Note

Short words are often more difficult to interpret and handle in terms of speech recognition than longer phrases, so “I am fine” is more likely to be recognized correctly than just “fine.”

To solve this, it’s possible to map the word “find” to “fine” in these states. Another example is a user who asked, “What is the pool depth?” but the recognizer returned “what is the pool death.” If this is a common occurrence, adding “pool death” to the accepted key phrases is straightforward. In addition, using an N-best list would help with this issue; “pool depth” is a likely occurrence later in the list, and walking through it until a more relevant match occurs, rather than just choosing the first, will automatically improve your VUI’s accuracy.
