Hello all. I am pretty new to Freeswitch and have an experimental container
on Proxmox 6.3 Debian 10 to play with. The goal is to get mod_unimrcp
working. To that end, I have mod_tts_commandline (installed from binary
with FusionPBX as part of the default install) listed in modules.conf.xml
/etc/freeswitch/autoload_configs/modules.conf.xml
<!-- Speech Recognition / Text to Speech -->
<load module="mod_unimrcp"/>
<load module="mod_tts_commandline"/>
<load module="mod_flite"/>
I have tried it with and without mod_flite enabled.
Mod_tts_commandline refuses to pull a sound file and the debug log seems to
blame mod_sndfile. This is using the example from the mod_tts_commandline
page
<https://freeswitch.org/confluence/display/FREESWITCH/mod_tts_commandline#mod_tts_commandline-Configuringmod_tts_commandline>
as dialplan shows following the debug log output below:

The dialplan for extension I am testing looks like this:
<extension name="tts_commandline_test">
<condition field="destination_number" expression="^561$">
<action application="speak" data="tts_commandline|pico|This is

</condition>
</extension>

The code lines mentioned in debug seem to be pretty mundane, not that I
really know what I am looking for:
From mod_tts_commnandline line 160:
switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_DEBUG, "Executing:
%s\n", message);
I tried setting the /tmp directory to 777 but that didn't help and the
error output was identical. mod_tts_commandline never reports an error
on
creation and it looks like the next part of of mod_tts_commandline
would print an error if it did like this:
if (switch_system(message, SWITCH_TRUE) < 0) {
switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Failed to
execute command: %s\n", message);
ret = SWITCH_STATUS_FALSE; goto done;
}
if (switch_core_file_open(info->fh, info->file, 0, //number_of_channels,
info->rate, //samples_per_second,
SWITCH_FILE_FLAG_READ | SWITCH_FILE_DATA_SHORT, NULL)
!=SWITCH_STATUS_SUCCESS) {
switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Failed to
open file: %s\n", info->file);
ret = SWITCH_STATUS_FALSE; goto done;
}

Starting at line 279 in mod_sndfile (sorry for the space formatting):

if (!context->handle) {
if (sndfile_perform_open(context, path, mode, handle) !=
SWITCH_STATUS_SUCCESS) {
switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_WARNING, "Error
Opening File [%s] [%s]\n", path, sf_strerror(context->handle));
status = SWITCH_STATUS_GENERR;
goto end;
}
}

According to the dptools docs
<https://freeswitch.org/confluence/display/FREESWITCH/mod_dptools%3A+playback#mod_dptools:playback-3.1>
and libsndfile wav has been supported forever and it would seem highly
unlikely that is an issue. It seems like mod_tts isn't writing the
file but also isn't reporting an error. I have started fresh with two
new containers twice and a full VM once all with the same error
resulting. I check the /tmp directory and no files are present but I
don't know if they are being deleted by some cleanup process or just
not created. Not knowing C, it seems like mod_sndfile never received a
file handle but that is just a guess. Other Freeswitch apps are
writing to the /tmp directory (at least there are some files in
there). Maybe someone sees an error from mod_tts_commandline I don't
see or knows I am doing something stupid. Any help would be
appreciated. I only found 2 references to the error in the mail
history and neither had anything to do with a similar issue.

If the wav file exists but is 0 size, mod_sndfile would say this:mod_sndfile.c:281 Error Opening File [/tmp/foo.wav] [File contains data in an unknown format.]

So yes, most likely text2wave is not installed.

That was exactly it for the record.

Thanks for the help.
The reason I tried to start with tts_commandine is I have been
struggling for a couple of weeks to get MRCP to produce something
useful so I thought I would try something simpler and I could swear
mod_tts_commandline was listed as a requirement. But it could have
been on something else as I have been pouring through every document I
can find to figure this out and I probably got confused.
Thanks again!

Thanks so much! That is very helpful info. Let me create a new thread
for this and explain what I have done so far.
