A Phrase contains words and phrase "hints" so that the speech
recognition is more likely to recognize them. This can be used
to improve the accuracy for specific words and phrases, for
example, if specific commands are typically spoken by the user.
This can also be used to add additional words to the vocabulary
of the recognizer.
List items can also include CustomClass references containing
groups of words that represent common concepts that occur in
natural language.

Hint Boost. Overrides the boost set at the
phrase set level. Positive value will increase
the probability that a specific phrase will be
recognized over other similar sounding phrases.
The higher the boost, the higher the chance of
false positive recognition as well. Negative
boost values would correspond to anti-biasing.
Anti-biasing is not enabled, so negative boost
values will return an error. Boost values must
be between 0 and 20. Any values outside that
range will return an error. We recommend using a
binary search approach to finding the optimal
value for your use case as well as adding
phrases both with and without boost to your
requests.
