A list of strings containing words and phrases "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. See

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 and 20. We
recommend using a binary search approach to finding the
optimal value for your use case.
