In kotu, are there benefits if you use "only devoiced sounds" and "muffled voices" in the perception test?

You can use the devoiced sounds checkbox to specifically work on those if you have an issue with them. They tend to be harder.
I don't find the muffled checkbox to be useful, but I think it was added for people who have an issue identifying pitch when it sounds too much like speech (i.e., to make it sound less like speech)
