Hi,
Asterisk crashes if one choose a non-existing voice.
The proposed patch may fix it.

Regards

My Asterisk won't response for a while after run the TTS for the first time. Also the TTS won't work anymore.

Hi,

Last formal release was in 2011, and I notice some commits since then.

Please consider make a formal release.

I've tried by installing Asterisk 13 on Debian 9 these packages: asterisk asterisk-espeak
But when just diaplan runs:
same => n,Espeak("deje su mensaje",any,es)
then Asterisk console shows:
[Jul 31 14:17:14] ERROR[13903][C-00000000]: app_espeak.c:352 espeak_exec: eSpeak: Failed to set capind=0. Same behaviour

After that the call is terminated.

With asterisk-18.10 I get following error when loading the app_espeak.so module from zaf-Asterisk-eSpeak-7431b8d
