voice
files. If you have dynamic parts (like greeting the user with his name)
I would only render those parts at run time. This should eliminate the
delay and take away some load from your Asterisk server.
