app_festival is an application that allows one to send text-to-speech commands
|
|
to a background festival server, and to obtain the resulting waveform which
|
|
gets sent down to the respective channel. app_festival also employs a waveform
|
|
cache, so invariant text-to-speech strings ("Please press 1 for instructions")
|
|
do not need to be dynamically generated all the time.

|
You need :
|
|
|
|
1) festival, patched to produce 8khz waveforms on output. Patch for Festival
|
|
1.4.1 RELEASE are included. The patch adds a new command to festival
|
|
(asterisk_tts).
|
|
|
|
2) My patches to asterisk that provide variable substitution and quoting to
|
|
the Asterisk Extension Logic. This is not really a requirement, but without
|
|
this, app_festival is mostly useless (you could very well use prerecorded
|
|
voices for static information).
|
|
|
|
3) Before running asterisk, you have to run festival-server with a command
|
|
like :
|
|
|
|
/usr/local/festival/bin/festival --server > /dev/null 2>&1 &
