when speakers can see each other on a low frame-rate video screen, they articulate more clearly than the case where they cannot see each other and are communicating only over an audio link

With mobile phones in use around the world already numbering about 1.3 billion, some 450m new handsets are still being bought every year (most people upgrade their handsets every couple of years).
