Sounds & languages
Where sounds live
| Path | Content |
|---|---|
/var/lib/asterisk/sounds/custom/ | sounds uploaded on Sounds (IVR, announcements, queues) |
/var/lib/asterisk/sounds/tr/ | Turkish system prompts shipped in sounds/tr/ of the repository |
/var/lib/asterisk/moh/ | music on hold |
/usr/share/asterisk/sounds/en/ | English prompts (Debian package) |
Debian's Asterisk searches prompts under /usr/share/asterisk/sounds. The installer links /usr/local/share/asterisk/sounds (Debian's custom directory) to /var/lib/asterisk/sounds/custom and /usr/share/asterisk/sounds/tr to /var/lib/asterisk/sounds/tr. Without these links IVRs, announcements and Turkish prompts fail with "File … does not exist in any format" and the call is hung up. The links live outside dpkg-owned files, so package upgrades keep them.
Sounds should be 8 kHz mono WAV (16-bit PCM). Uploaded files with the same name as a shipped file are never overwritten by updates.
Languages
A call uses the language set on its inbound route. When a prompt is missing in that language Asterisk plays the English one, so a partly translated set gives mixed-language prompts.
Turkish prompts
The Turkish set ships at the repo root as one package per format, asterisk-core-sounds-tr-<format>-<version>.tar.xz (with asterisk-core-sounds-tr-<version>.SHA256SUMS), laid out like Asterisk's own asterisk-core-sounds-* packages so it can be used on any Asterisk server: extract the formats you need into the tr sounds directory.
- One voice (Google
tr-TR-Wavenet-C), generated with AiPBX Cloud TTS from 16 kHz masters: every Asterisk core prompt (same names asasterisk-core-sounds-en, including voicemail, digits, letters, phonetic, conference, queue and directory prompts) plus AiPBX's own prompts. - Every prompt in six formats:
wav(8 kHz),ulaw,alaw,gsmand the wideband (HD)g722andsln16. Asterisk picks the one matching the call's codec, so no transcoding is needed. - Tones (
beep,ascending-2tone, …) come from the English set;silence/1..10are generated. - Licence: CC BY-SA 4.0 (tones: CC BY-SA 3.0, Digium).
Installs and updates extract the newest package into /var/lib/asterisk/sounds/tr/, replacing the prompts it contains (and removing other-format copies of the same names); other files in that directory are left alone.
To change a text, edit sounds/core-sounds-tr.txt (name|text), regenerate the masters (Google must be configured under AI → Cloud TTS) and rebuild the package:
sudo php web/bin/generate_tr_sounds.php --out=/tmp/tr-master # all prompts
sudo php web/bin/generate_tr_sounds.php --out=/tmp/tr-master vm-intro # or only some
scripts/build_tr_sounds.sh /tmp/tr-master 1.0.1build_tr_sounds.sh needs every prompt's master in the directory; to rebuild with only a few changed prompts, first extract the current package's .sln16 files back to WAV masters (sox -t raw -r 16000 -e signed -b 16 -c 1 NAME.sln16 NAME.wav).
Asterisk has no Turkish number/date grammar, so SayNumber, dates and voicemail message counts follow English word order; the texts are worded to stay natural in that order (e.g. vm-youhave = "Posta kutunuzda").
