[asterisk-users] Cepstral/Swift TTS app

[will at loopfree.net]

Hey everyone,

I was frustrated with the existing app_cepstral/app_swift TTS modules I've
found on the net, so I hacked up my own. It's been working really well for 
me so I thought I'd share.

In developing this, I wanted to avoid:

* the startup delay incurred writing TTS output to a temp file then playing 
it back
* gluing cepstral/swift to the asterisk module in a way that fubard the
cepstral licensing server concurrency count

And I wanted to support:

* configurable in-memory buffering so you can balance how "far ahead" swift
will get in generating audio. So you can trade off swift process
concurrency vs memory use.
* hanging up or exiting the speech call with DTMF is handled quickly and 
gracefully

If anyone can make use of this, great! Or let me know if it's horribly 
broken. All I can say at this point is that it works really well for me in 
a TTS/IVR system I'm developing.
