From this example, the user has 5 seconds to say either one or two. If the user does not say anything within these 5 seconds, then an incompletetimeout will occur and return a <noinput> to the user. When a user begins to say either one or two, the application waits for 5 seconds due to incompletetimeout. Once 5 seconds has passed, the application returns a response to the user.
