You have now learned fourteen regional labs and the shared core. The last trap is to use them backwards: to hear a feature and decide where a person is from, then expect the rest of that lab to follow. In India's big cities this fails constantly, because the cities are where the labs mix. What you will learn: • Why cities mix • The typical mixes, city by city • Why features "Don't match" • Decoding by features, not origin • What not to do in A mixed city • The decode routine for mixed speech • Practice: decode the sentence • 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.
