Problem applying Orca settings in testing

Hi,

I'm running Debian testing with MATE, latest packages as of now, orca 
48.0-3, speech-dispatcher 0.12.0-2, espeak-ng-data 1.52.0+dfsg-5.
When I activate the Orca preferences with Orca+Space, then press Apply, 
I hear screen reader settings reloaded, then I have no more speech after 
that. The only way to fix it is to kill speech-dispatcher and press 
Alt+Super+S several times.

I'm using speech-dispatcher with eSpeak NG.

Thanks,
Tyler
