Spoken Language
Spoken Language
- Natural
- Flexible
- Efficient
- Economical
Particularly powerful when:
- Information space broad and complex
- Users technically naive
- Only telephone available
- Combined with graphical interface
Notes:
- Natural: Requires no special training.
- Flexible: Leaves hands and eyes free.
- Efficient: Has high input data rate, especially for complex concepts.
- Economical: Can be transmitted and received inexpensively.
- Information space broad and complex - e.g. Air travel reservation.
- Combined with graphical interface - Consider combination of speech and GUI and not just each in isolation. e.g. Getting weather report in the morning.
