	Anticipate Potential Problems and Issues

Another important area in planning a good speech application is to plan for any potential problems and error conditions that you can think of in advance. How is the system to respond when one of these problem situations arises?

• What are the technical or hardware limitations? What if the caller does not have a touchtone telephone? How does your system respond to TTY or TDD requests?

• Is accessibility for callers with physical limitations required? Have you allowed for the extra time it might take for callers with physical handicaps or other limitations?

• What language limitations will be incurred? Is it likely that some of your callers will need to interact using a different language than the primary language? Do you have the necessary ASR and TTS servers and software to accommodate them?

• What personal preferences are needed for callers? Have you allowed for the personal preferences of your callers? Some people would rather interact with the system verbally, while others might prefer to use DTMF (touchtone) responses. And, some people prefer to interact with a live attendant no matter how good your interactive voice response (IVR) speech application is.

• Such preferences are among the reasons that it is recommended that you always provide callers with an option to speak with a live attendant. Beyond personal preferences, it is likely that your system cannot deal with all eventualities and situations a caller might need help with. There are times when only a live attendant can take care of the need.
