Should My GPS Have a Voice Processor?

One of the primary considerations in purchasing a GPS is whether the unit includes a voice processor.

A voice processor allows your your GPS unit to convert text into spoken words. Some basic GPS units do not come with this functionality. Instead, they have a set of pre-recorded commands: Turn left ahead, keep right, approaching destination, etc. A unit that comes with a voice processor will be able to say, “Turn left on Main Street” instead of simply, “Turn left”.

Why does it Matter?

It’s important because there are times when it’s unclear which street your GPS is referring to when streets come close together. There are enough distractions on the road, and the less you need to look at the screen of your GPS, the better. When you’re searching out street signs, not having to look down at your GPS screen to make sure you have the right street makes a difference.

The small details about how your GPS interacts with you make a big difference in safety. A well-thought out and designed unit will be less of a distraction. Make sure you buy a unit that works smoothly and drive carefully, programming your destination before you start driving.

Determining whether a unit you are considering has a voice processor can be tough, because very few stores list ‘voice processor’ on the spec sheet. Often, they will use phrases like, ’speaks street names’, or ‘text-to-speech’. If you aren’t sure, call customer support and ask a few questions.

A voice processor should not be confused with voice command. Some GPS units recognize speech. You can select a destination solely by using your voice. This is only available on a very few high end models so far. It offers yet another level of handsfree interactivity, because you don’t need to look at the screen or use the touchscreen to select a destination, leaving you free to focus on the road.
