dectalk with Zabbly?

Hi All: After upgrading to the latest Zabbly 6.18.9, we had the following 
discovered by my Linux expert
The speakup_dectlk module is set to load on boot in the modules.d directory
conf file. The problem seems to be that the simple speakup_dectalk
reference is not found. When I have to insmod the ko file, I have to use
full path in comparison to just using the reference.
Back again live. At first we thought they changed from modprobe to insert mod? 
I wouldn't know if this were specific to Zabbly or 6.18.9? Thanks in advance 
for any guidance. O, Samuel, please inform what other steps we need to perform 
to run this DecTalk in USB? We tried running that command you mentioned, but 
nothing happens.
