Non-speech audio messages called earcons can provide powerful navigation cues in menu hierarchies. However, previous research on earcons has not addressed the particular problems of menus in telephone-based interfaces (TBI's) such as: Does the lower quality of sound in TBI's lower recall rates, can users remember earcons over a period of time and what effect does training type have on recall. An experiment was conducted and results showed that sound quality did lower the recall of earcons. However, redisgn of the earcons overcame this problem with 73 % recalled correctly. Participants could still recall earcons at this level after a week had passed. Training type also affected recall. With 'personal training' participants recalled 73% of the earcons but with purely textual training results were significantly lower. These results show that earcons can provide excellent navigation cues for telephone-based interfaces
