I'm trying to install the Hello Speak example from the qt5 examples in Ubuntu 20.04, but i'm getting the following error in the console:

Job for speechd-up.service failed because the control process exited with error code.
See "systemctl status speechd-up.service" and "journalctl -xe" for details.

I've tried removing and re installing speak up and changing speech-dispatcher config but nothing worked.

I'd be glad if someone can help me resolve this issue.
