Zoo Isn't Sue: Give Z Its Buzz

Thai has no 'z' sound at all, so many Thai speakers naturally substitute the familiar 's' instead, turning 'zoo' into 'sue' and 'busy' into 'bussy'. The fix is small but important: 's' and 'z' are made with your tongue and lips in exactly the same position, the only difference is that 'z' turns your voice on, creating a gentle buzz in your throat while the air still hisses through. Put two fingers on your throat and say a long 'ssss', no vibration. Now say 'zzzz', you should feel a clear buzz. Try the pairs 'sip / zip', 'ice / eyes', and 'race / raise', switching the buzz on only for the second word each time. For today's two-minute practice, alternate slowly between 'ssss' and 'zzzz' ten times with your fingers on your throat, feeling the vibration turn on and off like a switch. Once that feels easy, move into full words. This tiny buzz matters a lot in English, since it's also what marks plurals like 'dogs' and verbs like 'runs'.
