Is there any way to change the announcement with an actual announcer voice instead of the google text to speech voice?
Most people will just find a coach or parent with a good voice and have them record announcements for each player either within the app or with a third party voice recorder and then import the files.
There is also the possibility to have a professional do them... https://upallnitesoftware.com/forum/index.php?topic=244.msg788#msg788 (https://upallnitesoftware.com/forum/index.php?topic=244.msg788#msg788)
