Provides the instruction string which was build on the server-side and can sometimes concatenate instructions together if maneuver instructions are too close to each other.
This provides the missing piece in which is needed to announce instructions at accurate times. If the user is less distance away from the maneuver than what this distanceAlongGeometry() than, the announcement should be called.
Get the same instruction string you'd get from .announcement but this one includes Speech Synthesis Markup Language which helps voice synthesiser read information more humanely.
