When you modify a touchtone input application to support spoken input (in addition to or in place of touchtone input), remember to examine the application to see what the prompts say and what action is expected from callers. Think about the capabilities of the speech recognition software you will be using, and where they might fit into the application.
The following table shows the words the wordlist might contain for a homework assignment application:

If you plan to use WholeWord speech recognition, your application will be able to recognize the words "yes" and "no" and connected digits. In places where the touchtone application prompts for digit entry (especially long sequences), you may want to introduce custom grammars, checksums, or grouping to get the highest recognition accuracy possible.
