Pronunciation is a physical activity. Let's do warm-up exercises!
Find time to do physical exercises every day to build and develop flexibility in your speaking apparatus. Stretch your face, your lips, your tongue.
No fees! No uniform! No equipment! Do it! Work out!
When working on your accent you need to build up your muscles - the tongue, lips and cheeks.. Do this warm up every morning or before important talks and you'll feel the improvement in your pronunciation!
