Applications
1&period; Tour guide systems are used in Tourist Attractions for each tourist hear Commentary clearly&period;
2&period; Tour guide systems are used in factories for showing visitors round&comma; for training where machinery noise makes it hard for trainees to hear their instructors&period;
3&period; In public meetings as an interpretation system&period; The interpreter can simply sit at the back of the room and whisper the translation into the microphone&period;
Tour guide systems operate on different frequencies which means that several different languages can be catered for at the same time&period;
