    I’m still getting a lot of Ks where I should be getting As, but I think I’m going down the right path. Thanks again.

    Interesting. I’ll try pruning the dictionary of ambiguous pronunciations where possible. I’d like to do more with combinations like “A B”, but the that the characters being read to this application are random, so there won’t really be a pattern to which ones get combined more.

    Thanks for this help; I’ll report back if it’s more successful.

    With the dictionary/language model here, it’s giving me KB more frequently than AB (I was speaking “A B” each time):

    Sure, here’s the dictionary:

J	JH EY
K	K EY

Z	Z IY
ZERO	Z IH R OW
ZERO(2)	Z IY R OW

    EIGHT Y is accurate, I don’t have the transcription from before, though. I’ll try to get it to go again and post back here.

    The trouble is that it’s just not accurate enough distinguishing letters. I’m very new at using OpenEars/PocketSphinx, so really I just don’t know how to approach improving accuracy.

    The goal is for the user to read letters and numbers to be recognized by the app.
