* Consistently use spaces in rest-api-templates/asterisk_processor.py. * Exclude third-party from docs/full-en_US.xml. * Add docs/full-en_US.xml to .gitignore. * Use list() to convert python3 view. * Use python3 print function. * Replace cmp() with equivalent equation. * Replace reference to out of scope subtype variable with name parameter. * Use unescaping triple bracket notation in mustache templates where needed. This causes behavior of Python2 to be maintained when using Python3. * Fix references to has_websocket / is_websocket in res_ari_resource.c.mustache. * Update calculation of has_websocket to use any(). * Use unicode mode for writing output file in transform.py. * Replace 'from swagger_model import *' with explicit import of required symbols. I have not tested spandspflow2pcap.py or voicemailpwcheck.py, only the print syntax has been fixed. Change-Id: If5c5b556a2800d41a3e2cfef080ac2e151178c33
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).
It is possible to run Festival without patches in the source-code. Just
add this to your /etc/festival.scm or /usr/share/festival/festival/scm:
(define (tts_textasterisk string mode)
"(tts_textasterisk STRING MODE)
Apply tts to STRING. This function is specifically designed for
use in server mode so a single function call may synthesize the string.
This function name may be added to the server safe functions."
(let ((wholeutt (utt.synth (eval (list 'Utterance 'Text string)))))
(utt.wave.resample wholeutt 8000)
(utt.wave.rescale wholeutt 5)
(utt.send.wave.client wholeutt)))
[See the comment with subject "Using Debian
festival >= 1.4.3-15 (no recompiling needed!)" on
http://www.voip-info.org/wiki-Asterisk+festival+installation for the
original mentioning of it]
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 &
