Echo speaks All Voice Output Blocked... Do Not Disturb is ON

Wish I could help, but I am not an Echo Speaks user. I am tagging @tonesto7, the author of Echo Speaks.

In general, it is usually best to present an issue like this in the thread specific to the Community App/Integration in question. This way, there will be plenty of other knowledgeable users who will get notified, including the developer of the app.
