 The original audio can thus be heard to some extent, allowing the viewer to grasp the actors' voices, yet due to the lack of synchronisation between original dialogue and a voice-over, original music is usually a victim of lowering the original track's volume.The voice-over usually contains only a hint of emotion, as many of the interpreters try to sound "transparent" to the audience.A significant drawback of such dubbing is the ambiguity as to which character is speaking at a given time, as the interpreter usually makes very few changes in intonation to distinguish between different participants in a dialogue.
