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.
