How Do I Enable Spoken Word and Other Sound Options On the Accessibility Keyboard?

I am a disabled user and even though I can type (slowly) I use this with my mouse to play on a Minecraft roleplaying server where there is an extraordinary amount of things to be typed. I have an entire panel just for the server. However, I am not sure how to activate the Spoken Word and sound function. Spoken Word never works and Sound (on press) is always greyed out. Do I have to disable the default press key sound to get sound to work? I have never gotten Spoken Word to work even with dictation or TTS on. Any help would be appreciated. I’ve been working on this issue a long time. I’m on iMac 27″ Late 2013 running Mojave. Thanks!
