What will be an ideal response?
Speech production is usually successful when the messages are simple and short; and users’ visual channels are overloaded.
There are three general methods to produce speech:
1. Formant synthesis – machine-generated speech using algorithms
2. Concatenated synthesis – uses tiny, recorded human speech segments
3. Canned speech – fixed, digitized speech segments
Examples include:
Audio books or audio tours
Instructional systems
Online help systems
Alerts and warnings
