I wish I could return this program. All of the consonants have vowel sound voiced at the end, as in /d-uh/. This makes blending the sounds back to make a word impossible. I wrote SED for "said". When I tried to quickly push the letters so it would blend and read it back to me, it said, "/s/ /e/ /d-uh/." An incorrect representation of the phonemes is not very helpful.
