I am planning to use my mac for Indigo and for music playback from Spotify. The mac is connected to an amp (placed in an other room with a set volume), and the volume of music is controlled within Spotify.
As a result every voice synthesis speaks at maximum level. I don't want to reduce the main volume / system volume on the mac because then the music will not be able to play loud enough.
Is it possible to change the volume of 'speak' / voice synthesis?
As a new user I have not found a way yet. The only way I found is to use the Announcer plugin instead of the native 'speak'. It is possible to adjust the volume in this plugin; but a volume setting on the native 'speak' would be much more easy.
Is there a way? Any suggestions?
