estimatedAudioCueDuration property
getter/setter pair
Estimation of the required time to play an audio cue at speech rate 1.0. For example the cue "Turn right on Name-Of-A-Street" will playback over an X number of milliseconds. Therefore, an estimation of this audio cue duration is needed to correctly sync the movement of sound to the cue (so that audio movement and audio duration match).
