No voice input means that you can not initiate calls via voice recognition. With voice recognition, you push and hold the "sneezing man" button and tell the car either a phone number or use name. Then, it talks to the phone and makes the call. I love it and use it almost exclusively to call out. Others don't like voice recognition and never use it. It is personal preference.
