Speaking exercises

Before the latest updates, the speaking exercises started after you pressed the mic button. Now they start as soon as the character finishes talking. I find this very frustrating, as I frequently need to read it first, comprehend it and then speak. By the time I do all that, it comes up as a “failed attempt,” which didn’t happen before. Does anyone know if it is possible to revert to the previous mode? Anyone else frustrated with the same?
