I am trying to install MaryTTS 5.2 on Ubuntu 16.04. There is a guide on for 5.1.2 here . However, 5.2 is way different, and I do not understand the installation guide on their GitHub page.
The first command fails when executed inside the unpacked 5.2 folder:
marytts install:cmu-slt
--->marytts: command not found
Can someone please help?
