I thought "ts" should sound differently. I believe rights and rice are not homophones; if so, why should patients and patience be homophones? Because the sound t is canceled after n?
These two words, Patients vs. Patience, are no different. The words patients and patience are homophones, which mean they sound the same when they are spoken, but when they are spelt, spellings are different and have different meanings. — Toppr
