WholeWord speech recognition supports word spotting. Word spotting is the ability of the system to ignore extraneous speech during speech recognition. For example, if a caller says, "I want number five, please," the system recognizes the word "five" as a valid response and ignores the rest of the input. In other words, callers do not have to speak the key word, which in this case, is "five" in isolation. The caller can speak other words, and the system can distinguish the key word from the extraneous words.
This means that the caller's input is not limited to the words in the system vocabulary. For example, in the phrase "Uh, yes please," the vocabulary word "yes" is recognized if the system is using the standard vocabulary.
However, to maintain good recognition accuracy, it is advisable to structure the application to prompt the caller for the required information only.
