Speech Element

A speech element is used to present several speech commands to the caller.

*** Important Note: Speech recognition is not 100% accurate, especially when it is applied over the spoken command over the telephone lines. Design a good voice user interface (VUI) is important for a successful IVR application. For example, it is much easier for the speech recognition engine to differentiate "yes" and "I do not agree" than "yes" and "no". ***
