Welcome,
I would try RapidEars first to see if the accuracy is an issue, but if it is, you can use them both in the same app because they are started with separate start commands. The issue is that you can’t switch between them right in the middle of a recognition session, so you have to stop the recognition of one and then start a new recognition with the other. The only real downside to this is that it is necessary to recalibrate.
