2. Airflow: You need to maintain a steady airflow while transitioning between the two vowel sounds. Focus on a smooth shift from the /aʊ/ sound to the /uː/ sound without any interruption in airflow.

3. Practice: Repeat words containing the “ou” diphthong like “house,” “mouse,” “about,” and “shout.” Make sure to pay attention to the transition between the sounds. You can also try tongue twisters, listen to native speakers, and practice mimicking their pronunciation.

4. Feedback: Record yourself while practicing and compare it to native speakers’ pronunciation. You can also seek feedback from English speakers to help you identify any areas that need improvement.
