Hello,
This question is a bit confusing. Can you explain why you don’t listen continuously and change between your vocabularies based on the logical state of your app?
SaveThatWave isn’t designed to record speech to be submitted to the wav recognition function, and the wav recognition function isn’t designed to be used on live speech, so there is no reason this would result in an effect similar to continuous recognition and it would be unfruitful to troubleshoot why it doesn’t have that effect.
But the library performs continuous recognition by default and is intended to be used with many small vocabularies, so it would be a better approach to start with the reason that you aren’t using the functionality that matches your requirements, and troubleshoot that if it is possible.
