Built a free tool to practice the sound pairs that trip up learners most (ship/sheep, etc.) — curious what you'd add

A lot of the accent feedback I see here comes down to a handful of recurring sound confusions — vowel length (ship/sheep), th-sounds, r/l for some learners, etc. I built a free site called SoundPairs.com that breaks these down individually: mouth shape, audio, example sentences, what's actually different between the two sounds.

Not trying to replace the feedback you get here — more like a practice tool between rounds of posting recordings. No signup needed to browse.

If you've got a specific pair that's been driving you crazy, let me know — I'm adding new ones regularly and would love suggestions from people actually working on this stuff.
