Auditory speedometer

How difficult would it be to enhance the callout "Traveling southwest along Main Street" to e.g. "Traveling southwest along Main Street at approximately 20 miles per hour?" How accurate would this number be? I know that Soundscape already has some mechanism for detecting when the user is in a moving vehicle, possibly based on moving speed, to determine how many points of interest it tries to announce.

See AlongRoadLocationCallout.sounds.

You can access the speed from CLLocation.speed. speedAccuracy is available on the same struct.

You'll have to add localized strings to handle the new utterances.

Thanks, Konstantin! That will be very handy knowledge when we get around to this feature.
