Hate to burst the bubble here, but you need to realize that the ASR in the menu is not really good and has no real NLU - just word should matching. I would not suggest that for any customer. If you really want NLU manus instead of DTMF or in conjunction with it, you need to look at using a simple bot that can learn over time, actually listen for speech and use NLU for matching intents. We do this all the time with great success. The DialogEngine Bots are easy to build, learn on their own, and are great for ignoring background sound. I would try that first. Of course, there are other bots like DialogFlow and Lex that can also be used, but they are much harder to use than the ones in Genesys Cloud.
