Terminal, say, problem with voice -v "Daniel"

Hello,

When I use command say in Terminal, I get the following problem:

% say -v Daniel "whats up" 
Open speech channel failed: -108

This error occurs only with the voice "Daniel", all the other voices work correctly and I hear the speech, e.g.

% say -v "Alex" "whats up"

Has anyone else met similar problem or may know a solution to this?

I'm using Macbook Air with macOS Big Sur, Version 11.5.2

With Best, Petri
