Comparison of Telephone Menu Interfaces
Conclusions
Impact for practitioners
We found out that small improvements could be made to increase the user satisfaction and speed of the menu systems in voice email systems. The higher pitch of a female computerized voice seems preferably to the subjects, and also improved performance times. The differences in menu levels could also improve the performance, where a two level approach gave an advantage over the three levels. A faster synthesized voice, with a female tone was also shown as preferable to the subjects.
Suggestions for future researchers
For a more thorough research, future experiments should include several menu systems that explore the breadth and depth of menu systems. The systems could also include the skip and scan method described in the introduction.
The subjective feedback can also be improved to show if a female computerized voice gives higher user satisfaction, as well as testing the cognitive processing, asking the subjects to explain what they heard.
Refine the theory or develop a new one
Our hypothesis did not prove to be statistically significant. The refined theory must include that a female voice can improve the speed and accuracy of a synthesized voice. The task could also have been refined, so the subjects had to recollect some parts of the message, to see how much of the message they understood.
