Voice Command Question

Wildman

Today I went to use my voice command to look up a contact and not shortly after that I went to navigate to a location on Google Navigation  by voice, when all the sudden my brain clicked and I was wondering if there was any sound reason for them to install so many different voice commands on one device, wouldnt it make since to have just one that does it all, I noticed that one seems to understand commands better than others and this is kind of crazy having multiple voice commands apps running all the time..

Its not a issue but I was wondering if someone can enlighten me on the logic?

After I posted this, I believe I figured out Verizons and Motorolas logic....... Since the voice command that completes the navigation and Voice to text actions through a web base application that has to retrieve information from web to complete request that at times may not be possible, the standard voice command application is a software based action that will allow you to access the contacts information that is saved on device... It is still a unique way to configure a device but in a way it has some logic.
