The talking speedometer uses GPS to calculate your speed.
The female voice reads your speed every 5 or every 10 units (kmph or mph)
When your speed is greater than the alarm treshold then default sound or your selected ringtone makes noise ;)

THE GPS MUST BE ENABLED ON YOUR DEVICE !!! SWITCH IT ON FIRST IF IT IS NOT RUNNING!

There are two language versions of voice: english and polish.
Just listen to the reader.
Keep your speed!
Look forward!
And drive safely.
