Since I cannot view the innards of Dragon I could be off completely, but I think it could be due to the language model being adjusted.

When you add a word, it has to be added to the language model, otherwise Dragon would never be able to recognize it.

Adjusting/rebuilding the LM can be a time consuming effort, so it will not be performed synchronously.

This means that when you start a new recognition immediately after telling Dragon to add a new word, you'll get your results with the old LM or utterances are discarded because of the LM rebuild.

Once the LM has been updated, things go back to normal and you can use the new word.

 

I saw a note for a different SR system that stated a delay of up to half a minute until new words are recognized, so it could be similar with Dragon, only shorter.

 

Just my 2ct
