Just experienced this bug today. It seems to be triggered by certain websites. I'm not using any feature of speech-dispatcher. Until I experienced this issue I was unaware of it's existence as a daemon. Running killall speech-dispatcher corrects the issued temporarily as others have said. The problem reoccurs quite frequently however. I have no use for speech-dispatcher so I have simply uninstalled it. It's quite unfortunate that this bug exists in the default install of Ubuntu 20.04. Is nothing really going to be done to fix this?
