Most international work with Indian colleagues now happens on video calls, and video is hard on gestures. The camera flattens depth, the frame cuts off the hands, the connection drops frames, and a small tile on a busy screen shows you a moving head without the face detail you need. On a small screen a wobble can look like a shake, a nod can freeze halfway, and a slow tilt can look like nothing at all. What you will learn: • What the camera does to gestures • How each gesture looks on screen • The muted-microphone problem • Confirm in words • Making your own signals clear • Camera-off calls and phone calls • Practice: decode the scene • Listening strategies • Self-check questions to test your ear Level: B1–B2. Self-study: listen, then take the quizzes. Audio voiced with AI from an original script by Dr. Rashmi R Nair.
