Sh Needs Rounder Lips Than Ch

Here's a subtle mix-up that can quietly confuse listeners: the 'sh' sound in 'she' and the 'ch' sound in 'chip' use almost the same part of the tongue, so it's easy to let them blend, especially in fast speech. But in English, they're two distinct sounds — 'sh' is a smooth, continuous hiss, while 'ch' starts with a quick stop before releasing into that hiss. Mixing them changes real words: 'sheep' becomes 'cheap,' 'wish' becomes 'witch,' 'share' becomes 'chair.' Try this two-minute drill: say 'sh, sh, sh' and hold the sound steady for two full seconds, feeling the air flow continuously with no interruption. Then say 'ch, ch, ch,' noticing the tiny stop-and-release at the start of each one. Once you feel the difference, practice the pairs 'sheep/cheap' and 'wash/watch' slowly, then a bit faster. This is a small, precise fix, and once your mouth learns the difference, it tends to stick for good.
