Hangouts Ring Tone Interfering With Hands Free Voice Commands

[jipr]

When I'm driving and receive a text the 'google voice' announce who the incoming text is from then asks me to say 'listen' if I want to hear it. The issue is that sometimes the ring tone interferes with my spoken command and I cannot hear the text and subsequently respond to it. Aside from turning off the ring tone are there any ideas how I can remedy this?
