This is probably the most common complaint of language learners!
Audio courses try to help, having the sentences voiced by native-speaking actors, but even this can be too fast for a beginner.
Goalpost provides special buttons to progessively increase or decrease the
speed at which you hear the language spoken. You can start at the slowest speed and adjust it faster as your ability to hear the language improves.
The app offers an eight steps speed range: from extra slow speed, through steady speaking speed, to rapid native-speaker speed.
