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
|
|
1.4.2 RELEASE are included. The patch adds a new command to festival
|
|
(asterisk_tts).
|
|
|
|
|
|
2) You may wish to obtain and install the asterisk-perl
|
|
module by James Golovich <james@gnuinter.net>, from
|
|
either CPAN, or his site: http://asterisk.gnuinter.net,
|
|
as this contains a good example of how variable text
|
|
can be tts'd via asterisk, namely the examples/tts-*.agi
|
|
files there. It has been noted that the current expression
|
|
evaluation capabilities of asterisk are not best suited
|
|
for the generation and manipulation of text. AGI scripting
|
|
can be ideal for these sorts of needs. For simpler usage,
|
|
fixed, pre-recorded messages may be more amenable for your
|
|
purposes.
|
|
|
|
3) Before running asterisk, you have to run festival-server with a command
|
|
like :
|
|
|
|
/usr/local/festival/bin/festival --server > /dev/null 2>&1 &
