asterisk users - Jun 2004 - Festival application: clipping start of sound?

Hi

I'm running a bright shiny new asterisk installation, and have
discovered a problem with the festival application - when it plays back
the generated sound, it skips the start.  If, on the other hand, it has
caching turned on, then when it plays the cached sound, it doesn't skip
the first word or two.  I assume that this has something to do with the
time taken to generate the speech - is there anything I can do about
this, apart from getting a faster machine for festival?

Also, files in the festival cache directory seem to be created with mode
0000.  Is there any setting I need to prod to make them readable by
asterisk?  I'm running the debian packaged asterisk.

thanks

donald

IMHO the Festival application is slightly broken since it doesn't interface 
to the asterisk playback routines in a standard way.  I've never had much 
luck with caching but have experienced the problem you outline on direct 
text conversions.  This issue has been discussed on the bug tracker and 
this list in the past.

You can hack Festival to pad out the pokayback with silence so the silence 
gets chopped before your sound.  You can also have Festival save the sound 
file and then play back the sound using asterisk's standard playback 
routines.  Both work but they're not nice solutions and add some latency,
