This is unfortunately a thing which gets bad results with speech recognition. Most of the words are a single syllable, many of those syllables rhyme with each other (three, e, d, g, p) or nearly rhyme (eight and a and j), and they are contextless – they can arrive in any order (in contrast to phrases of words where we can say that some combinations are more likely, or required by a rule, versus others). You can probably find several other discussions on these forums about this, but they mostly consist of me making this approximate statement.

You can fix the fact that the letters are spelled phonetically, since that will prevent them from being found in the lookup list and given multiple pronunciations if there are some, but the main way to improve would be a specification change of some kind (organize your app so that only a few of these items are in any given language model or grammar – you will still encounter the e/d/g/p issue, but it will be a bit reduced).
