Goalpost relies on the language voices supplied with your device.
You may need to install these.
We would love to be able to install them for you, to save you the
trouble but, unfortunately, device manufacturers do not allow apps to do this, for security reasons.
Fortunately, it is not difficult to install foreign language audio voices yourself!
Follow this sequence of instructions to install
language speaking voices on your device.
1. Go to Settings.
2. Click on "Time and Language".
