Hint Boost. 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 will simply be ignored. Though boost can
accept a wide range of positive values, most use cases are best served with
values between 0 (exclusive) and 20. 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.
