Once you enable the player announcements... The app will automatically announce the players name and number that you entered as the walkout song you have chosen for that player fades out. So just add a player with a name and number, select a walkout song for them, and then tap the play button to the left of the player and you should hear the walkout song play and fade and then the player announcement at the end. Not much more to it.
You can select a voice for the announcements if you don't like the default. That option is available from the menu where you enabled the announcement. You can also speed up or slow down the announcement in that same place because Apple tends to adjust that speech rate with every release of iOS.
