Is there a way to at least get the vocabulary lists on the device instead of typing all possible words?
I don’t quite understand this question — can you clarify what you are wanting to do here a bit more?
For the numbers, I’ve added ’1′ along with ‘WORD’ & ‘STATEMENT’ and when I said ’1′, it returns ‘WORD’. why is that? Also, when ’1′ and ‘ONE’ is added, ‘ONE’ always returns; Does it mean that its more likely to return words instead of numbers?
This is probably because “ONE” is finding a more accurate pronunciation match in the dictionary for your accent. If “1” is giving undesired results and “ONE” isn’t, go with “ONE”. It’s always necessary to do a bit of refinement on a vocabulary for best results.
